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

New Zealand Journal of Marine and Freshwater Research, 1990
Abstract 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). In both crosses the success rate of induction of embryonic development was low and the hatched fish had poor survival.

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.

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 ...

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.

Viability of Sacramento River Winter‐Run Chinook Salmon

Conservation Biology, 1998
The winter run of chinook salmon (Oncorhynchus tshawytscha) on the Sacramento River in California (U.S.A.) was the first Pacific salmon stock to be listed under the U.S. Endangered Species Act. We describe some of the characteristics of Pacific salmon populations that require special consideration in viability analysis during development of a model ...

Plasmacytoid leukemia of chinook salmon.

Leukemia, 1997
Plasmacytoid leukemia is a common disease of seawater pen-reared chinook salmon (Oncorhynchus tshawytscha) in British Columbia, Canada, but has also been detected in wild salmon, in freshwater-reared salmon in United States, and in salmon from netpens in Chile.

Antisomatostatin-induced growth acceleration in chinook salmon (Oncorhynchus tshawytscha)

Fish Physiology and Biochemistry, 1994
Since somatostatin (SRIF) inhibits the release of growth hormone (GH), its immunoneutralization may provide an alternative to GH therapy as a means of enhancing somatic growth in fish. The present study examined the feasibility of accelerating growth in juvenile chinook salmon by means of antiSRIF administration.

Maximum Size of Chinook Salmon Consumed by Juvenile Coho Salmon

North American Journal of Fisheries Management, 1999
Abstract We evaluated predation of coho salmon Oncorhynchus kisutch on wild fall chinook salmon O. tshawytscha by conducting feeding trials in partitioned fiberglass troughs and in outdoor enclosures. Our goal was to determine the maximum size of fall chinook salmon that juvenile coho salmon could, or would attempt to, consume.
