中文摘要:
      本文对东海主要渔场中带鱼 Trichiurus lepturus Linnaeus 的摄食习性、饵料浮游生物的群落结构及数量分布等进行了阐述和分析,并对其与渔场间的关系进行了探讨。研究结果表明,东海带鱼是一种以磷虾等甲壳动物和小型鱼类等为主食,并兼食头足类、毛颚动物等的杂食性鱼类。研究结果还阐明浮游动物生物量及磷虾等的数量分布同东海带鱼渔场的位置变化和鱼群移动的关系密切,其中冬、春季浙江南部近海渔场;夏、秋季长江口及海礁、舟山等渔场,其关系尤为明显。
英文摘要:
      A study on the feeding habit and food basis of hairtail fish (Trichiurus lepturusLinn.) as well as the relationship between its food organism and fishing grounds hadbeen carried out during the years from 1960 to 1981. Food organisms and stomachcontent samples were collected from some fishing grounds along the coastal waters ofZhejiang Province and off the Chang Jiang estuary during 1963--1965.The results are as follows:1. Hairtail fish is omnivorous mainly feeding on planktonic crustaceans (Eupha-usiacea etc.) and also fishes, Cephalopods, Chaetognaths etc.2. The Euphausiacea resource of the Dong Hai region is very abundant. Thequantitative distribution of the shrimp seems verey closely related to the migration ofhairtail.It obviously manifests in some fishing grounds along the southern coastal waterof Zhejiang province in winter and spring seasons and also occurs at the mouth ofChang Jiang in summer and autumn.3. The present paper deals with the analyse of the structure of plankton com-munities in some fishing grounds and the discussion of the relationship with the move-ment and migration of hairtail fish.
