| 摘 要： | 蟹类是福建海区重要的经济渔获种类之一。本文基于2009年1月-011年12月期间进行的蟹类调查资料，分析了福建中南部近海四种捕捞作业渔获物中蟹类的种类组成和分布特点。结果表明：福建中南部近海海域有蟹类94种，隶属16科、53属，以亚热带和热带的暖水性种为主，与南海关系最为密切，而与黄、渤海关系较为疏远。从蟹种分布区域看，这些蟹类在浅海均有分布，其中26．6％的蟹类既分布于浅海又分布于潮间带。从蟹种个体大小看，福建海区蟹类多数属于中小型种类。高强度捕捞加剧了对蟹类资源的破坏，因此需要调整捕捞作业结构，拓展外海蟹类捕捞作业，开展资源动态监测和苗种放流增殖工作，并实施TAC管理制度。

| Abstract: | Crabs are one of the important economic species in Fujian sea area. Based on the survey data of crabs from January of 2009 to December of 2011, species composition and geographical distribution characteristic of crabs caught by four fisheries in middle and southern part of Fujian coastal waters were analyzed and studied. The results showed that a total of 94 species recorded belongs to 16 families and 53 genera. Most of them were warm water species of subtropical and tropical zones. They were much closer to South China Sea, and a bit far from the Yellow Sea and Bohai Sea. All of these crabs were distributed in shallow sea, while 26.60% of the crabs were distributed both in shallow sea and the intertidal zone. Most crabs in Fujian sea area were belongs to middle and small - sized species. High - intensity fishing led to the destruction of the crab resource. So it was necessary to adjust fisheries structure, develop fisheries in open seas, carry out dynamic monitoring and enhancement and releasing of fishery resource, and implement TAC management system. |
