Abstract
Five combinations of human chorionic gonadotropin (hCG) dose and five latency periods were evaluated to observe the pattern of deformed larvae among the hatchlings in walking catfish, Clarias batrachus (L.). A higher percentage (7%–12%) of deformed larvae were observed at 1000, 2000, and 5000 IU · kg-1 with 14–23 h latency combinations. The results of the study indicated that 3000 IU · kg-1 with 14–23 h and 4000 IU · kg-1 with 14–17 h latency combinations were preferable to reduce the deformed larvae (4%–6%) among the hatchlings during induced spawning of the catfish.
