Sažetak
Induced spawning of the spotted murrel (Channa punctatus) and catfish (Heteropneustes fossilis) was successfully carried out using ovaprim and human chorionic gonadotropin (HCG). Breeders were administered a single intramuscular injection of the hormones at varying dosages. Fecundity in C. punctatus was 3273 ± 75 for ovaprim and 1253 ± 126 for HCG, whereas in H. fossilis it was 6692 ± 790 for ovaprim and 82922 ± 5432 for HCG. Successful spawning of C. punctatus was observed at 0.3 and 0.5 ml/kg body mass for ovaprim and at 2000 and 3000 IU/ kg body mass for HCG. For H. fossilis successful spawning was observed at 0.3, 0.5 and 0.7 ml/kg body mass for ovaprim and 1000, 2000, and 3000 IU/kg body mass for HCG.
