Corroboration of a Bioenergetics Model for Sockeye Salmon
Transactions of the American Fisheries Society, 1989Abstract We constructed a bioenergetics model for sockeye salmon Oncorhynchus nerka and evaluated its sensitivity to parameter error. When used to predict annual growth, the model was most sensitive, in declining order of importance. to changes in the intercept of the dependence of consumption on body weight, the proportion of maximum consumption, the ...

The Rivers Inlet Sockeye Salmon
Journal of the Fisheries Research Board of Canada, 1958The Rivers Inlet sockeye catch has averaged about 1 million fish per year, over 45 years. These are from smolts produced in a cold, deep lake, only 30 square miles in extent, and most of it heavily silted by glacial tributaries. The water has only a moderate lime content and its reaction is neutral or very slightly acid.

The Demise of Owikeno Lake Sockeye Salmon
North American Journal of Fisheries Management, 2001Abstract A persistent period of low abundance in what was once the second largest fishery for sockeye salmon Oncorhynchus nerka in British Columbia has kept the Rivers Inlet fishery closed since 1996. Initial speculation about the cause of the decline focused on factors such as reduced egg-to-fry survival, declining quantity and quality of spawning ...

Sounding Response of the Kokanee and Sockeye Salmon
Journal of the Fisheries Research Board of Canada, 1968When frightened, sockeye and kokanee salmon dive into deeper waters. This is termed the "sounding response."The sounding response in these fish is accompanied by the expulsion of gas from the swimbladder via the pneumatic duct. This gas loss is active and results from the contraction of the circular muscle fibers in the wall of the swimbladder.Gas loss

Hemoglobins of the sockeye salmon, Oncorhynchus nerka
Comparative Biochemistry and Physiology Part A: Physiology, 1988Abstract 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.

Magnetic field detection in sockeye salmon
Journal of Experimental Zoology, 1981AbstractPrevious research has indicated that lake‐migrating sockeye salmon fry have compass directional preferences, cued in part by magnetic fields. This paper reports the results of experiments designed to compare the magnetosensory system of salmon with those of other organisms.

Harvesting wellness with Okanagan sockeye salmon
2020Prior to colonization the Syilx Okanagan people were healthy and strong, by honouring reciprocal relationships with salmon and all living things. Colonization contributed to a loss of salmon abundance that is now being restored by the Syilx Okanagan Nation.

Dynamic in-lake spawning migrations by female sockeye salmon
Ecology of Freshwater Fish, 2007Abstract – Precise homing by salmon to natal habitats is considered the primary mechanism in the evolution of population‐specific traits, yet few studies have focused on this final phase of their spawning migration. We radio tagged 157 female sockeye salmon (Oncorhynchus nerka) as they entered Lake Clark, Alaska, and tracked them every 1–10 days to ...

Effect of introducing a competitor on cyclic dominance of sockeye salmon
Journal of Theoretical Biology, 2014We study the effects of introducing a competing species into a 3-species model for the population dynamics of sockeye salmon, thereby converting a food chain into a diamond module. We find that this often leads to the disappearance of the 4-year oscillation of sockeye salmon known as cyclic dominance when parameters are chosen such that all four ...

Retinal projections in sockeye salmon smolts (Oncorhynchus nerka)
Cell and Tissue Research, 1988The 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 ...
