| Abstract: | Reproduction of the African catfish under hatchery conditions depends on the artificial induction of egg maturation and ovulation. In this study the combination of pimozide/LHRHa as ovulation-inducing substance has been evaluated. At a dosage, given as one single injection, of 5 mg pimozide + 0.05 mg LHRHa per kilogram body weight, 100% ovulation was achieved. Most of the eggs, collected after stripping, could be fertilized and hatched normally. |
