The Habas were stocked with 9 females and 3 males each (sex ratio 3 : 1 ) to test the best treatments from phase one as following in Table 2: Table 2: Explanation of the experimental reproductive trait during the 2nd phase: fed on Basal ration (BR) fed on BR, fed on BR fed on BR + 700 mg L - carnitine / Kg diet, fed on BR + 0.5 g Therigon/ kg diet fed on BR, fed on BR + 0.5 g Therigon/ kg diet fed on BR + 700 mg L - carnitine / Kg diet, fed on BR +2 g Nuvisol Hatch P / Kg diet fed on BR, fed on BR +2 g Nuvisol Hatch P / Kg diet fed on BR + 700 mg L - carnitine / Kg diet. Table 4: Females' sexual parameters of brood stock Nile tilapia as affected by the dietary supplementations for 19 days feeding trial in Habas in an earthen pond (means* SE). Therefore, it was strongly suggested that relationship between carnitine secretions, seminal quality and OXPHOS activities could be because of a parallel response to the same regulatory event [47, 48]. The average efficacy of sex-reversal ranges from 95 to 100 per cent depending on the intensity of management. The significantly heavier body weight (288.9 23.8 g) after the 19 day-study was realized by the fish in the 8th Haba (20 mg gibberllic acid / Kg diet) followed by Haba No. On the 22nd July, the fry were collected and counted. Gibberellins (GAs) are involved in a wide range of plant developmental processes. Gibberellins are tetracyclic diterpenes that are found in plants and fungi.
