Laboratory in 1950. Director of that Institute during initial phases at the College of Fisheries 1950-1953,
and at Cook, Washington 1953-1975. Guest lecturer in Nutrition and Biochemistry 1958-1963.
Affiliate Professor, University of Oregon Medical school 1965-1970. Affiliate Professor, University
of Washington, College of Fisheries 1960-1978. Visiting Professor, Marine Science Institute, University
of Texas 1979; Senior Scientist in Nutrition for U.S. Fish and Wildlife Service 1975-1978, Senior Scientist in Nutrition Emeritus
for USFSW; Professor in Nutrition, University of Washington 1975-1992; Professor Emeritus in Nutrition 1992-present’
President, Fisheries Development Technology, Inc 1985-1995;; President, Halver Corporation 1992-present.In the above position he has traveled to many developing countries of the world and has been involved in major research,
development, and training programs for a number of national and international agencies.
Notable Achievements:Work has been devoted to elucidation
of basic nutritional requirements of fishes for vitamins, amino acids, essential fatty acids, and carbohydrate sources.
Made substantial contributions in the field of oncology with fish as the experimental animal, demonstrating the sensitivity
of Rainbow trout juveniles to adventitious feed toxins and more specifically on the role of mycotoxins, aflatoxin B1 and G1
as primary or secondary factors for trout hepatomagenesis. Extensive
work also demonstrated vitamin and amino test diets and experimental techniques to determine qualitative and quantitative
vitamin and amino acid requirements of fish. He developed the standard vitamin test salmonid diet (H440)
which has been adapted and used on many other fish species for nutrition work. Techniques were also developed
to identify factors and methods for physiological assessment of state for smoltification. Ascorbate-2-sulfate
(vitamin C2) was discovered in trout and proved to be a storage form of stable vitamin c for fish and pathways for vitamers
C metabolism were elucidated. Notable discoveries: (1) discovered that B12 is the anti-anemic factor in salmon, 1950(2) reference test diet for vitamins for fish (H440) 1952; (3)
classification of water-soluble vitamin requirements for salmonids, including descriptions of specific deficiency syndromes;
(4) amino acid test diet; (5) classification
of 10 indispensible amino acids for fish; (6) identification of 12 classes of chemical
compounds as carcinogens in trout; (7) demonstration that aflatoxin B1 was the primary
carcinogen for trout hepatomas; (8) isolation and identification
of L-ascorbyl-2-sulfate as a major storage form of vitamin C in tissues and L-ascorbyl-2-sulfohydrolaze as modulator for circulating
C levels in blood and tissues; (9) role of selenium in stress; (10) role of omega-3 fatty acids in cell membrane structure; (11) role of omega-3
fatty acid deficiency and zinc metabolism in brain (early Alzheimer’s disease). Published over 240 peer-reviewed scientific papers on nutrition, toxicology, and metabolism .
National Activities:Designed, constructed, equipped, and staffed
the Western Fish Nutrition Laboratory; US Fish & Wildlife Service 1950-1968
Implemented programs in Proteins, Carbohydrates, lipids, Vitamins, and Mineral nutrition plus enzymology and intermediary
metabolism, together with applied nutrition and utilized capability for needs of the Western US area, professional and technical
staff were recruited and trained for disciplines needed. Basic nutritional requirements of salmonids were defined for management
of fishery resources. Designed,
constructed, and staffed an applied fish nutrition and diet testing laboratory for the US Fish & Wildlife service; Hagerman,
Idaho 1958-1975 (currently the University of Idaho Fish Culture Experiment Station)
Closely coordinated programs developed between basic and applied fish nutrition and diet testing facilities and national
programs yielding data necessary for operating national fish hatcheries and national fishery research missions. Coordinated national and cooperating international fishery
research and development programs 1975-1978. in fish nutrition, diet
development, diet testing, diet formulations, and quality control as Senior Scientist in Fish Nutrition; US Dept of the Interior.
Developed Fish Nutrition and Fish Feed Technology
program at the University of Washington 1978-1992.
Program courses were incorporated into the school of fisheries, University of Washington curriculum. Over
90 students from 53 countries took the 8 International intensive short courses. Developed
graduate program in marine Sciences for the University of Texas 1979.
Developed a program of Fish Nutrition courses for the Marine sciences Laboratory, Port Aransas, Texas. National Research Council, Reviewed fisheries programs
of the Committee on Animal Nutrition 1979-1983. Represented the Fisheries component on the National Research Council, Board
on Agriculture and Renewable Resources 1980-1981.Supervised and completed study on
Impacts of Agricultural Trends on Fish and Wildlife habitat for the National Research Council 981-1982. A
summary of 70 experts on agricultural trends, and as assessment by 50 experts in fish and wildlife of these trends on habitat..
Served on numerous committees and subcommittees of the National research Council 1960-1080. Organized
several national and international symposia; led several workshops in fish nutrition and aquaculture development.
Participant in numerous study tours and scientific conferences on the role of nutrition, diet, and feed technology
on fishery production. Consultant for several national and international institutions.National Academy of Science,
