Abstract

Abstract. Second generation of Fenneropenaeus indicus have been produced in pond at Main Centre for Brackishwater Aquaculture (MCBA) Jepara, Indonesia and subjected to use for evaluation on their reproductive performance without ablation. Pre-maturation with and without biofloc technology (BFT) system were assessed during the trials. First trial (non-BFT), amount of 10 months old broodstock (37.35 +/- 4.90g females and 25.15 +/-2.66g males) were acclimatized, while the second trial a total of 190 pcs of females (38.05+/-4,19g) and 195 pcs of males (27.85+/-2.16g) at 11 months olds were culture separately during four weeks and reared into biofloc system prior maturation performed. Molasse was used as carbon sources in order to maintain C/N ratio around 15. Maturation processed conducted using rectangular cement tanks (30 m3 active volume) into indoor system at 10h light and 14h dark condition. Animal test mainly fed on squid (morning) and oyster (daytime), while live Nereis sp. being feed at noon at a ratio 1:1:1 of 30% biomass/day. Daily water exchange rate of 100% in the morning and afternoon, respectively. It was found that the latency period of BFT (6d) and non-BFT (7-8d) treated broodstock within the range of common intervals for F. indicus. However, the percentage of weekly spawners (%), nauplii production (pcs/spawner), and postlarvae survival shows any significant differences (P<0,05) were 80% vs 55%, 33.850 vs 51.246, and 30.7% vs 23.26%, respectively. Results finding shown that domesticated F. indicus can successfully produced healthy post larvae without prior broodstocks ablation. Study on BFT during pre-maturation of these species firstly report and there is the need for further research in terms of duration, nutritional status of the broodstock, and post larvae growth performances in pond.
