Sex Reversal of the Giant Freshwater Prawn Macrobrachium dacqueti through Androgenic Gland Ablation

The male Macrobrachium species (giant freshwater prawn) typically achieve better growth and a larger harvest size than females. Hence, it is clear that the monosex culture of all-male prawn populations would be inexpensively advantageous. This study aimed to determine whether androgenic gland (AG) ablation induces sex reversal giant dacqueti. AG was ablated through bilateral microsurgery (AG ablation) let them recover for two months. weight length were also measured every 15 days. Results revealed removal from males immature M. dacqueti resulted in reversal, with 70% female differentiation. Successful neo-female prawns exhibited development an ovary orange coloration as matures. Andrectomized did not develop appendix masculina second pleopod, indicator suspected prawn. A significant increase observed within months compared control. Based on result study, possible ablation. Therefore, sex-reversed (neo-females) can used breed normal produce progenies since both parents possess hormones, thereby rendering huge advantage culture.
