Oxygen uptake in relation to body weight of cirrhinus mrigala (Ham)

Oxygen uptake in relatiobn to body weight of Cirrhiness mrigala was observed using a cylindrical glass respiro meter. The oxygen consumption of controlled fish increased from 2.124 ± 0.13μ5.499 ± 0.53 ml O2/h with an increase in body weight from 14.25 ± 1.42-56.50 ± 4.93 g showed a reduction (P < 0.001) of about 43% in 3 h and 39% in 24 h anaesthetization of Benzocaine respectively. The information is useful in calculation of oxygen uptake in relation to body weight of this fish for their live transportation and other experimental purpose.
