Abstract

The intensive aquaculture industry nowadays faces two big problems such as the decrease of water quality caused by excess metabolite concentration and a lower utilization of natural feed in the high water circulation rate. Accumulation of organic material in the pond will increase population of bacteria. The process of decomposition of organic materials by aerobic bacteria will cause the decrease in the oxygen content in water. Therefore, the conversion of toxic ammonia to nitrat is highly useful which can be succeeded through the implementation of biofloc technology and maximize the contribution of natural feed in intensifying aquaculture technology.This study aims to gain information on nutrient composition of biofloc caused by the use of different commercial probiotic through the formation of biofloc including probiotic A, probiotic B and without probiotic. Parameter monitored in this research including biofloc nutrition (protein and fat) and other supporting parameters including plakton diversity index, plankton domination index, C/N ratio, N/P ratio, pH, termperature and dissolved oxygen. Data analysis was carried out by ANOVA (analysis of variance) and descriptive.This resaerch demonstrated that different probiotic significantly affected on the protein and fat content of biofloc. Probiotic containing different bacterium with wide variety can enrich biofloc nutrient.
