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

Abstract

Penelitian ini bertujuan untuk mengetahui laju pertumbuhan,kelangsungan hidup dan rasio konversi pakan pada budidaya udang vaname super intensif dengan padat tebar berbeda menggunakan sistem Zero Water Discharge (ZWD). Penelitian ini dilaksanakan pada bulan Agustus-Oktober 2018, di Hatchery Windu Lestari Kel. Wolulu Kec. Watubangga Kab. Kolaka. Hewan uji yang digunakan adalah Benur udang vaname PL 10 yang diperoleh dari hatchery komersil. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan tiga perlakuan dan tiga ulangan. Perlakuan A : padat tebar 40 ekor/0.1m 3 , perlakuan B : padat tebar 50 ekor/0.1m 3 , perlakuan C : padat tebar 60 ekor/0.1m 3 . Parameter yang diukur adalah kelangsungan hidup, pertumbuhan berat mutlak, laju pertumbuhan spesifik, rasio konversi pakan dan kualitas air. Hasil analisis statistik dengan uji ANOVA menunjukkan bahwa padat tebar berbeda 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 / 0.1m 3 , treatment B: stocking density 50 heads / 0.1m 3 , treatment C: stocking density 60 heads / 0.1m 3 . 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 physico-chemical 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).
