BUDIDAYA UDANG VANAME (LITOPENAEUS VANNAMEI) SUPER INTENSIF DENGAN PADAT TEBAR BERBEDA MENGGUNAKAN SISTEM ZERO WATER DISCHARGE

Abstract

This study aims to determine the growth rate, survival and feed conversion ratio in super intensive vaname shrimp culture with different stocking densities using the Zero Water Discharge system. This research was conducted in August-October 2018, at Hatchery Windu Lestari Kel. Wolulu Kec. Watubangga Kab. Kolaka. The test animal used was PL 10 vaname shrimp fry obtained from commercial hatcheries. This study used a completely randomized design (CRD) method with three treatments and three replications. Treatment A: stocking density 40 heads / 0.1m3 , treatment B: stocking density 50 heads / 0.1m3 , treatment C: stocking density 60 heads / 0.1m3 . The parameters measured were survival, absolute weight growth, specific growth rate, feed conversion ratio and water quality. The results of statistical analysis using the ANOVA test showed that the stocking density was significantly different on the growth of absolute weight, specific growth rate and feed conversion ratio, but not significant on the survival and physicochemical parameters of water in super intensive vaname shrimp culture using the ZWD system.Thehighest absolute weight growth was in treatment A (7.54 ± 0.15 g/ind), treatment B (6.47 ± 0.10 g/ind) and treatment C (6.07 ± 0.10 g/ind).The highest specific growth rate was in treatment A (7.90 ± 0.03%/day), treatment B (7.68 ± 0.02%/day) and treatment C (7.59 ± 0.02%/day).The smallest feed conversion ratio was in treatment A (1.54 ± 0.03), treatment B (1.56 ± 0.02) and treatment B (1.62 ± 0.02).
