Abstract
The amount of post spawning of F. merguiensis broodstocks were subjected to further culture for three months period and fed various diets under recirculation system. The aim of the study was to evaluate their reproductive performances and seed production parameters. The broodstocks were fed a fresh diet consisting of chopped squid and Nereis sp, combined with a maturation diet (Skretting-Crude Protein: 59%). After the three-month culture period, a total of 17 pairs of broodstocks (53.53 ± 7.0 g for females and 28 ± 2.39 g for males) were selected, ablated, and reared for another ten days. Reproductive performance of these broodstocks and the post-larvae produced were observed. Broodstock’s performance in terms of egg and nauplii production was comparable to that naturally matured (wild) brooders. The average nauplii production was 250,000 individuals, with a latency period starting on the third day after ablation, and 77% of the broodstocks spawned within the given period. Furthermore, larval survival was high and reaching up to 40% until Pl-10. In conclusion, banana shrimp broodstocks can be maintained for certain period while maintaining their reproductive performance, if the diets and environmental parameters are kept within favorable conditions.
