In Memoriam (Boris Kuperman)
Where are They Now?
This has obviously been another busy year for ichthyoparasitologists
judging from the amount of news I was sent with very little begging on
my part. A record number of "Research Activities in Various Countries"
reports were sent to me, with 10 countries or regions represented. A new
"Where are They Now?" section has been added to the Newsletter
at the request of a number readers. This section allows researchers to
inform their colleagues of their new details if they have moved or changed
jobs. Sadly, an "In Memoriam" section has also been included
in this issue to announce the passing of Professor Boris Kuperman, a notable
Anyone wishing to contribute to the next issue of
the Newsletter (Number 11) should note that the deadline date for submission
is September 30, 2003.

Sixth International Symposium on Fish Parasites will be hosted by the
University of the Free State in Bloemfontein, South Africa from 22
- 26 September, 2003.
The International Steering Committee for the Sixth
International Symposium on Fish Parasites selected this venue based on
a bid submitted by the Aquatic Parasitology Research Group of the Department
of Zoology and Entomology of the Free State University after the Aberdeen
Group withdrew their offer to host the meeting in 2003.
The conference will be hosted on the Bloemfontein
campus of the University of the Free State. Bloemfontein is a friendly
small city and the capital of the Free State. It is also the judicial
capital of South Africa and the seat of the Appeal Court. Bloemfontein
Airport has daily flights in and out to Johannesburg and Cape Town as
well as to other major centres.
The city is well known for its hospitality and safety.
The climate during late September will be mild with the possibility of
isolated thunderstorms, which mostly last only for an hour or two. The
organising committee is committed to stage an international symposium
of a high standard, but at an affordable cost in order to attract as many
participants as possible, especially post graduate students.
The date of the symposium, 22 – 26 September 2003,
was selected to coincide with the university recess, so that university
residence accommodation could be made available for delegates if they
chose to make use of it. The cost will be around $15-20 US per person
per day and will include breakfast. There are numerous guesthouses as
well as four hotels within walking distance from the campus. Information
about the cost of this accommodation will be included in the circular,
which will go out in February 2003.
The organising committee of the Sixth International
Symposium on Fish Parasites requests that anyone interested in attending
contact us by e-mail so that we can place you on our mailing list. We
also request that you pass this announcement on to anyone that you know
who may be interested in attending.
We are looking forward to receiving you in Bloemfontein.

This workshop consists of three modules that can be
taken separately or together. These modules are described below. The workshop
is designed to suit postgraduate students and postdoctoral fellows who
are interested in learning histopathology, but also as an introduction
to aquatic animals for veterinarian pathologists or as a revision for
experienced pathologists. Participants will be divided into smaller groups
on the basis of their experience. The small group size will allow for
teaching at different levels related to the experience of the participants.
Participants are encouraged to bring their own slides for discussion.
All prices are quoted in Australian dollars. Contact Barbara Nowak (email@example.com)
for further information.
Fish Histopathology. Monday February 10 to
Wednesday February 12, 2003. Fee: $600. Laboratory style (limit 12).
The two day intensive workshop will focus on histopathology
of fish organs and tissues. The lecturers include Dr Judy Handlinger,
Dr Barry Munday, Dr Barbara Nowak, Dr Tish Pankhurst and Dr Mark Powell.
Generally, classes will be taught in small groups (approximately 4
persons in each) to accommodate the different levels of experience. As
a result, participants are not required to have extensive histology background,
however, experienced pathologists will also find it useful. Conference
microscopes, slide projectors and computer software will help to illustrate
fish histopathology. The program will include examples from a variety
of fish species, both marine and freshwater. The use of histopathology
in disease diagnosis and its use as a pollution biomarker will be discussed.
Participants are encouraged to bring their own slides for discussion.
Crustacean Histopathology. Thursday February
14, 2003. Fee: $300. Laboratory style (limit 12).
The lecturers include Dr Danielle Johnston, Dr Steve
Pyecroft and Dr Barbara Nowak. Generally, classes will be taught
in small groups (approximately 4 persons in each) to accommodate the different
levels of experience. As a result, participants are not required to have
extensive histology background, however, experienced pathologists will
also find it useful. Conference microscopes, slide projectors and computer
software will help to illustrate crustacean histopathology. The program
will include examples from a variety of crustacean species, focusing on
penaeid shrimp. The use of histopathology in disease diagnosis and its
use as a pollution biomarker will be discussed. Participants are encouraged
to bring their own slides for discussion.
Molluscan Histopathology. Friday February
15, 2003. Fee: $200. Demonstration lecture style.
The one day intensive workshop will focus on Histopathology
of molluscan organs and tissues. Dr Judith Handlinger will be the
workshop leader. Generally, lectures will be used to illustrate
molluscan histopathology. The program will include examples from a variety
of species, focusing on the ones most important in aquaculture. The use
of histopathology in disease diagnosis and its use as a pollution biomarker
will be discussed. Participants are encouraged to bring their own slides

IMMUNE RESPONSE AND VACCINE DEVELOPMENT
Friday April 11, 2003
A half-day workshop sponsored by Cooperative Research
Centre for Sustainable Aquaculture of Finfish (Aquafin CRC) will be run
during the Fish Vaccinology Conference to be held in Bergen, Norway, April
9 – 11, 2003. This workshop will cover recent advances in studies of fish
immune response to ectoparasites and development of vaccines against external
parasites. Dr Chris Prideaux, CSIRO Australia, will give a presentation
on the development of tick vaccine for livestock and potential lessons
for aquaculture vaccines against ectoparasites. Current research on monogenean
infestations, white spot, sea lice and amoebic gill disease will be covered
by invited speakers. We will discuss main challenges in these research
areas and ways to overcome them. We are hoping that the workshop will
lead to development of future collaborations. Additional information and
registration forms can be found on the website: http://veso.no/courses/fishvaccinology/workshops.html

