Abstract

The intensive cultivation of Litopenaeus vannamei with biofloc systems is one of the most efficient way to reduce shrimp cost production, because the biofloc can be used as feed subtitution for L. vannamei cultured. This culture requires good quality and quantity of juveniles. The juveniles can be obtained from intensive system of nursery. However, this system has some limitations such as need the high stocking density and causing the increase of the feed intake.That conditions will left the unconsumed feed and shrimp metabolite excretion accumulated in the water, causing the concentration of nitrogen compounds, especially ammonia in the water increased. Currently, the bioflocs technology developed to reduce the waste shrimp even for fish farming activities. The objective of this research was to know the effect of addition of C-carbohydrate (wheat, tapioca, and mollases) on shrimp growth, survival rate, efficency of feed and feed conversion ratio of white shrimp L. vannamei. The design of the research was using a completely randomized design, consisted of four experimental treatments with four replications. The result of this research showed that the biofloc systems with addition of C-carbohydrate on growth performance of the shrimps were not significantly different (P>0.05) among those treatments. The biofloc technology with addition of C-carbohydrate using treatment B (wheat) showed higher survival rate (SR), feed conversion ratio (FCR), and feed efficiency were significantly different (P<0.05) than the C-carbohydrate from treatment C (tapioca) and D (mollases). The bioflocs system with addition of C-carbohydrate from treatment B (wheat) had SR (75.357±7.2%), FCR (1.340±0.1) and efficiency of feed (74.958±7.3%). Keyword :Wheat, tapioca, mollase
