The seven experimental diets (45.64% CP) were formulated to contain synthetic astaxanthin (SA; 0.1 g kg−1), marigold flower meal (MFM; 0.2 g kg−1) or crab waste meal (CM; 10 g kg−1), with or without sodium taurocholate (ST; 0.4 g kg−1); the control diet contained no supplementation. The experiment was conducted for 8 weeks. The results show that seabass fry fed the diets containing different sources of carotenoids, especially with ST, demonstrated higher growth efficiency, survival (%), feed efficiency, protein and ether extract contents of fish body. The best results were found with DietMFM+ST. Whole-body carotenoid levels increased significantly with all supplementation treatments; the highest level was observed with SA, followed by fish fed DietMFM and DietCM, especially with ST co-supplementation. Moreover, thiobarbituric acid-reactive substances were significantly reduced in fish fed the diets containing different sources of carotenoids compared to the control diet. The total antioxidant status significantly increased in fish fed DietSA and DietCM alone or with ST compared to the control group. In conclusion, these results reveal that DietMFM+ST is the most suitable treatment for improving growth, feed efficiency, and the protein and ether extract contents of seabass fry compared to other sources of carotenoids. The best oxidant/antioxidant balance and carotenoid content were achieved using SA, CM and MFM with ST supplementation. Citing Literature Volume48, Issue7July 2017Pages 3848-3858 RelatedInformation
