SEX CHROMOSOMES IN THE SOCKEYE SALMON: A Y-AUTOSOME FUSION
Canadian Journal of Genetics and Cytology, 1978Chromosomes of 21 sockeye salmon [Oncorhynchus nerka (Walbaum)] from three locations in Washington state were examined. All males had 57 chromosomes, while all females had 58 chromosomes. Both sexes had 104 chromosome arms. It appears that in males of this species the Y chromosome and an autosome have fused to form a metacentric chromosome.

Liver arginase activity in the sockeye salmon, Oncorhynchus nerka
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971Abstract 1. 1. Liver arginase levels in adult sockeye salmon show characteristics similar to that of higher animals. 2. 2. Results show that sockeye liver arginase has a pH optimum of 9·5, is partially dependent on Mn2+ ions and has a temperature optimum of 45°C.

Migratory Behavior of Sockeye Salmon Fry and Smolts
Journal of the Fisheries Research Board of Canada, 1967Considerable new data on the characteristics of sockeye fry and smolt migrations, direct underwater observations of migrating smolts, and a review of the literature are presented here with a synthesis, evaluation, and interpretation of possible survival advantages of these phenomena.

Activity and behaviour in spawning sockeye salmon
2009Total energy expenditures and muscle activity have been measured in spawning salmon but behaviour specific energy-use has never been been measured directly. This research used electromyogram (EMG) telemetry, combined with behaviour observations to assess activity levels and estimate relative energy use during spawning in sockeye salmon, Oncorhynchus ...

Pressure in the early life history of sockeye salmon.
2011Young sockeye salmon (Oncorhynchus nerka) may occupy the epilimnion, thermocline or hypolimnion during lacustrine residence and may make extensive vertical migrations. Residence and migration over a range of pressure presents fish with certain physiological problems. Sockeye salmon meet these problems by adaptation, compromise and fortuity.
