Abstract

size groups of hatchery reared cod (2-109 g) and three size groups of wildcod (447-2213 g) were reared at a range of constant temperatures. All groups were fed to satiation, the hatchery fish on dry feed and the wild fish on capelin and shrimp, The optimal temperature for growth decreased linearlywith fish weight on a log scale from 17 degreesC for 2 g fish to 7 degreesC for 2000 g fish. Similarly, the optimal temperature for feed conversion decreased with fish weight. from 15 degreesC fur 7 g fish to 7 degreesC for 2000 g fish. Growth rate at optimal temperature declined linearly with fishweight on a log-log scale from 5.8 to 0.36% per day for 2 and 2000 g cod, respectively.
