Comparative evaluation of different hormones on the reproductive performance of pearl spot (Etroplus suratensis)

Ezhilarasi V, Felix S and Samuel mosses TLS

Pearl spot, Etroplus suratensis were induced to spawn in captivity to assess the efficiency of two dissimilar synthetic hormones Viz.., HCG and WOVAFH under captive condition. The experiment was designed with 2 treatments and one control. The treatment brooders were injected with single dose of 0.5 ml kg-1 body weight WOVA FH and 1500 IU HCG and normal saline (0.9%) for control. For each of the hormone administered treatment, results were recorded. Spawning was observed within 24-48 h after injection. Hatching of eggs were observed after 72 h of incubation at 27-29o C. The mean fertilization rate was 77 ±1.45 for HCG, 72 ± 1.45 for WOVAFH treated fish and 64 ±2.08 for control. The mean hatching rate was 86.66 ± 0.88 with HCG, 86.00b ± 0.57 with WOVA FH and 82.33 ±1.20 with control. HCG gave 77 ±1.45 higher fertilization rate as well as 86.66b ± 0.88 more hatching rate of eggs respectively as compared to WOVAFH. HCG and WOVA FH were found to be more effective in induced breeding of E. suratensis.
