摘　　要：本文根据2003～2004年张网作业的监测调查资料,研究分析了闽南海区张网作业渔获物组成。结果表明,闽南海区张网渔获种类多达156种,主要渔获种类为带鱼、康氏小公鱼、尖尾鳗、二长棘鲷、静、蓝圆和中华管鞭虾等14个类群组成,其渔获量合占总渔获量的79.5%;张网作业对闽南海区经济种类的损害较为严重,经济幼鱼、幼体在渔获物中所占的比重达39.3%,尤以张网禁渔期前后的3～4月和7月,经济幼鱼、幼体受损最为严重,其比重高达52.8%～74.0%。据估算此期间全海区张网作业损害带鱼、二长棘鲷、鲐鱼幼鱼1.12×104t,数量高达17.12×108ind。因此,建议在加强张网作业周年监测调查基础上,考虑适当调整或延长禁渔期,以利于渔业资源的合理利用。According to monitoring data of swing net fishery in Southern Fujian sea waters from 2003 to 2004, the catch composition was studied. The results showed that there were 156 species in the catch, among them 14 species were the main species such as Trichiurus haumela, Stolephorus commersoni, Uroconger lepturus, Paragyrops edita, Leiognathus insidiator, Decapterus maruadsi, Solenocern crassicornis, which accounting for 79.5% of the total catch. The swing net injured economic species seriously, in which the economic juvenile representing 39.3% of the catch, especially in March, April and July with 52.8% to 74.0%. A total of 1.12×104t juvenile(17.12×108 individuals) of Trichiurus haumela, Paragyrops edita, Pneumatophorus japonicus and Decapterus maruadsi was estimated to be injured by swing net during that period. Therefore, this paper suggested that the closed season be properly adjusted to benefit the utilization of the fishery resources on the basis of strengthening the monitor of swing net.
