EFFECT OF ADDING PROBIOTIC DOSAGE OF EFFECTIVE MICROORGANISM 4 (EM4) TO COMMERCIAL FOOD ON GROWTH OF MUTUAL WEIGHT OF VANAME WATER (Litopanaeus vannamei) DOC 40 IN EXPERIMENTAL TANKS

Abstract

Superintensive technology vaname shrimp (Litopenaeus vannamei) farming is characterized by very high stocking densities, which can trigger appetite and water quality to decline drastically. One of the mitigation efforts against these events is to add a dose of probiotic effective microorganism 4 (EM4) to commercial feed. The purpose of this study was to determine the effect of adding a dose of probiotic effective microorganism 4 (EM4) in commercial feed on the absolute weight growth of vaname shrimp DOC 40 experimental tanks. This study used an experimental method with a completely randomized design (CRD) consisting of 5 treatments with 5 replicates. This study uses the treatment of adding doses of EM4 probiotics to commercial feed, treatment A; 75 ml/kg feed, B; 150 ml/kg feed, C; 225 ml/kg feed, D; 300 ml/kg feed, and E; 375 ml/kg feed. The test animals used 40 DOC vaname shrimp with an average weight of 5 g/head. The stocking density was 1 tail/liter and the experimental media used seawater with a volume of 3 liters/tank. The results showed that treatment C gave the highest results on absolute weight growth of 40 DOC vaname shrimp at 4.5 g/head. Water quality data obtained water temperature ranged from 278 – 29,1 0C, acidity ranged from 7,55 – 7,8 and dissolved oxygen ranged from 5,6 – 6,1 ppm.
