Growth of invasive pink salmon (Oncorhynchus gorbuscha) at sea assessed by scale analysis [PDF]
Journal of Fish Biology, 2021 AbstractInvasive pink salmon (Oncorhynchus gorbuscha) has been present in variable, but low, numbers in Norwegian waters since c. 1960, but beginning in 2017 their numbers have exploded in rivers in northern Norway, with considerable numbers also recorded in rivers in southern Norway and other countries bordering the North Atlantic.

Regularities of reproduction for pink salmon Oncorhynchus gorbuscha from the Iska River
Известия ТИНРО, 2018 Reasons for rapid rise of pink salmon landings in the Sakhalin Bay (Okhotsk Sea) in the early 21 century are analyzed. Dependence of its juveniles and adults numbers on the number of their parents is well described with Ricker equation, and the ...

Evidence of Olfactory Imprinting at an Early Life Stage in Pink Salmon (Oncorhynchus gorbuscha) [PDF]
Scientific Reports, 2016 AbstractPacific salmon (Oncorhynchus spp.) navigate towards spawning grounds using olfactory cues they imprinted on as juveniles. The timing at which imprinting occurs has been studied extensively, and there is strong evidence that salmon imprint on their natal water during the parr-smolt transformation (PST).

Aerobic scope is sustained through a heatwave in juvenile Atlantic salmon (Salmo salar)
Journal of Fish Biology, EarlyView.Abstract Aquatic ectotherms are vulnerable to heatwave‐induced physiological stress, which arises from increased energy demands and reduced dissolved oxygen content in warmer waters. Understanding thermal physiology is critical for predicting how commercially and ecologically important populations could be affected by the increasing risk of rising ...
