摘　　要：在2012年8月进行的南海北部虾拖网海上调查的基础上,对虾蟹类渔获的种类组成、生物学特征和幼体比例等进行了分析。结果显示,渔获种类一共71种,其中虾蟹类15种,但其产量却占总产量的82.34%;虾类优势种为日本囊对虾(Marsupenaeus japonicus)、刀额新对虾(Metapenaeus ensis)、近缘新对虾(M.affinis)和周氏新对虾(M.joyneri);蟹类优势种为红星梭子蟹(Portunus sanguinolentus)、三疣梭子蟹(P.trituberculatus)和远海梭子蟹(P.pelagicus);刀额新对虾的幼虾比例为73.36%,三疣梭子蟹的幼蟹比例为78.79%。最后,探讨了促进南海虾蟹类资源合理利用的措施。We conducted fishery survey in northern South Sea in August 2012 to investigate the composition of shrimp and crab of shrimp beam trawl fisheries. The composition, biological characteristic and ratio of the unmatured were analyzed. The results indicated that there were 71 species, in which there were 15 species of shrimp and crab, accounting for 82.34% to the total output. The dominant species of shrimp were Marsupenaeus japonicus, Metapenaeus ensis, M. affinis and M. joyneri; the dominant species of crab were Portunus sanguinolentus, P. trituberculatus and P. pelagicus; the ratio of unmatured M. ensis was 73.36%, and that ratio of P. trituberculatus was 78.79%. Finally, the measures to rationally use the shrimp and crab resources were discussed.