4th International Symposium
on Aquatic Animal Health, New Orleans
provided by Barbara Nowak, firstname.lastname@example.org
Dr Barbara Nowak and Dr Mark Powell (School of Aquaculture,
University of Tasmania) attended the 4th Symposium on Aquatic
Animal Health in New Orleans, Louisiana, USA between September 2 and 6,
2002. The symposium program comprised over 300 contributions, including
a number of plenary speakers providing updates in different areas of aquatic
animal health. There were 11 special sessions, 25 contributed sessions
and almost 100 posters. A wide range of topics was covered by leading
scientists in each field, presenting the most recent data available. Four
sessions were fully dedicated to parasitology. There were also some presentations
discussing pathology or epidemiology of parasitic diseases. Some of the
interesting talks included presentations on the life stages of the rosette
agent, analysis of costia isolates and a plenary session on the transmission
of myxozoan parasites – interactions between wild and cultured fish.
Dr Kristen Arkush (University of California) classified
the rosette agent as a new genus and species sharing similar morphological
characteristics with members of the class Mesomycetozoea, a novel group
of parasites of fish, shellfish, mammals and birds, near the choanoflagellates,
in the divergence between animals and fungi. Studies of rosette agent
from infected fish tissue and as propagated in cell cultures have revealed
previously unrecognised life stages of the parasite.
Dr Heather Callahan (North Carolina State University)
presented genetic evidence for more than one species of costia.
On the basis of SSU rRNA, the parasite was described as a complex of at
least four groups that probably represent different species. One group
consisted of hybrid striped bass and swordtail isolates, the second and
third group consisted of the rainbow trout and mirror carp isolates and
the fourth group consisted of koi, goldfish, catfish and flounder isolates.
This separation was geographical and related to fish movements.
Dr Jerri Bartholomew (Oregon State University) in
her plenary lecture discussed transmission/dissemination of myxozoans,
including transfer of naïve fish into enzootic waters (for example
Ceratomyxa shasta) or transfer of infected fish in stocking or
enhancement programs (for example Myxobolus cerebralis), by natural
migration or as a food product.
Dr Powell gave a presentation on insights into pathophysiology
and treatment of Amoebic Gill Disease in Atlantic salmon. Dr Nowak presented
a paper on Amoebic Gill Disease in cultured salmonids in Australia and
another one on evaluation of health risks to the farmed southern bluefin
tuna. Salmonid health was an important focus of the symposium and in particular,
there were special sessions on Infectious Salmon Anaemia, including development
of diagnostics and vaccines, as well as epidemiology of this disease.
Some papers focused on non-infectious problems in salmon farming. For
example, cataract prevention in Atlantic salmon by incorporating histidine
in the diet and avoiding osmotic shocks during culture was discussed.
The life cycle and toxicity of Pfiesteria sp were questioned in
three papers presented in the session on toxicology. Other interesting
information presented included research on prions in fish that suggested
that it is highly unlikely that fish would contract transmissible spongiform
encephalopathy and therefore should not pose a potential food safety risk

ICOPA took place between August 4th and
9th at the Vancouver Convention and Exhibition Centre in Canada.
There was potentially a lot to interest fish parasitologists, but unfortunately
attendance was down, there were numerous ‘no shows’ and the fact that
there were up to 16 concurrent sessions meant that, if one had interests
in other areas, actually getting to attend relevant sessions was not easy.
Of interest to fish parasitologists were five sessions entitled Ichthyoparasitology,
two sessions on Ectoparasites, a symposium on Parasites as Indicators
in Aquatic Biology plus sessions on Ecology, Wildlife
Parasitology and Parasitological Surveys which contained material
of relevance. In addition, Dave Marcogliese’s ‘stickleback club’ had a
workshop (see below) on the Biodiversity of Stickleback Parasites,
there was a symposium on Advances in the Study of Parasites of Marine
Mammals which was of some interest to fish parasitologists and a small
number of posters were presented in sessions on Ecology (2), Ectoparasites
(2), Food/water-borne parasites (2) and Ichthyoparasitology
(10). For the specialist, this type of large meeting cannot be compared
with more focused symposia, such as we fish parasitologists have. There
were, however, particular failings at this, not so cheap meeting, such
as speakers having to find or provide a laptop for their presentation,
and, important for fish parasitologists, the
absence of free drinks. Nevertheless, Vancouver is a nice place to hold
a meeting – with a fireworks competition in the evenings and trips to
the mountains and to the aquarium to see the baby beluga whale,
attendees will not have been too disappointed.

One satellite meeting worth mentioning
is the Fourth Cestode Systematics Workshop organised and
very well run by Janine Caira and her group at the University of Connecticut
the week before ICOPA. This meeting was dominated by fish parasitologists,
and, although perhaps too much time was spent discussing terminology,
all attendees had a good time and likely added a kilo or two to their
midriff. A good aspect of the meeting was the presence of a number of
senior fish parasitologists, some of whom are not often seen at meetings
these days – these included Louis Euzet, Haffi Williams,
John Mackiewicz, Amilcar Rego, Boris Kuperman (who
unfortunately passed away on the last day of ICOPA), Juan Carvajal,
Ron Campbell, Claude Alexander and Ian Beveridge.

