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. However, stocking density had no significant effect on the survival rate. The condition factor at 500 and 750 fish/m3 was significantly lower (P<0.0005) than at 250 fish/m3. 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. Ben-Tuvia (1960) reported Tilapia galilaea whose body length was 32cm as. Three broods hatched in years of relatively high water levels (1970, 19) yielded especially low recruitment. galilaeus whose body length ranged from 13.4cm and 24.1cm in IITA lake in Ibadan. Intestinal absorption by Sarotherodon galilaeus (syn Tilapia galilaea ) of Lake Kainji. Seawater-acclimated fish of 20 g were stocked in 36 tanks at 250, 500 and 750/m3. Assuming a natural mortality (M) of 0.94, total stock size averaged 300700 tonnes in that period, while recruitment averaged < 0.73 million per year. Different sizes of fish showed different absorptive capacity. blue tilapia), Tilapia galilaea (now Sarotherodon galilaeus, Galilee cichlid), Tilapia heudeloti (now Sarotherodon melanotheron, Senegal. Abstract.The study was conducted to develop guidelines for high-density overwintering of tilapia in tanks using warm underground sea water. The experiments and model together suggest that interspecific variation in remating opportunities and clutch size may be responsible for differences in care patterns within the sub-family Tilapiini.
