Inheritance of Alpha-Glycerophosphate Dehydrogenase in the Pink Salmon, ONCORHYNCHUS GORBUSCHA (Walbaum).

Genetic crosses of alpha-glycerophosphate dehydrogenase (alpha-GPDH) phenotypes in the pink salmon, Oncorhynchus gorbuscha (Walbaum), reveal that this enzyme is encoded by a single locus with two codominant alleles (Slow and Fast). The significance of single gene control of alpha-GPDH is discussed in relation to the purported tetraploid nature of the salmonids.

Stabilizing oils from smoked pink salmon (Oncorhynchus gorbuscha).

Smoking of meats and fish is one of the earliest preservation technologies developed by humans. In this study, the smoking process was evaluated as a method for reducing oxidation of pink salmon (Oncorhynchus gorbuscha) oils and also maintaining the quality of oil in aged fish prior to oil extraction. Salmon heads that were subjected to high temperatures (95 degrees C) during smoking unexpected...

Genetic linkage mapping of allozyme loci in even- and odd-year pink salmon (Oncorhynchus gorbuscha).

We constructed genetic linkage maps of allozyme loci in even- and odd-year pink salmon (Oncorhynchus gorbuscha), using the total of 320 families (each female was crossed with two different males, and 80 females and 160 males were used for each of even year and odd year). The maps include eight linkage groups involving 22 loci. We observed substantial variation in recombination frequencies among...

Cytochrome P4501A induction in oil-exposed pink salmon Oncorhynchus gorbuscha embryos predicts reduced survival potential

Cytochrome P4501A (CYP1A) induction in pink salmon Oncorhynchus gorbuscha embryos exposed to crude oil is linked to adverse effects at cellular, organism and population levels, and can be used to predict these responses. When combined with the results of an experiment designed to examine CYP1A induction during embryonic stages and growth after emergence, results from a series of experiments spa...

Pink salmon (Oncorhynchus gorbuscha) osmoregulatory development plays a key role in sea louse (Lepeophtheirus salmonis) tolerance

Sea lice (Lepeophtheirus salmonis) of fish-farm origin have been implicated in reducing populations of pink salmon (Oncorhynchus gorbuscha) in British Columbia’s Broughton Archipelago. Owing to the physically disruptive nature of louse attachment to fish skin in a hyperosmotic environment, we hypothesize that the impacts on fish performance are ionoregulatory in origin. Therefore, ionoregulator...