FIRST STICKLEBACK PARASITE WORKSHOP
provided by David Marcogliese, firstname.lastname@example.org
A workshop for the IBOY core project "Survey
of Stickleback Parasites" was held in Vancouver on August 5, 2002,
during the International Congress of Parasitology. This is the first time
participants in the project have been able to assemble to discuss the
project. Over a dozen participants from the US, Canada, Scotland, Germany,
Iceland, and Iran were able to attend. In addition, the workshop attracted
a number of curious visitors and a few new participants were recruited.
Being the first gathering for the project, the workshop
consisted of discussion and verification of logistical details, including
fish collecting and processing, specimen preparation and identification,
and data formatting. Extensive discussion ensued on data management and
analysis. Other topics covered include publication and authorship, deposition
of voucher specimens, funding, products and product development (including
web pages and a web site) and planning for future workshops.
As a result of the workshop, important activities
were identified and prioritized in addition to the accumulation of stickleback
parasite data and its analysis. These include the synthesis of a host-parasite
checklist, a parasite bibliography for sticklebacks and a list of museum
collections of stickleback parasites. In addition, the scope of the project
was expanded to accept all parasitological data for sticklebacks, including
those dealing only with select parasite groups. One accessory benefit
from this project for the scientific community at large is that it can
provide both fish and parasite tissues from around the world for colleagues
studying this widespread and important group of fishes.
EIGHTH INTERNATIONAL CONFERENCE
provided by, Wojciech Piasecki email@example.com
International conferences on Copepoda are organised
every three years under the auspices of the World Association of Copepodologists
(WAC). Crustaceans representing the subphylum Copepoda are very diversified
ecologically. Even if this group has been perceived predominantly as consisting
of small free-living, chiefly planktonic invertebrates, we cannot forget
that they also constitute a major group of fish parasites. Therefore,
for many years now, ichthyoparasitologists working on Copepoda have been
attending the conferences organised by the WAC, considering them as the
major event in their field.
The 8th International Conference on Copepoda
was held between 21-26 July 2002 in Keelung, Taiwan. It was locally organised
by the National Taiwan Ocean University and the National Museum of Marine
Biology and Aquarium. The conference venue was at the beautiful campus
of the National Taiwan Ocean University, located on the northern shores
of Taiwan. The chairman of the Local Organising Committee, Prof. Dr Jiang-Shiou
Hwangn, was able to recruit many sponsors, which translated into financial
support for many PhD students, people from developing countries, and invited
The schedule of the conference was very tight and
the symposia lasted from early morning to late evening. The program included
four major symposia, two evening symposia with 40-min talks, 16 oral sessions
with 20-min talks, and four 1.5-h poster sessions. Papers dealing with
parasitic copepods were a minority, but there were many presentations
covering both free-living and parasitic copepods and there were many papers
of a general nature which were of interest to ichthyoparsitologists (development,
phylogeny, molecular methods etc.)
Symposium I was dominated by ichthyoparasitologists.
Wojciech Piasecki from Poland talked about the role of copepods
in freshwater aquaculture, Stewart Johnson from Canada—the role
of marine copepods and James Bron from Scotland—aspects of control
of parasitic copepods. Oral Session III on "Symbiotic copepods"
featured very interesting presentations by: Dennyse Newbound, Australia
(on a biological tag of whale sharks), Julianne Kalman, USA (parasites
as pollution indicators), James Bron (cuticular elemental signatures—for
discriminating salmon louse populations) and Argun Özak from
Turkey (aspects of Caligus minimus treatment). Parasitological
papers were also presented during other Oral Symposia. James Bron talked
about exocrine glands of Lepeophtheirus salmonis, Susan Dippenaar
from South Africa presented a molecular approach to the phylogeny of seven
siphonostomatoid families, and N. Nguyen from Denmark talked about
ectoparasites of cod. Finally a feature presentation of the Evening Symposium
I was a paper by Ju-shey Ho entitled "Eudactylinid copepods
and their fish hosts: co-evolution and opportunism". Prof. Dr Ho,
as a member of the International Organising Committee, extensively contributed
to the success of this conference by his involvement in its organisation.
Two poster sessions on symbiotic copepods gathered
13 posters, mostly on parasites of fishes. The presenting authors were:
S. Ohtsuka (ergasilids in plankton), S. Okabe (copepod parasites
of a puffer fish), I.-H. Kim (poecilostomatoid associates of bivalves,
Korea), D. Tang (parasitic copepods of marine teleosts, Australia),
S. Gómez (life cycle of Lepeophtheirus simplex),
N. Lopez (parasitic copepods fishes, Philippines), H. El-Rashidy
(antennae in Ergasilidae), S. Urawa (Neoergasilus in Japan),
A. Ingram (antennae in Anthosoma crassum), A. Avenant-Oldewage
(comments on life cycle of Lamproglena clariae)(Lamproglena
and Lernaea as environmental indicators), R. Castro-Romero
(new siphonostome species and genus) and K. Nagasawa (sea lice in Japan—a
conference was exceptionally well organised and, I myself, really enjoyed
attending this event. I would like to take this opportunity thank the
Organising Committee and especially Professors: Dr Jiang-Shiu Hwang of
Taiwan and Dr Ju-shey Ho of the USA for sponsoring my attendance as an
invited speaker. The conference gathered scientists from 49 countries.
The proceedings will be published in Zoological Studies.
A multidisciplinary approach using
genetic markers and biological tags
in horse mackerel (Trachurus trachurus)
stock structure analysis
This project, funded by the EU Commission within the
5th Framework Programme, Quality of Life and Management of
Living Resources (Key Action 5: Sustainable agriculture, fisheries and
forestry), was described in the last Newsletter. Funding for HOMSIR finishes
at the end of this year, but we have negotiated an extension for six months
to allow us to write up the final report and prepare publications. The
following brief summary will remind readers of the objectives and gives
some preliminary results.
The overall objective of HOMSIR is the biological
stock identification of the horse mackerel (Trachurus trachurus)
throughout its entire range, from the North-east Atlantic to the Mediterranean
Sea. This goal will be achieved integrating both established and innovative
approaches such as genetic markers, other biological tags (morphometry,
parasites), tagging experiments and life history traits (growth, reproduction
and distribution). Partners involved in the use of parasites as biological
tags are: Ken MacKenzie and Neil Campbell (Department of
Zoology, The University of Aberdeen, Aberdeen, Scotland); Simonetta
Mattiucci (Institute of Parasitology, University of Rome "La
Sapienza", Rome, Italy); and Paula Ramos and Ana Pereira
(IPIMAR, Lisbon, Portugal).
Thirty-four species and six higher taxa of parasites,
including seven new host records, have been recorded from the horse mackerel
examined to date. For a recent update on the project, see : Campbell,
N., MacKenzie, K., Mattiucci, S., Ramos, P., Pereira, A. and Abaunza,

