Suppression by dexamethasone of interrenal activity in adult sockeye salmon (Oncorhynchus nerka)
General and Comparative Endocrinology, 1969Abstract Dexamethasone injected intraperitoneally as a single dose of 1 mg/kg of body weight suppressed cortisol secretion in response to stress in sexually maturing sockeye salmon. The full effect of a single dose was still evident after 5 and 6 days in most fish and in many fish after 12 days.

HISTOLOGY AND HISTOCHEMISTRY OF THE PINEAL ORGAN IN THE SOCKEYE SALMON, ONCORHYNCHUS NERKA WALBAUM
Canadian Journal of Zoology, 1967The morphohistology and some histochemical aspects of the pineal organ in the sockeye salmon were studied. The distal part of the organ lies in a pineal fossa in the cranial roof. Photosensory cells and two kinds of ependymal supporting cells are present throughout its epithelium, which is entirely devoid of either melanin or lipofuchsin.

The mate-guarding behaviour of male kokanee oncorhynchus nerka
Behaviour, 2002AbstractThe 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.

The influence of temperature on sex determination in sockeye salmon Oncorhynchus nerka
Aquaculture, 2004Thermolability in phenotypic expression of sex was examined in hime salmon, a land-locked type of sockeye salmon Oncorhynchus nerka, which is a commercially valuable species in cold-water lakes of Japan and is expected to have good potential for aquaculture. Eyed-eggs or alevins of genetically all-female fish were subjected to high temperature.

Photoperiodic activity changes in juvenile sockeye salmon (Oncorhynchus nerka)
Canadian Journal of Zoology, 1971Spontaneous locomotor activity was studied in juvenile sockeye salmon under controlled environmental conditions (LD 9.5:14.5 or 12:12; 5 °C; 0.1–34.4 lux). Siblings were hatched in activity chambers and swimming movements were monitored with an ultrasonic system for 11 months.

Conservation genomics of kokanee (Oncorhynchus nerka) at their northern range periphery
2021Freshwater fisheries are important natural resources, yet a vast majority are threatened by anthropogenic stressors. Accurate baseline information on stock diversity, population history and hatchery representation are required for implementing effective conservation and management strategies for mitigating declines.
