The reproductive performance of captive tiger shrimp (Penaeus monodon) is a crucial aspect of sustainable aquaculture. This study explores the potential of Cyperus spp. extract components (CE) to enhance the reproductive performance of captive tiger shrimp Penaeus monodon. Our methods involved feeding captive tiger shrimp Penaeus monodon with feed enriched with 0, 300, 400, and 500 µg CE/g Body Weight (BW) over a 60-day rearing period. Eyestalk ablation was used as a positive control. Post-feeding experiments, we observed the shrimp for their reproductive performance. The results were promising: the male broodstock exhibited the highest molting percentage when fed with feed enriched with 400 µg CE/g BW, while females showed the highest molting percentage at 500 µg CE/g BW. The highest percentage of males carrying spermatophores and mating females was observed at 500 µg CE/g BW. Broodstockfed feed enriched with 500 µg CE/g BW produced 337,339 eggs with an average egg diameter of 289.5 µm, yielding 16,175 nauplii. The highest expression of vitellogenin and spermatogenesis was found in the 400-500 µg/g BW range. These findings suggest that the optimal dose of CE for promoting gonadal maturation in captive shrimp broodstock is 400-500 µg/g BW. The potential of this study to increase larval production in aquaculture practices is significant. By utilizing environmentally friendly plant-derived hormones like CE, we can develop more sustainable aquaculture methods, thereby reducing the environmental impact associated with traditional hormone induction strategies.
