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.
