Abstract :This study was designed to determine the ideal dosages of marigold insert ignore into journalissuearticles values(Tagetes erecta); and synthetic carotenoid in blue streak hap insert ignore into journalissuearticles values(Labidochromis caeruleus); and pindani insert ignore into journalissuearticles values(Pseudotropheus socolofi); fry insert ignore into journalissuearticles values(Cichlidae);, and to compare effects on the growth and skin coloration. In the first experiment, the blue streak hap and pindani fry fed with different levels of water-soluble marigold flower meal insert ignore into journalissuearticles values(0, 2, 4, 6, 8, 10 and 12%); were tested for 30 days to find the optimum skin coloration and growth parameters. Then, in the experiment, the most effective doses of water-soluble marigold flower meal insert ignore into journalissuearticles values(2, 4, 8%); which obtained from the first experiment were compared with the different synthetic carotenoid dosages insert ignore into journalissuearticles values(50, 100 and 150 mg kg-1); for 30 days. At the end of the first experiment, weight gain and the skin coloration degrees for both fish species were increased significantly by supplementation of 4% water-soluble marigold flower meal supplemented diet insert ignore into journalissuearticles values(P<0.05);. In the second experiment, 50 and 100 mg kg-1 of synthetic carotenoid and 4% water-soluble marigold flower meal supplementation showed better performances concerning growth and skin coloration insert ignore into journalissuearticles values(P<0.05);. This study showed that the 4% water-soluble marigold flower meal could be used as an alternative and useful pigmentation source for blue streak hap and pindani.
