The objectives of this research were carried out to determine exposure time of giant gouramy larvae in triiodothyronine (T3) hormone solution on development, growth and survival rate. One-day old larvae were immersed in 0,1 ppm T3 hormone solution for 0, 2, 4, 6, 8, 16, and 24 hours. Results showed that treated larvae developed faster than control larvae. At first, second, fifth, sixth and seventh week, larvae that immersed in T3 hormon solution had total length longer than that of control. Treated larvae had average body weight heavier than that of control until seven weeks of experiment. Immersion of larvae for 16 hours gave the best result in term of length and average body weight. The best survival rate of larvae were obtained from 8 hours treatment.
