Food intake, conversion and swimming activity in the air-breathing catfish Heteropneustes fossilis

Pandian & Vivekanandan (1976) and Vivekanandan ([976), who considered feeding rate and conversion efficiency estimates as parameters for assessing metabolic rates and efficiencies. observed that the obligatory airbreathing fish Opiliocepha/us slriatus, reared in aquaria containing different depths of water, swam longer or shorter distance to exhange atmospheric air; such a design of experiment permitted them to measure food intake. growth and sustained active metabolism on a long term basis
