Determination of Effective Microbial Community for Biofloc Shrimp Culture System


Author(s): K Sakkaravarthi

Abstract: This experiment was conducted for 50 days in four 100 L tanks with 15 cm of bottom area filled with soil. and completely randomized with three replicates for each one of four treatments. Penaeus monodon seeds were stocked at 30/m². All tanks were filled with chlorinated sea water and each tank received following microbes, Tank A – with only diatom, Tank B – with only Nitrogen cycle bacteria, Tank C -- with only Sulphur cycle bacteria, Tank D -- with Diatom, bacteria involved in both nitrogen and sulphur cycles. The results, with a particular group of microbes were not effective, but when diatom, nitrogen and sulphur cycle bacteria work together in a culture environment, these can control water quality very effectively and gives best result. The tank D showed highest 7.5 gm ABW, 90% survival, 18 ml biofloc formation and lowest FCR 1:1.5. The results were statistically significant (p<0.05).
