Abstract | Tor tambroides fry with a mean of 8.0±0.72mm standard length (SL) and weighing (W) 0.06±0.01g were stocked at the rate of fifty (50) individuals in each of the fifteen 150-1 rectangular fiberglass tanks for a period of 5 weeks. 45% protein diet without additive Spjrulina was treated as control and denoted as S0 While diets refer to S1, S2, and S3 had respective Spjrulina percentages of 0.05, 0.10, and 0.20 Respectively. The experimental fish were collected both at the beginning and the end of the experiment to determine the growth and carotenoid pigments deposited in Tor tambroides fry .Fish fry fed on diet with 0.10% Spjrulina showed significantly higher growth (P<0.05) and carotenoid deposition in flesh and skin than those of other diets. This study indicates that bèta-carotene was a dominant carotene in fish flesh compared to other carotenoids. Furthermore, it can be concluded that the utilization of bèta-carotene depends on the optimum level beyond of which would give the lower efficiency. |
