Pengaruh perendaman dosis hormon methyl testosteron berbeda terhadap sintasan hidup dan pertumbuhan larva ikan nila, Oreochromis niloticus
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.
