Abstract/Description: | An experiment was conducted for 120 days to evaluate optimum dietary lipid require-ments for gonadal maturation of Cyprinus carpio fed with varying dietary lipid levels under biofloc-based systems (BFT). About 180 fingerlings (22 g ± 0.05) were randomly distributed in 15 tanks (300 L) at the rate of 48 no./m2 and fed with varying lipid lev-els (T1—4% lipid with BFT, T2—6% lipid with BFT, T3—8% lipid with BFT, T4—10% lipid with BFT, control—10% lipid without BFT). The C/N ratio of 20:1 was maintained using tapioca flour as carbon source. Biofloc units supplemented with 8% dietary lipid (T3) showed advanced maturation in terms of absolute fecundity (9,913 ± 7.62), relative fecundity (229.0/g ± 11.92), gonadosomatic index (24.47% ± 1.27), hepato-somatic index (1.97% ± 0.07), condition factor (0.02 g/cm3 ± 0.00) compared with control (clear water with 10% lipid) (p < .05). Histological observations of gonads also revealed that the biofloc groups with supplementation of 8% dietary lipid promoted gonadal maturation for female oocyte and 6% dietary lipid promoted maturation for males, compared with control (clear water with 10% lipid). The results obtained in this experiment elucidate that the biofloc improves gonadal maturation of common carp broodstock at a dietary supplementation with 8% lipid compared with conventional system of broodstock management. |
