福建九龙江口近海定置作业渔获物组成及其数量变动的调查研究

Preliminary study on species composition and its amount fluctuation of set-net catches in Jiulongjiang Estuary, Fujian

本文自1999年12月～2000年12月对福建省九龙江口近海定置作业渔获物种类组成及其数量变动进行周年调查.经分析渔获物经济种类有99种,其中鱼类65种,甲壳类28种,头足类6种.作者认为调查海区定置作业周年中,在5～8月对经济种类的幼体有很大的伤害.为此建议渔政管理部门适当延长休渔期,并着重对定置作业的船数和网具数进一步予以限制,尤其是对网具结构及作业方式进行改革,籍以保护渔业资源.

The investigation and analysis of the species composition andamountfluctuation of the catches of set-net in Jiulongjiang Estuary, Fujian had beenmade in Dec.1999 to Dec.2000.There were 99 economicspecies from the catches,including 65 species of fishes,28 species of crustacean and 6 species of cephalopod .Annual survey of the catches of set-net in those areas showed that the youngstage of the economics species were cruelly damaged in May ～ September. In order to protect the stocks, we suggested the Fisheries management department to revise the regulation, such as to prolong the fishing off season, to restrict the number of set-net operation boat and the gear behavior, especially to reform the structure of set-net and their operating methods.
