本試驗進行鋸緣青蟹成熟度分析，公蟹甲殼長13.4±1.6 cm重量平均430.6±172.4 g，生殖腺平均占總重4.4±1.9 %；母蟹甲殼長13.4±1.7 cm重量平均 367.9±124.4g，性腺指數 (Gonadosomatic Index; GSI) 11.9±6.5%，且隨著蟹體量 增加，其生殖腺也隨著增加，母蟹性腺指數 (GSI) 比較公蟹高。而公蟹生殖腺與體 重相關性迴歸系數 (R 2 ) 0.6861, 較母蟹迴歸系數 (R 2 ) 0.4207高。30天培育種 蟹期間，母蟹抱卵率75%，抱卵母蟹孵化率67%。母蟹肥滿度越高，其抱卵的比例則 越高。

 The mud crab Scylla serrata is considered a potentially important marine crab species for selective breeding. Here, the first examined we analyzed the correlation between the gonad and their effects on body weight (BW). In males, the correlation coefficients in weight trait pairs is 0.6861, and in females is 0.4207. The results showed that with the growth of crabs, weight gain, gonads also increased. Selection of breeding crabs, body weight and spawning rate have a positive correlation.
