Abstract:	Bivalve Lea is one of economically freshwater mussels. It has high economical value as a sources of animal protein. All these years, it relays on natural catching. For a sustainable resource management, a controlled aquaculture technique should be used to produce the seed. The success of aquaculture requires the availability of information about reproduction and gonad development, especially ovary and gonad somatic index (GSI). The aims of this research is to analyse ovary development of female Taiwan mussel Sample of this research was taken randomly, consisted of 30 individuals for gonad maturity level observations, meanwhile 107 individuals were used to measurethe gonado's somatic index. The results of this research suggested that gonad maturity levels of Taiwan mussel consisted of 5 levels, namely primodium, developing, maturing, ripe and spent. Average values of gonado somatic index for immature Taiwan mussel and mature Taiwan mussel were 3.46 +- 1.46% and 6.00 +- 2.29 %, respectively.