After organizing the 4th International
Symposium on Monogenea (ISM4) held in Brisbane in July 2001, the Monogenean
Research Laboratory (MRL) moved from The University of Queensland in Brisbane.
As of late December 2001, the MRL is based in South Australia and personnel
are to be found at 2 prestigious research institutions in Adelaide. Ian
Whittington is a Senior Research Scientist at The South Australian
Museum (SAMA), which also houses the Australian Helminthological Collection
for which Ian has nominal responsibility. SAMA has formidable research
strengths and there is scope for much fruitful future collaboration, especially
with the Evolutionary Biology Unit. Ian is also cross appointed with the
Department of Environmental Biology (DEB) at The University of Adelaide,
a vibrant academic unit with strengths in physiology, ecology and systematics.
A healthy focus on marine biology and ecology, biodiversity, systematics
and evolutionary biology means that the research programs of the MRL (see
below) integrate well in this new environment. SAMA and DEB are only a
1-minute walk apart which further strengthens the link between Museum
and University. The MRL currently comprises: Clinton Chambers,
Leslie Chisholm, Ingo Ernst, Vanessa Glennon and
Ian Whittington. 2002 has been a year of consolidation after the move
of institution. Now we’re settled, we seek new students to help us with
our research on various aspects of the Monogenea. Our core programs are
Taxonomy, biology & ecology of capsalid monogeneans
Ian has long had interests in capsalid monogeneans
from the Great Barrier Reef, other regions of Australia, more temperate
waters of Europe and most recently has experience of them as disease agents
in aquaculture (see below). Marty Deveney (now employed as Project
Officer [Fish Health] with Primary Industries & Resources South Australia;
recently completed his PhD thesis on the taxonomy and biology of capsalids
and more publications will emerge from his study. There is also a diversity
of capsalids in Ian’s collection that await description and a preliminary
phylogenetic analysis promises some interesting times ahead, using sequence
data and morphology.
Yellowtail / Kingfish Parasite Management Project
Ingo Ernst (firstname.lastname@example.org)
leads this research initiative funded by the Australian Research Council’s
Linkage scheme that is also supported by 3 industry partners: Yamaha Nutreco
Aquatech (Japan); Skretting Australia; South Australian Marine Finfish
Farmers Association. Monogeneans have become a particularly important
problem for aquaculture of Yellowtail in Japan and Kingfish in South Australia
and the Mediterranean and may affect culture of Seriola spp. elsewhere.
Benedenia seriolae, Heteraxine heterocerca and Zeuxapta
seriolae can severely harm production and improved disease management
is needed to enable efficient production and to ensure industry sustainability.
Aims of this project are to develop integrated pest management strategies
for monogenean infections of fish in sea-cage aquaculture. Research foci
include: improved knowledge of species life-cycles; comprehensive understanding
of parasite infection dynamics; strategic application of treatments; modelling
parasite populations and treatment strategies; field tests. The project
vision is: "efficient, effective & environmentally aware parasite
management strategies that allow competitive & sustainable production".
Clinton Chambers (email@example.com)
is a Research Associate on this project. Fieldwork will be done in close
cooperation with kingfish and yellowtail farmers in South Australia and
Neobenedenia species: attempts to sort out
Funded by the Australian Academy of Science, Ian visited
Mazatlán and La Paz in Mexico for 3 weeks in July 2002 with a view
to studying the morphology, biology and genetics of Neobenedenia
spp. In Mazatlán for 2 weeks, Ian worked with Dr Emma Avila-Fajer
at the Unidad de Investigación en Acuiciltura y Manejo Ambiental
in the Centro de Investigación en Alimentación y Desarolla
(CIAD) on a Neobenedenia sp. from the bullseye puffer, Sphoeroides
annulatus (Tetraodontidae). Juvenile puffers in experimental culture
can be heavily infected and present an ideal worm culture for study. Many
observations and collections were made and work is in progress to distil
the discoveries. While at CIAD, Ian also contributed a seminar, a lecture
and a practical session about Helminths and Monogenea to students attending
a course entitled Las Enfermedades de los Peces.
La Paz, Ian spent 2 productive days with Roxana Bertha Inohuye Rivera
and Juan Carlos Pérez Urbiola at the Centro de Investigaciónes
Biológicas del Noroeste (CIBNOR) touring fish culture facilities
(pictured right), discussing parasite problems (disease and identity issues)
and planning research collaborations on different aspects of the Neobenedenia
conundrum from wild and cultured hosts. A 3 day visit to the Departamento
de Biología Marina at the Universidad Autónoma de Baja California
Sur, La Paz for collaboration with Maria del Carmen Gómez del
Prado Rosas on some monocotylid and capsalid parasites from nearby
fishes was also productive. Ian’s experiences in Mexico were highly enjoyable,
very useful and all concerned are keen for collaboration to continue.
Taxonomy, biology & ecology of monocotylid monogeneans
Leslie and Ian are approximately halfway through this
project funded for 2001-03 by the Australian Research Council. Every 3
months, 10 juvenile giant shovelnose rays (Rhinobatos typus) are
collected during visits to Heron Island at the southern tip of the Great
Barrier Reef. Tavis Anderson (now at Rutgers University, New Jersey)
and Vanessa Glennon (University of Adelaide) have been research
assistants for this project. Our aim, using a whole organism approach
combining field studies and laboratory experiments, is to examine distributions
of 3 species from the gills and 1 species from nasal tissue, to provide
new perspectives on the relative importance of season, parasite age and
mate finding that may shape parasite distributions. Allied to this project
are continuing studies on: biodiversity of monogeneans from elasmobranchs,
with collections from South Australia, Queensland, Tasmania, Northern
Territory and also Borneo (see below); biology of monocotylids, especially
egg hatching strategies; identity of problem monogeneans on elasmobranchs
in public aquaria, including treatment methods; genetic studies using
molecular techniques for phylogenetic and population studies.
Studies on bioadhesives secreted by monogeneans
Together with Dr Bronwen Cribb (University
of Queensland, Brisbane, Australia), Ian continues research embracing
live studies, light microscopy and electron microscopy to study the remarkable
adhesives secreted by many monogeneans from anterior organs. This project,
funded by the Australian Research Council, aims to characterise the various
secretory bodies produced by monogeneans in different families and to
determine how these bodies interact to generate instant attachment and
detachment to the epidermis of their fish hosts.
Survey of metazoan parasites from elasmobranchs in Malaysian Borneo
and Leslie are also part of an international team collaborating with Professor
Janine Caira (University of Connecticut), Dr Kirsten Jensen
(American Museum of Natural History, New York), Dr Peter Last,
Dr John Stevens pictured right (CSIRO Division of Marine Research,
Hobart, Tasmania) and Dr Gavin Naylor (Iowa State University) to
survey the sharks and rays of Malaysian Borneo and their metazoan parasites.
This project is funded by the National Science Foundation and involves
numerous other parasitology specialists scattered across the globe. From
mid-May to early July 2002, the team covered the breadth of Sarawak and
much of Sabah investigating local catches at fish markets, small villages,
local fishers and by cooperation with local fisheries departments. It
was especially instructive for the parasitologists to tour with the fish
experts (which also included Gus Yearsley from Hobart). Not only
are there many unrecorded parasites out there, but there are also numerous
new hosts! The team reassembles next year to focus on locations that were

