  • To sexually matured feral catfish,Mystus macropterus (Bleeker),injection of domperidone (DOM),a dopamine antagonist,failed to stimulate an increase in serum gonadotropin (GTH) level and failed to induce ovulation.Injection of LHRH-A alone had an effect on stimulating an increase in serum GTH levels,but resulted in a low ovulation rate.Injection of DOM plus LHRH-A resulted in significantly higher serum GTH levels than injection of LHRH-A alone,and resulted in a significantly higher ovulatory response.To sexually matured feral catfish,Leiocassis longirostris Gunther,injection of LHRH-A plus DOM had the same effect as LHRH-A plus silver carp pituitary suspension (SCPS),which had been used to induce ovulation of the bagrid catfishes for years,in inducing ovulation.Linpe method (LHRH-A plus DOM,given in single or two injections) avoided the truble of collecting and storing the pituitary and should be popularized in the artificial propagation of the bagrids in aquaculture.
