Abstract

This study aimed to determine the effect of methyl testosterone hormone for immersion of tilapia larvae for 8 hours on survival rate and growth of tilapia larvae (Oreochromis niloticus). Test animals used were as many as 240 larvae of tilapia, with methyl testosterone hormone treatment as much as A = 0 mg / l, B = 1,5 mg / l, C = 2,5 mg / l, and D = 3,5 mg /. Survival rate of tilapia larvae live on the highest dose of 1.5 mg / l which is 93.33% (A) followed by 83.3% (C), 80% (A), 75% (D). Highest absolute growth of larvae at the 2,34 cm (D) followed at 2,23 cm (C), 2,21 cm (B), 2,13 cm (A). The results showed that the differences in the dose of methyl testosterone did not give significantly different effect on survival rate of larvae and absolute growth. Keywords: immersion, methyl testosterone hormone, Oreochromis niloticus, survival