The Department of Helminthology of the Oswaldo Cruz
Institute,FIOCRUZ, Rio de Janeiro Brazil, comprises two laboratories which
study parasites of fishes. The "Laboratory of Helminth Parasites of Fishes"
has published several papers on the taxonomy, ecology and ultrastructure
of helminth parasites of freshwater fishes from reservoirs in Parana and
Ceara State and on marine fishes from the littoral region of Rio de Janeiro
State. The group in the "Laboratory of Helminth Parasites of Vertebrates"
has been developing studies on the helminth fauna of either little known
hosts, such as the marine fish Trachipterus arawatae Clark, 1881
or other hosts, mainly sharks, that have been investigated extensively
for helminths along the Brazilian coast. For a full list of publications
from the 2 laboratories please contact Anna Kohn.

Slime-blotch Disease Epizootics/Enzootics
One of Dr Paul Bartel’s students, Eugene
E. Scerbo, Warren-Wilson College, Ashville, North Carolina, won a
First Place Award at the Collegiate Academy of the North Carolina Academy
of Science (Fosters Undergraduate Research) for the presentation "Slime
Blotch Disease among coral reef fish of the Bahamas." We had confirmed
his diagnosis of this disease in sub-sampled fishes. We have heard of
no recent outbreaks of this disease. Please send us any reports.
Dr Paul Sikkel, Murray State University, Murray,
Kentucky, returned to the Magueyes Island Marine Labs, La Parguera, PR,
in June 2002 to continue his work on gnathiids of coral-reef fishes. He
and his students are uncovering interesting aspects of the early life
history of these parasites.
Dr Niel Bruce, in a recent popular, online
article on New Zealand aegid isopods, discusses the odd case of mass attacks
by an aegid isopod on Caribbean bathers. Actually, these mass attacks
were by the aegid Monogram Isopod, Rocinela signata, on marine
biologists using SCUBA gear off the Caribbean coast of Colombia. The Monogram
Isopod is a common and ubiquitous parasite of Caribbean fishes. This event
was documented in a nice paper published by the victims of the attack.
Other reported attacks by the Monogram Isopod have involved individual
specimens. It is remarkable as the only fish-parasitic isopod that considers
humans a routine food item.
Bert and Lucy surveyed external fish-parasitic isopods
(Anilocra spp.) in the U.S. and British Virgin Islands in late
June 2002. The diversity and abundance seems reduced on the largely deteriorated
reefs from what it was 27 years ago on our last survey of these areas.
The "dark leech … often attached to the dorsal
fin of the Caribbean reef shark" Carcharhinus perezi recently
mentioned and illustrated online in Biological Profiles, Ichthyology,

We documented this leech species on the fins of this shark in a paper
8 years ago. We also know of no other leeches infecting Caribbean sharks.

of Sharpnose Puffer in the U.S. Virgin Islands (one of the sites reported)
and in the British Virgin Islands, but found no externally expressed lesions.
This fish, while not particularly abundant, appeared to be healthy. No
more cases have come to our attention. Please send us infected Sharpnose

was resolved in a paper a few years ago. We sent some records to the authors.
Unfortunately the term "sea lice," which should be reserved
for argulids, has also been, rather sloppily, applied to caligid copepods
We have isolated a potential human pathogenic fungi
from lesions of food fishes in Puerto Rico. This parasite has not previously

