Abstract
Different species of carp fishes have different rates of oxygen consumption which varies with the change in temperature. Oxygen consumption studies were carried out on fingerlings (seed) of Labeo rohita, Cirrhina mrigala, Catla catla, Hypophthalmicthys molitrix and Ctenopharyngiodon idella at four different temperatures i.e., 15, 20, 25, 30°C in laboratory conditions. Labeo rohita seems to be the most tolerant species having highest oxygen consumption rates and better survival at low available oxygen concentration in water. Catla catla (at 15 and 30°C) and Hypophthalmicthys molitrix (at 20°C and 25°C) are least tolerant species with highest oxygen consumption rates. Rate of oxygen consumption is greater in Labeo rohita at 15, 20 and 25°C but highest in Cirrhina mrigala at 30°C. Labeo rohita seems to be the most tolerant species having highest oxygen consumption rates and better survival at low available oxygen concentration in water. Ctenopharyngiodon idella and Cirrhina mrigala are moderately tolerant species among the fish species under study.
