Abstract
- This study was designed to determine the ideal dosages of marigold (Tagetes erecta) and synthetic carotenoid in blue streak hap (Labidochromis caeruleus) and pindani (Pseudotropheus socolofi) fry (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 (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 (2, 4, 8%) which obtained from the first experiment were compared with the different synthetic carotenoid dosages (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 (P
