Brain aging phenomena in migrating sockeye salmon Oncorhynchus nerka nerka

Journal of Neural Transmission, 2005
Aging, a process occurring in all vertebrates, is closely related to a loss in physical and functional abilities. There is widespread interest in clarifying the relevance of environmental, metabolic, and genetic factors for vertebrate aging. In the Pacific salmon a dramatic example of aging is known.

Oust the louse: leaping behaviour removes sea lice from wild juvenile sockeye salmon Oncorhynchus nerka.

Journal of Fish Biology, 2018
We conducted a manipulative field experiment to determine whether the leaping behaviour of wild juvenile sockeye salmon Oncorhynchus nerka dislodges ectoparasitic sea lice Caligus clemensi and Lepeophtheirus salmonis by comparing sea-lice abundances ...

Sexual Maturation in Kokanee Oncorhynchus nerka

Northwest Science, 2008
We used observational and experimental approaches to obtain information on factors affecting the timing of maturation of kokanee Oncorhynchus nerka, a semelparous, landlocked salmon. Gonadal staging criteria were developed and applied to three kokanee populations in Idaho lakes and reservoirs.

Retinal projections in sockeye salmon smolts (Oncorhynchus nerka)

Cell and Tissue Research, 1988
The retinal projections in 2-year-old salmon smolt (Oncorhynchus nerka) are significantly different from those observed in other teleosts examined to date in that the projections are more extensive. Very noticeable are extensive projections to most of the dorsal thalamus, to all layers of the optic tectum, and into the periaqueductal gray of the torus ...

Allozyme variability of Oncorhynchus nerka in Japan

Ichthyological Research, 2000
We examined allozymic variation in 65 protein-coding loci in three samples of sockeye salmon (Oncorhynchus nerka) from Hokkaide, and Honshu, Japan, Over-all, six variable loci were seen and each of the three samples was variable at 3–5 loci. Two loci,mAH-1,2* andALAT*, were variable at the P0,95 level. Average heterozygosity ranged from 0.012 to 0.013,

Hemoglobins of the sockeye salmon, Oncorhynchus nerka

Comparative Biochemistry and Physiology Part A: Physiology, 1988
Abstract 1. 1. Vertical starch-gel electrophoresis at pH8.6 revealed hemoglobin multiplicity with several distinct cathodal and anodal hemoglobin components. 2. 2. Cathodal hemoglobin components exhibited a higher oxygen affinity than the anodal hemoglobin components. 3. 3.

cDNA for Ribosomal Protein S2 in Sockeye Salmon, Oncorhynchus nerka

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997
We isolated a cDNA encoding ribosomal protein S2 in sockeye salmon, Oncorhynchus nerka, using a reverse transcriptase-polymerase chain reaction (RT-PCR) method. The cDNA encoding ribosomal protein S2 is composed of 933 nucleotides, and has a 5'-noncoding sequence of 9 bases, a 885 base open reading frame coding for a 294 amino acid polypeptide, and a ...

Postspawning survival in lacustrine sock-eyed salmon Oncorhynchus nerka Walb

Biology Bulletin, 2011
The state of gonads, age, structure of scales, and size of specimens of the resident lacustrine form of sock-eyed salmon--kokanee Onchorhynchus nerka--are analyzed. In stocked, previously fishless, lakes, there are specimens that have survived spawning and have remained active for a year or several years.
