Growth and Survival of Bighead Carp (Hypopthalmichtys nobilis) Fingerlings at Varying Stocking Densities in Freshwater Pond

A 60-day experiment to determine the growth and Survival of bighead carp Hypophthalmichthys nobilis) fingerlings at varying stocking densities in freshwater pond was conducted at the College of Fisheries Laboratory and Research Station, Mindanao State University, Barangay Bawing, General Santos City from Dec 28, 2018 to February 26, 2019. Nine units of B-net cages with 1x1x1.5m dimension were installed in an experimental pond is enclosures. Three treatments with varying Stocking densities were tested. The treatments were is follows: Treatment I(20 Bighead carps); Treatment II (30 Bighead carps) and Treatment III (40 3ighead carps). Each treatment was replicated thrice. After 60 days of culture, bighead carp in Treatment I obtained the highest mean final Weight, weight gain and daily weight gain of 8.702,6.7g and 0.11g, respectively, followed by Treatment II with 6.60g, 4.6g and 0.08g and Treatment II with 5.602, 3.32 and 0.062. The Analysis of Variance (ANOVA) showed that there was Significant difference among treatment means (P<0.05). The mean survival rate of the bighead carp in all treatments was 100%. The FCR of bighead carp in Treatment I with 4.7, was better compared to that of Treatment II and Treatment III both with (5.7). Analysis of variance revealed significant difference among the treatment means (P<0.05). On the condition Of the experiment, it is concluded that Stocking density of 20fish/ m^3 obtained the best results on growth performance and survival.
