Some Notes on the Energy Metabolism of Gadus callarias and Gadus virens in Relation to Body Size

Abstract

The present work of oxygen consumption in Gadus callarias and Gadus virens shows that there is a connection between the body size and the acclimation time required for reaching a "normal" level of metabolism after being transferred to another aquarium (fig. : 1, 2, 3 & 4). The oxygen consumption under standard condition shows that there is a clear linear regression between the two variable used. However, the significant coefficient does not exclude the possibility of a difference in oxygen consumption in relation to the weight between small fish and bigger ones.
