摘要
根据2011年5-11月舟山沿岸小型建网及定置张网的渔获物数据,结合2种作业渔具结构原理,分析其对渔业资源的利用效率,对幼鱼资源的损害程度。结果表明,张网网目尺寸较小,对幼鱼资源的损害程度较大,小型建网渔具结构设计较合理,对资源更具友好性。建议相关部门对2种渔具科学化管理,正确引导,合理使用。
Based on the catch data of small-scale pound net and stow net in Zhoushan coastal area from May to November, 2011. combined with the structure theory of two fishing gears, analyzing the efficiency to fishing resources and the extent of damage to juvenile resource. The results show that, mesh size of stow net was small, to some extent, which has bad influence on Juvenile resource. The structure theory of small-scale pound net was reasonably designed and more friendly to resource. It suggestsed the related departments rea- sonably assess and scientifically manage the two fishing gears, utilizing them correctly.
