闽南、台湾浅滩渔场单拖作业渔获物组成分析

The Catch Composition Analysis of Single Trawler in Minnan and Taiwan Bank Fishing Ground

根据2000～2001年单拖作业渔获物调查资料，着重对渔获物种类组成、个体大小进行分析。结果表明：闽南、台湾浅滩渔场单拖网作业渔获物品种繁多、个体小，优势种数量多、比重小，占周年总渔获量1％以上的品种有19种，鱼类、甲壳类、头足类渔获个体平均体重仅为11．4g／ind，周年中，5～6月个体最小，建议将该渔场单拖作业伏季休渔时间调整为5月1日至7月15日。

According to the investigating data of the single trawler during 2000 to 2001, this paper analyzed and studied the catch composition and individual size. The results showed that the catch species of single trawler are various, and the individual size is small, There are 19 species occupying 1% of the total yield. The average body weight of fish, crustacean and cephalopod is merely 11.4g. The body size is least in May to June during the year. This paper suggested the closed period of single trawler should be adjusted from 1st May to fifth July in the fishing ground.
