The natural diet of blue swimming crabs, Portunus pelagicus, was investigated from October 2008 to October 2009 using hand sampling and a crab gill net. The results showed that the major prey items in the stomach contents of P. pelagicus were teleost fish (29.61%), organic matter (20.69%), crustaceans (18.3%) and shelled molluscs (11.46%). Significant differences were found in diet composition between juvenile and mature crabs, between crabs inside and outside the bay and among seasons. In contrast, significant differences were not found between male and female crabs.
2008年10月至2009年10月，利用手工采样和蟹鳃网对远海梭子蟹（Portunus pelagicus）的自然食性进行了调查。结果表明，远海梭子蟹胃内容物中的主要猎物为硬骨鱼（29.61%）、有机物（20.69%）、甲壳类动物（18.3%）和带壳软体动物（11.46%）。幼蟹与成熟蟹之间、海湾内外的蟹之间以及不同季节之间的食物组成存在显著差异。相比之下，雄蟹和雌蟹之间未发现显著差异。
