الملخص

This study conducted in the farm and the fish hatchery at Sudan University of Science and Technology, in order to study some biological factors affect the successful of cultivation Nile tilapia (Oreochromisniloticus) fingerlings in tanks culture. Plastic tanks used for easy observation and periodic measurements.A trial was conduct to study the growth performance of O. niloticus fingerlings under three stocking densities; 10 fish tank‾¹ (SD1), 15 fish tank‾¹ (SD2) and 20 fish tank‾¹ (SD3). The results of the trial with respect to growth performance showed a significant preference (P 0.05). A trial was conduct to study the effect of different feed frequencies (FF) on the growth rates of O. niloticus fingerlings. The results indicated that, there is no significant difference (P> 0.05) due to repeated feeding frequency twice/day (FF1), three times/day (FF2), and four times/day (FF3), with no effect on survival rate by changes daily feeding frequencies. A trial was conduct to study the growth efficiency of O. niloticus fingerlings under influence of three feeding ratio; 5% (FR1), 9% (FR2), and 13% (FR3) from body weight. The results of the trial showed that, there is no significant benefit for daily weight gain due to different daily feeding ratios, with a significantly higher (P 0.05) in DO, temperature, pH, P, No2, No3 and ammonia concentrationsdue to cultivation O. niloticus fingerlings in tanks within different stocking densities trial, different feed frequencies trial and different daily feed rates trial. The study of the proximate chemical analysis of O. niloticus fingerlings body showed a significance difference (P 0.05) within different stocking densities, different feed frequencies and different feed rates trials.