Danish fish parasitology has recently expanded its
web into related fish disease groups. Due to a joint grant from the Danish
Agricultural and Veterinary Research Council and the Danish Ministry of
Food, Agriculture and Fisheries, it has been possible to establish a research
network and a research school. This creates an encouraging and inspiring
atmosphere among Danish fish disease enthusiasts. The ambitious name SCOFDA
(Sustainable Control of Fish Diseases in Aquaculture) has been allocated
to the project. The two SCOFDA research entities are led by Kurt Buchmann
at the Royal Veterinary and Agricultural University (KVL) in Frederiksberg.
Colleagues from research institutions working in the field of fish parasitology,
fish immunology, fish virology, fish bacteriology and genetics are engaged
in various projects in this field. Through a number of annual meetings,
workshops and Ph.D. courses, members of the network are obtaining a more
holistic view about fish biology. This is emphasised further by incorporation
of SCOFDA into a larger Fish Biology network that can be visited at www.fishnet.dk.
It is in fact possible to fetch important inspiration from only slightly
related fields in fisheries science.
But back to basics. Specifically talking about parasitology,
Ph.D. student Jens Sigh (email@example.com)
is working on a DNA-vaccine against Ichthyophthirius multifiliis.
Ph.D. Student Thomas Lindenstrøm is engaged in the study
of cytokine expression in fish skin during Gyrodactylus infections.
Postdoc Michael E. Nielsen (firstname.lastname@example.org)
is currently involved in the description of the early development of immunity
in rainbow trout. Masters student Martin Raida (email@example.com)
participates by describing the effects of probiotic bacteria on immunity
of trout to various pathogens. In addition, in a fruitful collaboration
with Scottish and Norwegian colleagues, we have had luck obtaining EU-funding
to study the genetic basis for Gyrodactylus resistance in salmon.
Researcher Michael Dalgaard (firstname.lastname@example.org)
is working hard together with Masters students Thomas Bjerre Larsen
Steinunn Hilma Olafsdottir and Steen Jørndrup (email@example.com)
and Ph.D. student Carsten Nielsen (firstname.lastname@example.org)
to describe the susceptibility of various salmonids to infections with
different species of Gyrodactylus. These brave parasitologists
still have ambitions to unravel the mechanisms behind host specificity
in parasite-host systems (we did not put a time limit on the work). Our
experienced friend and colleague José Bresciani (email@example.com)
from the Ecology Department (Zoology section) at KVL is engaged in many
of the projects with great enthusiasm.
The network has also established a link to and cooperation
with Marianne Køie (firstname.lastname@example.org)
at the University of Copenhagen, who is seeking life cycles of marine
myxosporeans with great enthusiasm and not without success.
We are happy that a number of good friends and colleagues
from foreign laboratories have taken the time to visit our laboratory,
workshops, courses and meetings and don’t forget that the SCOFDA network
welcomes colleagues from all over the world to participate in our meetings
also in the future.
The next workshops to be held at KVL in 2003 include:
Sustainable Management of Diseases in Aquaculture, November 4-6, 2003.
The next Ph.D. course will be held at KVL in April 2003; Title: Interactions
between pathogens and fish, April 1-8, 2003
We are also pleased to announce the launch of a brand
new Master’s Degree in Parasitology at KVL. It commenced in September
2002 and is run in English, welcoming students from all over the world.
If you have your BSc you can enrol in this new Master’s degree in Parasitology.
You will be taught not only fish parasitology but also veterinary parasitology,
human parasitology and wild life parasitology. Special courses include
Systematic Parasitology, Zoonotic Parasites, Parasitological Methods and
Ecological Parasitology. Visit us at www.kvl.dk.

It is a great pleasure to be the Korean representative
for Ichthyoparasitology Newsletter. We spent a very hot summer this year
enjoying World Cup Soccer and ichthyoparasitologists also spent a busy
time in research this year.
Rockfish, Sebastes schlegeli, culture in Korea
has been seriously affected by Microcotyle sebastis infection for
many years. Prof. Ki-Hong Kim, at Pukyoung National University,
has interests in developing drugs for M. sebastis infection, and
showed some promising results by using anthelminthic drugs and H2
histamine receptor antagonist, simultaneously. He also published a report
on the newly discovered myxosporean parasite, Leptotheca koreana
from rockfish. One of his graduate students, Jae-Bum Cho, is working
hard on its biology and life cycle.
The protozoan infection, scuticociliatosis, has also
caused damage to Olive flounder, Paralichthys olivaceus, culture
in Korea. Dr. Bo-Young Jee, in the National Fisheries Research
& Development Institute, has been working extensively with this ciliate,
and he identified the causative agent of scuticociliatosis as Uronema

for treating the infection, but some farms are still suffering from the
Dr. Jeong-Ho Kim,
in RNL Life Science Company Co. Ltd., has been working with the parasites
of imported tropical fish, and reported several new parasites which had
not been recorded in Korea. Camallanus cotti is thought to cause
the most serious problem in tropical fish culture in Korea. Hobbyists
also complain of sudden fish deaths after purchasing guppies from pet
shops. Some chemicals, including anthelminthic drugs for humans, are being
used customarily for the treatment at the present time.

This year parasitologists in México had the
opportunity to attend the national conference on parasitology (XV Congreso
Nacional de Parasitology- CONAPAR) in September. The meeting was held
in Guanajuato, GTO, a beautiful city for a meeting, since it is one of
tourist attractions of the area. CONAPAR is the biannual meeting for the
members of the Sociedad Mexicana de Parasitología, and always is
well-attended by both investigators and their students. This year the
main theme was neurocysticercosis, a grave problem in Mexico. Roundtable
discussions and presentations included such topics as: the biology of
Taenia solium, clinical aspects of neurocysticercosis, cysticercosis
and taeniosis, and control of Taenia solium. One roundtable, "parasites
of fish and birds" (chaired by Sylvia Paz Díaz-Camacho,
Universidad Autónoma de Sinaloa, Sinaloa), was of particular interest
to ichthyoparasitologists. Topics discussed included the importance of
studies of parasites of fishes and birds, prevalence and intensity of
helminths of Mugil cephalus in Río Colorado, Baja California,
and fishes that participate in the life cycle of Gnathostoma spp.
in Sinaloa, Mexico. Oral presentations concerning helminths of fishes
were made by Griselda Pulido-Flores and Scott Monks, Universidad
Autónoma del Estado de Hidalgo (UAEH) ("Helminth parasites
of fishes in Bahía Chetumal, Quintana Roo") and Scott Monks,
Silvia Aviles-Torres, and Griselda Pulido-Flores (UAEH) ("Paratenic
hosts of the acanthocephalan Gorgorhynchoides bullocki in
Laguna Río Huach, Quintana Roo"). Poster presentations were
made by R. A. Hernández-Juárez, E. Tetetla-Rangel, Javier
Almeyda-Artigas, and Miguel A. Mosqueda-Cabrera, Laboratorio

