Panel Discussion: A National and International Overview of Aquatic Animal Medicine
Dr. D.D. Hammond1, Curator – Veterinarian; Dr. D.O. Beusse2, Veterinarian; Dr. Nicholas R. Hall3, Director and Professor Immunology; Dr. Greenwood4; Dr. Hoey5
Notes
Dr. Beusse
Disease Prevention
Vaccinate against Erysipelas and Clostridium. Use Diethyl carbamazine to prevent heartworms in the elephant seal. Monitor the environment and culture for pathogens. Isolate sick and new animals. Shipment should be rapid and without stress. Drugs are used in shipment of fish and sharks to decrease stress.
Diagnosis
Observation by trained personnel will reveal clinical signs. Proper restraint is needed for physical examination. Clinical pathology results such as hematology, blood chemistry and urinalysis should be rapidly obtained. Radiology has limited usefulness.
Treatment
Treat according to the diagnosis. The treatment route can be topical, parenteral or oral. Nursing is 95% of medicine. A change of water such as placing a marine mammal in fresh water can give results. Isolation pools should be available where it is easy to handle sick animals. Adequate restraint in the form of a squeeze cage, net or chemical dosage is important.
Beached Animals
Dead animals should be post-mortemed. One should check for the presence of insecticides and other toxic substances.
Education and Research
There is a triangle formed by research personnel, the university and the oceanarium. Elective marine mammal programs are needed, i.e., Cornell has an elective in this area for senior year veterinary students.
Dr. Hall
Normals need to be defined before disease can be understood.
Research is especially needed in areas such as the immune system, histology and physiologic mechanisms. Dr. Hall suggests one should transport the research laboratories to where marine mammals are abundant, available and easy to maintain, such as across international boundaries in the Caribbean.
Dr. Greenwood
In the United Kingdom
-
Dr. Ron Roberts does research in salmonid and whitefish culture.
-
The Department of Agriculture has a marine fish research laboratory.
-
Many veterinarians are interested in zoology.
Fish Publications
-
A New Journal of Fish Diseases
-
Journal of Fish Biology - produced by Huntington Research Center
-
Fish Pathology - Dr. Roberts
Seabird Research
-
Holland and the UK are doing research on bird kills related to oil, oil products and to toxins
-
Scandinavia - Hg and PCB levels are being monitored.
Marine Mammals
Legislation
-
Cetaceans are royal animals and belong to the Crown. The Crown has handed stranded animals over to the Natural History Museum.
-
Seals are covered by the Seal Act. Controlled harvest of Gray, Harbor and Mediterranean Monk seals is allowed.
Research
The Journal of Aquatic Mammals is published by a non-profit foundation.
Dr. Hoey - Aquatic
Animals in Canada
There is a Canadian Association of zoos, parks and aquaria.
Aquaculture
-
on the Prairies, mainly in Manitoba.
-
there are some small farms on Vancouver Island due to a government funded aquaculture program for the native Indian.
There is a new zoo in Vancouver.
Federal Government research on killer whales has ceased for reasons of austerity.
