Surfacing activity and food utllization in a tropical air-breathing fish exposed to different temperatures

Abstract

In tropical countries like India, \vhere availability of freshwater is limited , air-breathing fishes may be chosen for aquaculture, as they thrive in shallow waters deficient in oxygen. However, the advantageous air-breathing habit of these fishes and the consequent need to surface more or less at regular intervals may impose a considerable drain of energy, which otherwise could have been channelled into fish production
