Abstract	This pioneer study on the captive broodstock breeding of the mud crab (Scylla paramamosain) consisted with a series of experiments. The larvae rearing trial was fed with Artemia umbrella, enriched rotifer and rotifer from Z1 to Z2 stages followed by Artemia nauplii, enriched Artemia nauplii and commercial diet, respectively from Z3 to megalopa. Highest larval stage index (LSI), significantly higher (p<0.05) megalopa and crablet survival was achieved from enriched rotifer followed by enriched Artemia feeding schemes that had the eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), n-6 to n-3 and EPA to DHA ratios of 17.32%, 3.82%, 0.20 and 0.22, respectively in megalopa for subsequent metamorphosis to crablet. Growth of mud crab displayed the sigmoid pattern for both sexes with significantly higher (p<0.05) weight gain in males. The female mud crab grew faster (p<0.05) in outdoor tanks, but survival and the proportion of intact crabs were higher (p<0.05) under indoor compartment and outdoor floating boxes. The male crabs attained sexual maturity following spermatogonia, spermatocytes and spermatozoa, whilst, the females completed gonad maturity through proliferation, previtellogenesis, primary vitellogenesis, secondary vitellogenesis and tertiary vitellogenesis. The first sexual maturity appeared at 5 months and 5 to 5.5 months for male and female crabs, respectively, after settlement as crablet. The median maturity age (MA50) was 6.5 months and 6.5 to 7 months for male and females, respectively. Faster maturation in male, asynchrony in intra-sexual and simultaneous intersexual maturation was
