Abstract

The present study was carried out on monosex Nile tilapia Oreochromis niloticus for one year.In Fish Research Station belonging to National Institute of Oceanography and Fisheries. The aim Of work was to gain basic information about the Effect of supplementation of 400-mg/kg diet ± Ascorbic acid (AA) and / or 2000 mg/kg diet a-tocopherol acetate (α- TOH). The data showed that the highest average growth Performance and protein utilization parameters were occurred when fish fed diet supplemented With (AA) and (a TOH) together. Also,Supplementation with (AA) and (a-TOH) had No adverse effect on the fish. The data cleared that the highest concentrations of (AA) and (α-TOH) were found in whole body, blood, liver and anterior kidney of fish fed diet supplemented with (AA) and (a-TOH) together. The highest values of haemoglobin, %; haematocrit, %; erythrocite count (10⁶/mm³) and lowest values of leucocyte count ( (10³/mm³) were Occurred when fish fed diet supplemented with (AA) and (α- TOH) together. Also, the high- Est total serum protein (TSP) and their fractions(TSA) and (TSG) values were found when fish Fed diet supplemented with (AA) and (α- TOH) together. The present study suggested that the raise of vitaMin C and vitamin E requirements to 400 mg/kg Diet and 2000 mg/kg diet respectively, are Adequate for high and rapid growth as well as no Adverse effect on monosex Nile tilapia O. niloticus
