摘  要：
根据2003年2月至2006年12月对29°30′～32°00′N,122°30′～125°30′E东海北部浅海海域的调查资料,研究了头足类数量的时空分布和各类种类组成。结果表明:头足类资源群落结构发生了较大变化,鱿鱼成为头足类的优势种,6月为其捕捞高峰期,密集分布区在长江口渔场的东部;其次为章鱼类,其高峰期出现在5月和9月,密集分布区在舟山渔场东南部;乌贼比例最低,每年渔获量不超过5%,基本形不成渔汛。为今后更好地持续利用长江口渔场和舟山渔场的头足类资源,建议春、冬季对其进行保护,夏季高峰期重点开发;在拖网伏休的7、8月份可采用光诱作业和鱿钓等作业方式进行利用。

摘  要：
Based on the investigating data in the shallow sea fishing ground of the northern East China Sea(29°30′～32°00′N,122°30′～125°30′E) from February in 2003 to December in 2006,the space-time quantity distribution of cephalopod was studied.The results showed that the community structure of cephalopod has changed.The squid is the dominant species,mostly distributing in eastern Yangtze River estuary fishing ground and its capture fastigium period is in June.The octopus is the second,with capture fastigium period in May or November and mostly distributing in southeastern Zhoushan fishing area.With no more than 5% capture in recent years,cuttlefish is the lowest one which can not engender fishing season.In order to make good use of cephalopod resources continuously,it is suggested that they should be protected in Spring and Winter,and caught in summer.The lighting inducement and squid jigging can be used for catching cephalopod resources in June and August when trawl net fishing is forbidden.
