ABSTRACT
Nile Tilapia (Oreochromis niloticus) is the most common marketable fish species in biofloc throughout the world. It has higher growth rate and is reared in limited resources when compared to other aquaculture species. This research work identified the requirements needed for installation of biofloc setup in winter session; different physico-chemical parameters and optimized the floc density for growth of Nile Tilapia (O. niloticus) in the study area. A total of three tanks were taken and the floc concentration was 121.071g in tank first, 131.16g in second and 135.19g in tank third. Total fingerlings (750) stocked were divided in three tanks (dimensions of length was 15feet, height=4.5feet, water level=3.2 feet) with water volume of 17000 liters in each tank. Formulated feed was used with 30% and 40% crude protein (CP) and buffalo meat. Water temperature was maintained at 31oC using heater (500Watts) with thermostat. The results were recorded with significant value in the growth of fish during 4th to 9th weeks. The values of fish weight were recorded higher (P<0.05) in group 3 than the group 1 and group 2. The floc concentration, feed and physico-chemical parameters have positive effects on biofloc system at winter session for quality production of Nile Tilapia (O. niloticus) production.
