| Özet |
| This research was designed in order to examinate the effects of 17α-methyltestosterone and 17β-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 17α-MT group (0.39±0.17 g). When the sex change rates were evaluated, it was determined that the feminization rates in the 17β-ES hormone group were 80.00%, 82.22% and 86.67%, respectively, and all fishes in the 17α-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 17α-MT groups. At the end of the study, the 17α-MT hormone was determined to have a better effect than 17β-ES hormone on the growth, feed conversation rate, sex change and pigmentation of electric yellow cichlid ( Labidochromis caeruleus Fryer, 1956). |
