Abstract: The purpose of this experiment is to provide information that effects thyroxine hormone development ovary of female mud crab in traditional ponds. A study was conducted in traditional ponds in small islands like Sadau, Tibi, Tias, Mangkudulis and Tarakan islands on the north Kalimantan to evaluate the viability of ecology and biology drive in mature for reproduction females of the mud crab (Scylla serrata.). The hormone thyroxine supplementation started of mud crabs with vitellogenic stage 2 (maturing). This experiment consists of 3 triplicate treatments and all treatment of supplementation hormone thyroxine are doses; 0ug/BW(control); 0.1ug/BW and 0.2ug/BW. Each treatment was repeated six (6) times. The population structure and maturity stages females of the mud crab (Scylla serrata) from traditional ponds are among crustaceans of commercial value. In north Kalimantan, the maturity stages females of the mud crab crabs are landed by artisanal fishermen. Rising population in the coastal areas and high demand for the crabs has led to increased pressure on the crabs. The result of the research is the accumulation of mud crab female mature as 237 with various size; Weight and different levels of gonad maturity. Based on the weight of mature crabs gonad crab caught in ponds can be grouped up; Small size (180-300 g) of about 15% and medium size (301-400 g) of about 62% and large size (401-550g) of about 23%. The stage maturity in traditional ponds of female mud crab have as 45.37% still in the mature ovary stage II and it has as 58.27% in the mature ovary stage III. The supplementation low dose 0.2 µg/BW needed 12 days to mature ovary from vitellogenic stage 2 to vitelogenic stage 3 than the control needed 23 days, while the supplementation dose 0.1 µg/BW needed 13 days. The supplementation thyroxine hormone dose 0.1 µg/BW and 0.2 µg/BW faster to maturity ovary from vitellogenic stage 3 to berried than control. Based on the analysis of variance of the supplementation thyroxine hormone in the female S. Serrata indicates that there is a real effect on the acceleration of mature ovarian. The treatments supplementation thyroxine hormone low dose resulted from a significantly (P<0.05) time maturity ovarium than control.
