Abstract: Initial feeding and growth were studied in larval catfish Parasilurus asotus L.. The first feeding occurred at a feeding rate of 22% at six days post hatching at a water temperature of 18～21℃; yolk sac was exhausted in 8 d-old larvae which fed at a maximal feeding rate of 74% at the same water temperature; the transition from endogenous to exogenous nutrition appeared in 6～8 d-old larvae under the same water temperature; the point-of-no-return (PNR) was 9～10 days in the larvae. The larvae did not feed very well although they started to feed minced fish and salmons fodder at 14 days post hatching, whereas at 19 days post hatching, they feed fodders such as water fleas, and blood worms. Growth in the larvae increased with increase in water temperature within 22～28℃,the optimal water temperature.
