中文摘要:
      用实际种群分析法评估了工海及长江口区域鲐鱼近10年来的现存资源量,结果表明,工海及长江口区域的鲐鱼自1997年以来历年的现存资源量分别在13.2-23.5万吨和4.1-12.7万吨之间波动,近年一资源数量稳定在一个较高水平上,而近年鲐鱼的实际捕捞已逐渐接近其现存资源量,说明鲐鱼资源进一步开发利用的潜力不是很大。
英文摘要:
      Stock sizes of the chub mackerel (Scomber japonicus)from the East China Sea and the area off the mouth of Changjiang r iver were assessed with vir tual populat ion analysis .The r esult showed that stock sizes of chub mackerel fr om the East China Sea and the area off the mouth of Changjiang River were fluctuated between 132 000 -235 000 and between 41 000 -127 000 me tric tones respectively in the past decade .The stock sizes of chub mackerel in recent years were stable on the r elat ively high levels .However , since the actual catches are gradually close to the stock sizes , it seems tha t there is not very much potential for f urther exploitat ion of this species .
