dc.description.abstractThis research was designed in order to examinate the effects of 17 alpha-methyltestosterone and 17 beta-estradiol hormone use on the development, growth performance, survival, sex ratio and coloration of the electric yellow cichlid (Labidochromis caeruleus Fryer, 1956). Seven different groups were designed in the study. While no hormones were added to the control diet, 6 different rates of hormones were added to the other groups. Cichlid mean weight was determined as 0.64 +/- 0.01 g, were stored such that three replications for each group. The fish were fed with the feeds for a period of 2 months. At the end of this research, the highest weight gain was determined in the 20 mg kg(-1) 17 alpha-MT group (0.39 +/- 0.17 g). When the sex change rates were evaluated, it was determined that the feminization rates in the 17 beta-ES hormone group were 80.00%, 82.22% and 86.67%, respectively, and all fishes in the 17 alpha-MT hormone group were 100% male. When the results of the physical color analysis were evaluated, it was determined that the best coloration was obtained in the 17 alpha-MT groups. At the end of the study, the 17 alpha-MT hormone was determined to have a better effect than 17 beta-ES hormone on the growth, feed conversation rate, sex change and pigmentation of electric yellow cichlid (Labidochromis caeruleus Fryer, 1956).