News from various institutions
María del Carmen Gómez del Prado
(Dept. de Biología Marina, Univ.
Auto. de Baja California Sur, B.C.S.) could not attend the IX CONAPAR,
but is continuing her work with parasites of fishes of the Gulf of California.
She has a new student, Oscar Méndez, who is beginning his
Master’s thesis project on helminths of elasmobranchs.
Several parasitologists were notably absent from the
IX CONAPAR. In particular, Victor Vidal-Martínez (Lab. de Parasitología,
CINVESTAV-IPN, Merida, Yucatán) and Raúl Pineda-López
(Lab. de Parasitología, Univ. Auto. de Querétaro, Querétaro)
were unable to attend, although each sent students to represent their
Roberto Javier Almeyda-Artigas, Miguel A. Mosqueda-Cabrera
and their laboratory (Lab. de Sanidad Acuícola y Parasitología
Molecular, Univ. Auto. Metropolitana-Xochimilco, D.F.) are continuing
their work on gnathostomiasis. Many of their current projects concern
maintenance of Gnathostoma spp. in the laboratory and on verification
of life cycles in nature. Miguel says their lab should soon have the ability
to supply the various life cycle stages of the Mexican species of Gnathostoma
for laboratories wanting to do experimental work on members of the group.
This will be a big help for investigators studying such topics as immunology
who need a large number of parasites. Their lab was out in full force
for IX CONAPAR and their students presented several talks and posters.
García-Magaña, Universidad Juárez Autónoma
de Tabasco, is also studying Gnathostoma, among other helminths,
in freshwater fishes of Tabasco. She is busy building and organizing the
collection of parasites at UJAT. Serapio López-Jiménez (right)
also of UJAT, has finished his doctoral work with helminths of freshwater
fishes of Tabasco and is busy writing up his results for publication.
Investigators from the Laboratorio de Helmintología,
Instituto de Biología, UNAM, Rafael Lamothe-Argumedo, Gerardo Pérez-Ponce
de León, Virginia Léon-Regàgnon, Luis García-Prieto,
Guillermo Salgado-Maldonado, and David Osario-Sarabia were busy with various
projects but still found time to work on helminths of fishes. In addition
to publications concerning parasites of hosts other than fishes, Gerardo
Pérez-Ponce de León published a study of endohelminths of
ictalurids (Comp. Parasitol. 69:10-19) with Anindo Choudhury (from St
Norbert College, DePere, WI, but working on helminths of Mexican fishes).
Most of the other publications that originated in the Instituto concerned
hosts other than fishes.
One of the high points of the year for Scott Monks
(Lab. Sistemática Animal, Centro de Investigaciones Biológicas
Universidad Autónoma del Estado de Hidalgo, Pachuca, Hidalgo, Mexico),
and Griselda Pulido-Flores (Lab. Morfofisiología, CIB, UAEH) was
the move into their new laboratories. Each needed the space for incoming
students. María Laura Garduño-Méndez entered
the doctoral program at UAEH in July to work with Scott on aspects of
histopathology and Víctor Rafael Zárate-Ramírez
began his MS studies and will focus on the helminth biodiversity of the
freshwater fishes of the Metztitlán Reserve in Hidalgo. Shayuri
Moreno-Flores began her MS studies with Griselda and will study the
risk of zoonotic helminths for the people living in the Metztitlán
Reserve. In addition, each has an undergraduate student working on her
thesis: Kenia Magali Ortega-Sánchez, studying histopathology
with Scott and Ana Erika Gutiérrez-Cabrera (right)
studying the distribution of the introduced cestode Bothriocephalus
acheilognathi in Hidalgo. As if that wasn’t enough to keep them busy,
6 more students have asked to begin research projects in 2003 in one or
the other of the two laboratories.
Both Griselda and Scott attended the 49th Annual Meeting
of the Southwestern Association of Naturalists and presented talks titled
"Acanthocephalans of Eugerres plumieri from Bahía de
Chetumal, Quintana Roo, México" (GPF) and "Paratenic
hosts (Eucinostomus jonesi and Atherinomorus stipes) of
the acanthocephalan Gorgorhynchoides bullocki in Laguna Río
Huach, Q. Roo, México" (SM). Scott and Griselda coauthored
a publication titled "Reevaluation and emended diagnosis of Illiosentis
and I. heteracanthus (Acanthocephala: Illiosentidae)" (J.
Parasitol. 88: 365-369). Several projects focusing on helminths of freshwater
fishes in the Metztitlán Reserve have been funded and work has
begun on the survey aspects of the projects. A new addition to the CIB
is Ulises Jesús Razo Mendivil, working in the Lab. of Molecular
Systematics, who is planning to collaborate on a project with Scott when
he finishes his doctoral work in July, 2003.
Other parasitologists in Mexico were hard at work
all year, but because I was not able to speak with them at the major meetings,
they have gone unmentioned (but have not been forgotten!) here. Hopefully,
I will be able to give you an update on their work in the next newsletter.

The research group on Aquatic Parasitology of the
Department of Zoology and Entomology (University of the Free State, South
Africa) has a major project in the Okavango River and Delta in Botswana.
This project has been going on for five years now. Due to the distance
from Bloemfontein, some 2000 km, and the remoteness of the locality, we
usually go there for an extended time, with quite a major team of staff
and students, to make the most of the occasion. In 1999 we modified a
barge into a lab / kitchen / sleeping quarters and floated down the river
into the swamp (photo-right). It
was a magical time, every evening a chorus of sounds lulled (or not) you
to sleep; the nearby cough of a leopard, the giggling chatter of the wild
dogs and the incessant jaw clapping of the crocodiles as they hunted each
night around us in the river. Every morning a cacophony of birds awoke
each team member on the barge, no hope of sleeping in! The barge worked
wonderfully, even to the point of working with the microscopes while we
were under full steam! With the locals moving around in their traditional
mokoros (dug out canoes) and the odd tourist boat in that remote part
of the delta, we were a constant source of amazement to every passerby.
Our research covers the very wide field of aquatic parasitology, though
most team members concentrate on various groups of fish parasites. Some
students also collect snails as part of their study on trematode life
cycles, as well as a student studying the weird and wonderful mites of
aquatic bivalves. The impressive list of parasites is growing; the Okavango
River and Delta in Botswana boast some 82 species of fish of which we
have collected 72 so far over the last five years. This mecca for a parasitologist
always has surprises with two new species of fish described since our
previous trip last year! The parasites include a myriad of single celled
wonders, which is also the most diverse group in this system (represented
so far by 16 genera), but it doesn't stop there. Several crustaceans represented
by eight genera have already been collected, as well as a whole waggle
of worms, adult and larval stages.
This year we will be spending two months over the
Christmas period in Botswana, a full summer trip amongst anopheline mosquitoes
and heat waves. This will be a unique opportunity to study the fish and
their parasites when the water level in the river is at its lowest and
also just before the water from the Angolan highlands reach the system.
The low water level will expose sand banks with their unique fauna of
bivalves and the smallest cutest sand catlets, a massive 12 mm long in
full adult form.
A team of eight people will leave Bloemfontein, with
the students staying three weeks. After that the base team, made up of
the permanent research staff, will stay on alone until a student team
join us again the last two weeks.

