台湾海峡中南部海域光诱敷网渔业资源监测

本文根据2007—2008年台湾海峡中南部海域光诱敷网渔业监测调查资料，分析该渔场光诱敷网渔业利用状况及主要渔获种类资源动态。监测调查结果表明：光诱敷网作业生产汛期为6—10月，旺汛期6—8月；监测调查船年总渔获产量85～88t，主捕种类枪乌贼、鲐鱼、金色小沙丁鱼的渔获量分别约占总渔获量的35％、30％和20％。枪乌贼、鲐鱼、金色小沙丁鱼均属于生命周期短，生长快，资源补充量大的中上层种类，是多种作业的主要利用对象，目前枪乌贼、鲐鱼资源现状仍然保持相对良好，但在强大捕捞压力下，容易捕捞过度引起年间渔获量大幅度波动，因此对其资源应加以保护。

Survey of Fisheries Resources by Light-liftnet in Central and Southern Taiwan Strait Fishing Ground

Based on survey data by light - liftnet in central and southern Taiwan strait fishing ground during 2007 - 2008, fishery utilizing status and stocks development of main species were analyzed. The results showed that： the season of fishing by light - liftnet was from June to October, and the best fishing period was from June to August; annual yield of monitoring ship was 85- 88t, with mainly catching Loligo, Scomber japonicus and Sardinella aurita, accounting for 35%, 30% and 20%, respectively. Loligo, Pneumatophorusjaponicus and Sardinella aurita, which are mainly catching species by several fishing methods, are pelagic species, with characteristics of short life period, rapid growth rate and large resources recruitment. Fisheries resources of loligo and Pneumatophorus japonicus are in a relative good state now. But as a result of large yearly catch fluctuation under serious fishing pressure, they should be protected.
