      Abstract
      Experiment was performed to assess the effect of 17-methyltestosterone (MT) treatment on Congo tetra fish larvae. To evaluate the optimal pattern of MT treatment, three different treatments were administrated. Three months old larvae were submerged in three different doses of MT; 1, 2 and 4 mg/l. These studies showed that the highest percentage of male fish was obtained by 4 mg/l MT treatment, 87,17%. The 2 mg/l and 1 mg/l MT treatments obtained 77,53% and 69,86% male respectively, two times higher than control, 38,96%. On the other hand, the 4 mg/l MT treatment also resulted the highest percentage of hermaphrodite fishes, 17,58%. The highest survival rate was shown by 1 mg/l MT treatment, 62,77% and the lowest was shown by the 4 mg/l MT treatment, 47,20%. The highest rate of fish length and weight was shown by the 4 mg/l MT treatment, 4,4 cm and 1,65 gram respectively. These findings suggest that MT treatment offers an advantage in growth of tetra Congo larvae.
