The findings indicate that the optimum stocking density for overwintering tilapia in tanks using warm underground sea water is 750 fish/m3 with a water flow rate of 0.1 l/kg fish/min and a feeding rate of 0.75%/day. Significantly higher mean individual weight gain, specific growth rate, and survival rate were observed at 1.0%/day than at the 0.75%/day feeding rate. Significantly better specific growth rate, condition factor and feed conversion were observed at a water flow rate of 0.2 l/kg fish/min than at 01 l/kg fish/min. This is a relatively large cichlid at up to 41 centimetres (16 in) in total length and about 1.6 kilograms (3.5 lb) in weight. We evaluated the diet of Nile tilapia kept in ponds for four. It is very important to local fisheries and the species is also aquacultured. However, stocking density had no significant effect on the survival rate. niloticus at the post-larval stage, and if the way they capture food may determine prey size. The condition factor at 500 and 750 fish/m3 was significantly lower (P<0.0005) than at 250 fish/m3. Recruitment to the fishery, at 1720cm, occurred between ages l+and3+.The highest growth rates for age-1 T, galilaea, 12 mean weight per day, occurred in April and May, the Peridinium season. Fish were fed at the rates of 0.75% and 1.0% of biomass per day.After 135 culture days, the mean individual weight gain and specific growth rate decreased, whereas feed conversion increased significantly (P <0.0001) with the increase in stocking density. Water flow was regulated at 0.1 and 0.2 l/kg fish/min. Seawater-acclimated fish of 20 g were stocked in 36 tanks at 250, 500 and 750/m3. Abstract.The study was conducted to develop guidelines for high-density overwintering of tilapia in tanks using warm underground sea water. Bayesian length-weight: a0.01778 (0.01394 - 0.02268), b3.00 (2.93 - 3.07), in cm total length, based on LWR estimates for this species (Ref.
