Shorter juvenile telomere length is associated with higher survival to spawning in migratory Atlantic salmon [PDF]
, 2017 The risk of mortality associated with a long-distance migration will depend on an animal's physiological state, as well as the prevailing ecological conditions.

The geometry of reaction norms yields insights on classical fitness functions for Great Lakes salmon. [PDF]
, 2020 Life history theory examines how characteristics of organisms, such as age and size at maturity, may vary through natural selection as evolutionary responses that optimize fitness.

Swimming behavior of emigrating Chinook Salmon smolts
PLOS ONE, 2022 Swimming behavior of Chinook Salmon (Oncorhynchus tshawytscha) smolts affects transit time, route selection and survival in complex aquatic ecosystems. Behavior quantified at the river reach and junction scale is of particular importance for route selection and predator avoidance, though few studies have developed field-based approaches for quantifying

Quinnat salmon (oncorhynchus tshawytscha) spawning in the Rangitikei river [PDF]
, 1983 The occurrence of adult quinnat salmon {Oncorhynchus tshawytscha (Walbaum)) in the Rangitikei River, North Island, New Zealand, has been confirmed on several occasions since 1922, but juvenile salmon have not previously been recorded.
