This experiment was conducted to investigate the effect of triiodothyronine and cortisol on the development, growth, and survival rate of sand goby larvae. The experiment was carried out at Kolan Percobaan Babakan, Faculty of Fisheries and Marine Sciences, IPB Bogor. The larvae were immersed in solution of A (T3 2 mg/1 + C 1 mg/1), B (T3 2 mg/1 + C 0, 1 mgll), C (T3 2 mg/1 + C 0,0 1 mg/1) dan D (without hormone) for one hour. After treatment, larvae were reared in aquarium (50x50x50 cm). Larvae were fed by rotifer and phytoplankton, three times a day. Larval development, growth and survival rate were observed. Result showed that T3 2 mg/1 +C 1 nig/1 and T3 2 mg/1 + C 0, 1 mg/1 could accelerated development of swim bladder and eyespot of larvae. Treatment did not effect body pigmentation and growth; but effect survival rate of sand goby larvae.
