Abstract: | Standard metabolic rate ( R s) at 2°C of eight East Siberian cod Arctogadus borisovi , caught in West Greenland, body mass of 601.5 ± 147.6 g (mean ± s.D.), was 40.9 ± 5.9 mg O2 kg-1 h-1 and 59.0 ± 6.6mg O2 kg-1 h-1 when extrapolated to a standardized 100 g fish. R s was compared with three other Gadidae, to test the theory of metabolic cold adaptation (MCA). There was no evidence of MCA in the family. |
