Abstract

This study showed that average number of eggs produced by the Anabas testudineus female using LHRHa hormone (2773 eggs in LHRHa; 393 eggs in SGnRHa) were significantly (P < 0.05) higher than those in the SGnRHa hormone group. However, the diameters of eggs were smaller using LHRHa hormone (0.87mm in LHRHa; 1.04 mm in SGnRHa). No significant difference was found in egg fertilization rates irrespective of the treatment. The latency period of the A. testudineus was 1 h shorter when using LHRHa. First cleavage occurred at 2.30 h after the egg fertilization. The eggs completed the 128-cell division within 4 h after fertilization and entered the early gastrula stage at 6 h. The embryonic body was formed at 12 h and the fish larvae hatched at 17 – 18 h. The larvae entered the juvenile stage in 16 days and reached maturation in 2 months. This study suggests that LHRHa was more effective than SGnRHa in climbing perch.
