The Effect Of Addition Vitamin C On Feed With Different Doses Towards Growth And Survival Rate Of Giant Prawns (Macrobrachium rosenbergii) In the Recirculation System

Abstract

ABSTRACT

This research was conducted on March 18^th-May 1^st, 2019 in the Laboratory of Aquaculture Technology, Faculty of Fisheries and Marine, University of Riau. The aimof this study is to determine the effect of the best dose of vitamin C addition of feed on the growth of giant prawns. The container of this research used a 60x40x40 cm ³ aquarium with 20 aquariums with a stocking density of 15 prawns/aquarium. This study used a Completely Randomized Design (CRD) with one factor of five treatment levels and four replications. Each treatment was given the addition of vitamin C as much as P₀ (0 m g/kg), P₁ (300 mg/kg), P₂ (450 mg/kg), P₃ (600 mg/kg), and P₄ (750 mg/kg) feed. The results of the research showed that the best treatment was found in P₃ (600 mg/kg) feed resulting in absolute weight growth of 1,26 g, specific growth rate of 7,72% and survival rate of 98,33%.
