The Resistance of Cultured Young Chum and Sockeye Salmon to Temperatures Below 0 °C.

Recent efforts to establish Pacific salmon in Hudson Bay posed the question of low temperature tolerance in these species. A series of lethal temperature tests at −0.5, −1.0 and −1.5 °C. demonstrated that resistance to temperatures slightly below 0 °C. was limited. Freezing of the blood and aqueous...

Description
Summary:Recent efforts to establish Pacific salmon in Hudson Bay posed the question of low temperature tolerance in these species. A series of lethal temperature tests at −0.5, −1.0 and −1.5 °C. demonstrated that resistance to temperatures slightly below 0 °C. was limited. Freezing of the blood and aqueous humour occurred at temperatures of −1.0 and −1.5 °C.
