Abstract:The article investigates the biology of Portunus pelagicus Linen Beibuwan Bay Hainan Isiand. It shows initially that the sex ratio of the year is nearly 1∶ 1. The cards′ mating season period is August to October or June to August. The cards at first maturity were 75 mm in carapace width and 48 g in body weight. A great number of maturity were 100- 120 mm in carapace, width and 70- 100 g in body weight, except the spawning period is very long with two high spawning period the year round. It takes place in March to May or August to October Month. The cards′ dominant groups of the carapace width and body weight are 110- 150 mm and 60- 150 g.
Keywords:Portunus pelagicus  Biology  Beibuwan Hainan Island
