Abstract

The present study was conducted to evaluate the sutability of carotenoid sources (tomato powder, 20, 40 and 60 g / kg; pepper powder, 30, 60 and 120 g / kg and Synthetic Astaxanthin (vit A) at 70, 75 and 80 mg / kg, respectively on growth performance, stress response, feed utilization, body composition, and final flesh quality of Liza ramada. A total number of 20 Liza ramada (4 g) were randomly distributed into 20 hapas, and were fed daily at a rate of 5 % of fish live body weight through 90 days, each treatment group was applied at two replicates. The results showed that the effect of Synthetic Astaxanthin (vit A) (80 mg) was highly significant among all the other treatment in FBW, ADG, BWG, SGR, and PER. Pepper powder at 30g showed a high significant crude protein % (58.15±0.15) among all the other treatments. The TBARS values in Liza ramada flesh showed a significant decrease among all carotenoid sources as the time of frozen storage elapsed as compared to control. The effect of Paper powder at 120 g was highly significant from the other treatment in carotenoid flesh content while the control didn'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.
