Effect of different sources of carotenoids on growth performance, stress response, and flesh quality in fingerlings grey mullet, Liza ramada in cultured floating cages [electronic resource].

The present study was conducted to evaluate the sutability of carotenoid sources (tomato powder, 20, 40 and 60 g 1 kg; pepper powder, 30, 60 and 120 g I ~~ ~d Synthetic Astaxanthin (vit A) at 70, 75 and 80 mg I kg, respectively on growth p~rformance, stress response, feed utilizatiOn, body composition, and final tlesh quality of Liza ramada. A total number of 20 Lzza ramada ( 4 g) were randomly distri?uted into 20 ~apas, and were fed daily at a rate of 5 % of fish live body weight through 90 days, each t~eatme~t ~oup was applied at two replicates. The results showed that the effect of Synthetic Astaxanthin (vitA) (80 mg) w~ hi~hl~ sigmficant among all the other treatment in FBW, ADO. BWG, SGR, and PER. Pepper powder at 30g showed a h~gh .sigmficant crude protein % (58.15±0.15) among all the other treatments. The TBARS values in Liza ramada tlesh showed a significant decrease among all carotenoid sources as the time of frozen storage elapsed as compared to control. The e~fect of Paper powder at 120 g was highly significant from the other treatment in carotenoid flesh content while the control d1dn:t record any deposit of carotenoids. The study demonstrated that the carotenoids sources showed significant effect on survival, growth performance, feed utilization and TBARS values.
