Energy Expenditure of Sockeye Salmon, Oncorhynchus nerka, During Sustained Performance
, 1973 Fingerling and adult sockeye salmon (Oncorhynchus nerka) were subjected to long periods of sustained swimming (10–20 days) in air-saturated fresh water.

Satellite-Based Time Series of Chlorophyll in Chilko Lake, British Columbia, Canada
Canadian Journal of Remote Sensing, 2019 In Canada, many northern lakes are remote and difficult to access, with limited limnological data. Satellite sensors provide widespread coverage and growing time series of data unavailable via conventional sampling, but global validation is still limited.

Brain aging phenomena in migrating sockeye salmon Oncorhynchus nerka nerka
, 2018 Aging, a process occuring 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. Looking for changes in the salmon brain, perhaps even

Effect of Finclipping on Survival of Sockeye Salmon (Oncorhynchus nerka)
, 1969 A finclip and a chemical (tetracycline) mark were applied, in similar numbers, to hatchery-reared fingerling sockeye salmon (Oncorhynchus nerka). In mark-sampling of returning adults 3 and 4 years after release from the hatchery, numerical comparison of

, 1974 The feasibility of estimating the escapement of sockeye salmon (Oncorhynchus nerka) into Lake Washington by hydroacoustics was explored during 1971. Surveys were made of large fish targets within the lake just before and after the spawning migration of ...

Effects of Kokanee Salmon (Oncorhynchus nerka) Decomposition on the Ecology of a Subalpine Stream
, 1975 The role of kokanee salmon (Oncorhynchus nerka) carcass decomposition in the nutrient cycles and energy flow of a subalpine stream was investigated during a season (1970–71) of high spawner abundance and a season (1972–73) of low spawner abundance with ...

Effects of Water Quality Parameters on Prolonged Swimming Ability of Freshwater Fishes
, 2006 The critical swimming speed (Ucrit) of rainbow trout parr (Oncorhynchus mykiss) and three life stages of Galaxias maculatus, larval (whitebait), postlarval inanga and adult inanga, were tested at temperatures from 5oC to 25oC. All fish were swum at their

Satiation Time, Appetite, and Maximum Food Intake of Sockeye Salmon (Oncorhynchus nerka)
, 1971 Three aspects of feeding relations in sockeye salmon (Oncorhynchus nerka) were studied, using Abernathy pellets. When food was presented in excess at 15 C, mean satiation time was found to be 43 ± 8 min, independent of fish size.

Diet of rainbow trout in Lake Rotoiti: an energetic perspective
, 2012 We characterised seasonal and ontogenetic changes in diet and prey energy density of rainbow trout (Oncorhynchus mykiss) in Lake Rotoiti, New Zealand, to better understand the prey requirements of trout in central North Island lakes.
