Effect of supplemented diet with maturation plant extract on reproductive performance of Etroplus suratansis

This study was carried out to understand the effect of herbal maturation diet on reproductive successes in Etroplus suratensis. Three herbal maturation diets (EXD1, EXD2, EXD3) and one control diet (EXD0) were prepared with different combinations of herbal ingredients and normal diet ingredients. The experimental animal were observed for the success in reproductive performance like Gonado Somatic Index (GSI), fecundity, striping response, percentage of fertilization, percentage of hatching, percentage of deformed and formed larvae, volume of milt, number of sperm cell, percentage of sperm motility, sperm survival time, percentage of active sperm. The EXD3 diet combination increased the GSI (3.14), fecundity (1325), striping responds (87.23), percentage of fertilization (96.45) percentage of hatching (91.89), percentage of formed larvae (87.53), volume of milt (287 μl), number of sperm cell per μl (1912) percentage of sperm motility (94.18), time of sperm survival (72′15″) and percentage of active sperm cells (92.27) and reduced deformed larva percentage (4.36). From this observation it is more evident that the combination of EXD3 was the best combination and it could be utilized for the formulation of maturation diets for E. suratensis.
