摘　　要：本文根据1998～1999年在闽东北外海进行四个季度月的蟹类资源定点调查及相关资料,研究调查海区蟹类种类组成。结果表明:本调查海区蟹类组成有51种,隶属11科34属,以暖水性种类为多,具有热带与温带群落之间的过度性混合群集特点,主要渔获种类有细点圆趾蟹、光掌蟳、锈斑蟳等10种;其中细点圆趾蟹是本调查海区最主要渔获种类,主要分布于水深100～120m的海域,渔获量占蟹类总渔获量的54.4%,尚有一定资源潜力,待于合理开发利用。Based on four season survey data for crab resource from 1998 to 1999 in Northeast Fujian Outer Sea and some related material, this paper studied the crab species composition in the area. The result shows that a total of 51 species of crabs which belong to 34 genera, 11 families is found in the area over the survey period. The warm water species are dominant among them, which have some community characters between the tropic and temperate zone. There are more than 10 species including Ovalipes punctatus, Charybdis riversandersoni, Charybdis feriatus, etc that are high commercial value, among which Ovalipes punctatus is the most commercially important species in the area. They mainly distribute in the area with the water depth between 100 to 120 m. The catch of Ovalipes punctatus usually accounts for (54.4%) of total catch. The resource of Ovalipes punctatus in this area still is good potential and should be rationally exploited.
