Effect of vitomolt plus dose in feed on growth and survival of juvenile vaname shrimp (Litopenaus vannamei)

Abstract

Slow growth and mortality due to disease are major problems in shrimp farming. This study aims to determine the best vitomolt dose in feed for the growth and survival of juvenile vannamei shrimp (Litopenaus vannamei). This research was conducted from July to September 2020 at the Mini Hatchery of the Faculty of Marine and Fisheries Sciences, Hasanuddin University, Makassar. The test animal used in this study was juvenile shrimp vaname (Litopenaeus vannamei) with an average initial weight of 1.5 g obtained from the shrimp hatcheries in Kab. Pangkep. The number of shrimp used in this study was 240 heads with details of 20 per container, with the treatment given was the addition of a different dose of vitomolt plus in artificial feed. The study was designed using a completely randomized design (CRD) consisting of 4 treatments with 3 replications each, namely A: control, B: 1.5 vitomolts plus g / kg of feed, C: 3.0 vitomolts plus g / kg of feed. and D: 4.5 vitolts plus g / kg of feed. The results showed that the vitomolt plus dose had a significant effect on the growth and survival of vannamei shrimp. The highest growth of shrimp was obtained in the treatment of 4.5 g / kg of feed, which was 5.85 g compared to only 3.5 g of control (P <0.05). The highest survival rate was obtained in the 3.0 g / kg feed treatment which was 80%, while the control was only 48.33% (P <0.05). The results showed that vitomolt plus with the right dose gave better growth and survival. The best vitomolt dose is 3.0 g / kg of feed - 4.5 g / kg of feed
