Biogeographic Implications of Cytochrome b Sequences and Allozymes in Sockeye (Oncorhynchus nerka)

Journal of Heredity, 1995
Nucleotide sequence and restriction site analyses of the cytochrome b gene of mitochondrial DNA revealed three relatively common haplotypes among sockeye salmon (N = 80) from eight populations representing four major drainages from Kamchatka (Russia), Alaska, and British Columbia.

The mate-guarding behaviour of male kokanee oncorhynchus nerka

Behaviour, 2002
AbstractThe patterns of mate-guarding in kokanee (non-anadromous Oncorhynchus nerka) are analysed and discussed in relation to existing theory of precopulatory mate-guarding. Male salmon typically guard females prior to spawning events and aggressively exclude other males from their vicinity.

Sequence analysis of MHC class I α2 from sockeye salmon (Oncorhynchus nerka)

Fish & Shellfish Immunology, 2011
Most studies assessing adaptive MHC diversity in salmon populations have focused on the classical class II DAB or DAA loci, as these have been most amenable to single PCR amplifications due to their relatively low level of sequence divergence. Herein, we report the characterization of the classical class I UBA α2 locus based on collections taken ...

Ammonia Quotient in Sockeye Salmon (Oncorhynchus nerka)

Journal of the Fisheries Research Board of Canada, 1978
Ammonia quotients (A.Q., ratio of ammonia excreted to oxygen consumed) were computed from data on daily-fed and starved sockeye salmon (Oncorhynchus nerka). In 22-d starved salmon, where a diel pulse in oxygen consumption, but not in ammonia excretion, persisted, the A.Q. was 0.125 at the prepulse stage (0.11 in fed fish); the lowest A.Q.

ISOLATION OF 20β-DIHYDROCORTISONE FROM SOCKEYE SALMON (ONCORHYNCHUS NERKA) PLASMA

Canadian Journal of Biochemistry and Physiology, 1962
20β-Dihydrocortisone has been isolated from the peripheral plasma of spawned male and female salmon. The plasma steroid was identified by its chromatographic mobility and that of its diacetate as well as the sulphuric acid chromogen of the steroid.

Results of the introduction of the resident form of nerka Oncorhynchus nerka in Tolmachevskoe Lake (Kamchatka)

Journal of Ichthyology, 2009
Data on the present-day (2003–2007) state of the population of kokanee Oncorhynchus nerka introduced in Tolmachevskoe Lake more than 20 years ago are provided. Since the moment of introduction, the population of kokanee has underwent considerable changes: a decrease occurred in the specific rate of growth, average length and weight of fish in catches ...

Observations on saprolegniasis of adult sockeye salmon, Oncorhynchus nerka (Walbaum)

Journal of Fish Biology, 1977
Some observations on the mycology and pathology of saprolegniasis of maturing sockeye salmon are reported. Saprolegnia spp. were isolated from all lesions examined. Some isolates did not produce oogonia and could not be identified further. The other isolates have affinities to the S. diclina‐S. parasitica complex.
