The objectives of this study are establishment of genetic stock, mass seed production and cultural techniques of blue swimmer crab Portunus pelagicus. Two batches of blue swimmer crab rearing experiment was carried out in 2012. Average of survival rate of each stage are as fellow: Zoea- 5 stage was 58.67%, Megalopa stage was55.33%, Crab 1 instar stage was 57.7%, Crab 3 instar stage was58.82%, during zoea-1 stage to crab 1 instar stage was18.92%, during zoea-1 stage to crab 3 instar stage was 11.21% respectively. Total of seeds production were185,000 juvenile crabs and 130,000 crabs was transported to 200 tons outdoors pond for nursery ground rearing. After 22 days rearing, juvenile crabs mean carapace width were 17.52-31.54 mm (C8-C10). It was3.1 times as initial mean carapace width(6.96 ± 0.77mm) and survival rate was 38.46％ then releasing into wild sea to increase marine resources in Penghu. Aquaculture and artificial restocking is to restore crabs resources best practices. Blue swimmer crabs growth rapid and resistant diseases can be reared in the pond for monoculture or polyculture, is a promising new candidates of culture.
