| 摘 要： | 结合银鲳和小黄鱼流刺网网目选择性试验,对夏季黄海南部沿海三层表层流刺网渔获物组成进行了调查分析.总共鉴定出渔获品种25种,其中优势种为梭子蟹(Portunus triuberbuculatus)、灰鲳(Stomateoidesnozawae Ishikawa)和银鲳(Stromatecoides argenteus),分别占总渔获量的59.2%,21.5%和11%,灰鲳体长分布范围为17～30 cm,优势体长范围为21～24 cm,占71.6%;银鲳体长分布范围为13～23 cm,优势体长范围为15～21 cm,占95.8%.数据分析表明,三重流刺网作业网具选择性较差,渔具兼捕种类多,捕获量大,占总渔获量的66.5%;渔获的灰鲳和银鲳处于生长型捕捞期,不利于资源的可持续利用,建议适当改良渔具,避免对其资源造成过度破坏.

| Abstract: | Combining with the selectivity research of gill-net,the authors investigated the catches' components of floated-trammel net used by gill-net fishery in the south region of the Yellow Sea,and discriminated 25 species from catches,the dominant species is swimming crab,silver butter-fish and Silvery pomfret,the weights of the three species take account for 59.2%,21.5% and 11% of the total production respectively.The length ranges of silver butter-fish are among 17~30 cm,the dominant ranges are 21~24 cm and tak... |
