NOCARDIOSIS IN CHINOOK SALMON

Journal of Wildlife Diseases, 1974
Granulomatous oral masses were observed in two Chinook salmon (Oncorhyncus tschwytscha) smolts with systemic nocardiosis. Gross and histopathological lesions are described indicating the proliferative inflammatory nature of this diesase.

Toxicity of organic selenium in the diet to chinook salmon

Environmental Toxicology and Chemistry, 1990
Abstract The toxicity of two organoselenium diets was evaluated in 90- to 120-d partial life cycle tests with two life stages of chinook salmon (Oncorhynchus tshawytscha Walbaum). One of the diets contained fish meal made from high-selenium mosquitofish (Gambusia affinis Baird and Girard) collected from the selenium-laden San Luis Drain,

Selective Breeding of Chinook Salmon

Transactions of the American Fisheries Society, 1961
Abstract Selective breeding of plants and animals has been carried on for hundreds of years. Few attempts, however, have been made to breed salmon that have characteristics which would better fit the fish for the needs of modern salmon management. Experiments started in 1949 at the University of Washington to develop a selected stock of chinook salmon (

Assimilation Efficiency of PBDE Congeners in Chinook Salmon

Environmental Science & Technology, 2015
Polybrominated diphenyl ether (PBDE) flame retardants are environmental contaminants that can accumulate in biota. PBDE accumulation in an organism depends on exposure, assimilation efficiency, and elimination/metabolism. Net assimilation efficiency represents the fraction of the contaminant that is retained in the organism after exposure.

Attempts to induce gynogenetic chinook salmon by chinook‐sockeye and chinook‐brown trout crosses

New Zealand Journal of Marine and Freshwater Research, 1990
Attempts were made to induce gynogenesis in bisexual chinook salmon ( Oncorhynchus tshawytscha ) by insemination of chinook eggs with sperms from either sockeye salmon ( O. nerka ) or brown trout ( Salmo trutta ).

Penicillin residues in treated Chinook salmon

Food Research International, 1994
Abstract Muscle tissue concentrations of penicillin-G (pen-G) were measured in different groups of Chinook salmon on different days using an HPLC assay. Following oral administration of antimicrobial by gastric lavage for 10 days, measurable concentrations declined rapidly from a range of 0·05–10·58 μg/gm of muscle tissue on the first day following ...

Evaluation of Salmon Flesh and Salmon Viscera in the Diet of Chinook Salmon Fingerlings

Transactions of the American Fisheries Society, 1945
Abstract The addition of salmon flesh and salmon viscera to a diet for chinook salmon fingerlings produced growth equal to that resulting from all-meat diets. The cost of production was reduced considerably. Salmon flesh did not prevent the appearance of an anemic condition and therefore is considered deficient in the anti-anemia factor.

Phenylhydrazine-induced anemia in chinook salmon

Toxicology and Applied Pharmacology, 1971
Abstract Single injections of phenylhydrazine (12.5 μg/g body weight) produced severe hemolytic anemia in chinook salmon (Oncorhynchus tshawytscha). Within 10 days erythrocyte counts, hemoglobin concentrations, and hematocrits were reduced to 1–5% of normal.