Post-graduate student, Julia Korniychuk, supervised
by Albina Gaevskaya, recently defended her thesis successfully
for a PhD degree. Her thesis was entitled: "Structure and characters of
functioning of trematode, Helicometra fasciata (Rud., 1819) parasite
system in the Black Sea near-shore." Julia
confirmed the occurrence of 42 digenean species from the Black Sea fish,
including the two new species Cainocreadium flesi and Peracreadium
gibsoni. Furthermore, three genera and two species (Pseudobacciger
harengulae and Aphallus tubarium) have been recorded in the
Black Sea for the first time. The host-range was extended for 18 species.
Helicometra fasciata maritae were recorded from eight new fish
hosts. Julia investigated many fascinating aspects of the life-cycle and
ecology of H. fasciata including studies on the castration of the
intermediate short-lived mollusc host, Gibbula adriatica, by sporocysts,
population dynamics of metacercariae in Palaemon elegans shrimps
and phenotypic structure of H. fasciata maritae hemipopulations.
She also proposed a methodical approach to estimate the degree of importance
of definitive hosts for helminth parasite systems.

Two main areas of parasite research are being carried
out at CEFAS (funded by DEFRA) Weymouth Laboratory (Barrack Road, The
Nothe, Weymouth, Dorset, DT4 8UB, United Kingdom). Firstly, we are examining
the development, early pathogenesis and routes of entry by Tetracapsuloides
bryosalmonae, the causative agent of salmonid proliferative kidney
disease (PKD). We have demonstrated that the agent appears to enter the
fish via the mucus cells before being transported around the body, probably
via the circulatory system. We have recently completed a series of trials
involving grayling and salmon and preliminary results indicate that the
route of entry for the parasite appears to be same as that for rainbow
We have also been characterising myxozoan infections
in 0+ cyprinid fry using parasite morphology, in-situ hybridisation,
electron microscopy and DNA sequencing as well as histology to assess
their pathogenicity. We are currently assessing the impact of these parasites
(and others) on coarse fish populations.
As part of our life cycle investigations for the parasites
infecting cyprinids we have examined approximately 20,000 oligochaetes
for the presence of actinospores and are currently in the process of describing
the types found and their spatial and temporal distribution. Studies to
correlate 18s DNA sequence with myxospores infecting fish are still in
Parasites as indicators of environmental contamination
As part of a larger project using biomarkers for the
assessment of estuarine environments, we have examined the parasite faunas
of flounder, sand gobies and viviparous blennies to assess whether they
could be used to discriminate between contaminated and reference sites.
In combination with data on histopathological changes and other biomarkers
(EROD induction, bile metabolites, DNA adducts), analysis of parasite
data using diversity indices, infracommunity structure and multivariate
and univariate statistics has been successful in discriminating between
Tribute to Professor Boris Kuperman
Prof. Boris Kuperman
will be remembered by the scientific community as an expert in the field
of parasitology, and primarily fish parasitology. His work over three
decades in Russia was dedicated to research on platyhelminths, especially
cestodes. While the geographical coverage for Prof. Kuperman's studies
ranged from the Baltic Sea to the Far East, the principal location of
his fieldwork was the Volga River Basin. Prof. Kuperman's morphological
and functional investigations of platyhelminths in freshwater fishes were
supported by extensive data from electron microscopy and resulted in the
publication of four comprehensive monographs and more than 100 papers.
Over 20 masters and doctoral students in the field of parasitology were
mentored by Prof. Kuperman and defended their theses under his supervision.
In 1996, Boris Kuperman and his family moved to the
US, where he conducted research and lectured as an adjunct professor in
the Department of Biology, San Diego State University. His research interests
extended to include parasites of fish and invertebrates from a unique
hypersaline lake in Southern California, the Salton Sea, as well as the
study of the introduced parasites of fishes and frogs in California. In
the last six years of his life in the U.S.A., he published 11 research
papers and prepared for publication several other contributions. He participated
at seven national and international parasitological meetings, and numerous
local and regional conferences. The passing of Prof. Boris Kuperman is
a huge loss to the parasitological communities of Russia and the USA,
and to all of us.

Our primary objective is to produce an authoritative
and practical volume on diseases and disorders of finfish in cage culture.
We hope the book will also alert the industry to potential and/or emerging
disease problems in specific regions of the world, and to point out gaps
in our knowledge so as to stimulate further research. This book is designed
for aquaculturalists who are using or intend to use cage culture. It is
also useful to fish health consultants (e.g. veterinarians), microbiologists,
parasitologists, fish pathologists and managers and directors of diagnostic
laboratories. Each chapter is written by international experts who have
had personal experience or expertise on diseases and their diagnosis,
and/or solutions to problems associated with the cage culture of finfish.
The book is divided into four Parts – Part 1 is on
the cage culture system, the second and third are on diseases/disorders
in warmwater and in coldwater fish respectively. There are three chapters
in each of these Parts - one on infectious diseases in fresh water, one
on estuarine and marine diseases and one on non-infectious disorders.
Part IV is on sporadic and emerging diseases/disorders and it is to alert
the industry to potential problems.
