Variations in age and size at sexual maturity of female green mud crab (Scylla paramamosain) under different captive growout conditions


Author(s): Md. Latiful Islam and Khairun Binte Yahya

Abstract: Sexual maturity of female green mud crab (Scylla paramamosain) under different grow out protocol was assessed by evaluating the composition of different gonad development stages in respect to age and size. Female crabs attained sexual maturity following five gonad development stages of proliferation, previtellogenesis, primary vitellogenesis, secondary vitellogenesis and tertiary vitellogenesis. First sexual maturity initiated at 110.40, 112.60 and 116.80 g of body weight and 7.10, 7.30 and 7.90 cm of carapace width under indoor compartment, outdoor boxes and outdoor tanks, respectively. After settlement as crablet, the first sexual maturity appeared at 5 months of age under outdoor tanks and 5.5 months for outdoor boxes and indoor compartment. The median maturity age (MA50) was 6.5 months for outdoor tanks and 7 months for other two protocols. Earliest commencement of sexual maturity and production of larger sized highest number of gravid females in outdoor tank culture system suggested as suitable over other two protocols.
