Notes on the energy metabolism of the cod (Gadus callarias L.) and the coalfish (Gadus virens L.) in relation to body size

Abstract

The present work on the oxygen consumption in the cod and the coalfish 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. (Figs. 1, 2, 3 and 4). The oxygen consumption under standard condition shows that there is a clear linear regression between the two variables 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. (Fig. 5).
