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.
