Temperature effects on swimming performance, energetics, and aerobic capacities of mature adult pink salmon ( Oncorhynchus gorbuscha ) compared with those of sockeye salmon ( Oncorhynchus nerka )
We assessed the prolonged swimming performance (U crit ), metabolic rate (M-dotO 2-min and M-dotO 2-max ), and oxygen cost of transport (COT) for upper Fraser River pink salmon (Oncorhynchus gorbuscha (Walbaum, 1792); 53.5 ± 0.7 cm FL) and sockeye salmon (Oncorhynchus nerka (Walbaum, 1792); 59.3 ± 0...

We assessed the prolonged swimming performance (U crit ), metabolic rate (M-dotO 2-min and M-dotO 2-max ), and oxygen cost of transport (COT) for upper Fraser River pink salmon (Oncorhynchus gorbuscha (Walbaum, 1792); 53.5 ± 0.7 cm FL) and sockeye salmon (Oncorhynchus nerka (Walbaum, 1792); 59.3 ± 0.8 cm FL) across a range of naturally occurring river temperatures using large Brett-type swim tunnel respirometers. Pink salmon were capable of similar relative critical swimming speeds (U crit ) as sockeye salmon (2.25 FL·s –1 ), but sockeye salmon swam to a higher absolute U crit (125.9 cm·s –1 ) than pink salmon (116.4 cm·s –1 ) because of their larger size. Nevertheless, three individual pink salmon (U crit-max = 173.6 cm·s –1 ) swam faster than any sockeye salmon (U crit-max = 157.0 cm·s –1 ), indicating that pink salmon are far better swimmers than has been previously assumed.
