  tunas
The examination of stomach contents of large subsurface tunas caught by long-line fishing, as well as of those of micronektonic fishes which they had eaten, allows us to assess the role played by euphausiids in food webs concerning these fishes.
      
Therefore, these fishes, like tunas themselves, appear to display their main feeding activity in the 0 to 400 m water layer and during daytime.
      
On the other hand, fishes which comprise the prey of large long-line tunas, which are not caught by trawls because they are fast swimmers, feed almost solely on species which remain above 400 m in the daytime.
      
The remarkably high metabolic rates of tunas are presumably correlated with their continuous swimming activity and the maintenance of endothermy.
      
Oxygen profiles indicated that the tunas encountered oceanic water masses that ranged most often from 6.8 to 8.6?mg O2 l-1, indicating no limitation due to oxygen concentrations.

The functions of v.Bertalanffy andGompertz and an equation proposed by the author - denoted as "Reziprokfunktion" - are fitted to growth data of tunny (Thunnus thynnus) and North Sea turbot (Scophthalmus maximus).
      
Landings of little tunny tuna are included in Figure 85 as well.

1977年9—11月和1978年5-7月,南海海洋研究所科学调查船《实验》号,在南海中部海域进行了两个航次的海洋综合调查。调查范围为东径110°-118°,北纬12°-16°30′。这两个航次共采集有金枪鱼类仔鱼282尾,经鉴定有黄鳍金枪鱼95尾、长鳍金枪鱼7尾、强壮金枪鱼69尾、金枪鱼3尾、新金枪鱼2尾、金枪鱼属8尾、鲣65尾、鲔7尾、白卜鲔11尾、扁舵鲣3尾和舵鲣属9尾。本文就这些金枪鱼类仔鱼的种类组成、分布特征及其与表层温度、盐度的关系作了讨论。

The present paper deals with the larvae of tuna-like fishes collected aroundwaters of Xisha Qundao of the Nan Hai, during the period in January 1975 to May1976. The larvae and postlarvae of the tunas, tuna-like fishes, were described. Theybelong to Scombridae (Grammatocynus bicarinatus), Thunnidae (Katsuwonus pelamis,Euthynnus yaito, Auxis thazard, Thunnus thynnus, Thunnus albacares, and Thunnusobesous).

The present paper deals with the larvae of tuna-like fishes collected aroundwaters of Xisha Qundao of the Nan Hai, during the period in January 1975 to May1976. The larvae and postlarvae of the tunas, tuna-like fishes, were described. Theybelong to Scombridae (Grammatocynus bicarinatus), Thunnidae (Katsuwonus pelamis,Euthynnus yaito, Auxis thazard, Thunnus thynnus, Thunnus albacares, and Thunnusobesous). The morphology of these tunas larvae were described as will as the ecology andspawning seasons. There is a close resemblance at same body length between larvae of Katsuwonusoelamis and Thunnus thynnus, in the distribution of chromatophores on the ventrallobe of the tail. The head of the former is large and long (about 30-40% of the bodylengthes) but of the latter is small and short (about 29.33-32.93%). They also differfrom each other in the following features:

本文是根据1975年1月至1976年5月,在西沙群岛附近海区采集到的金枪鱼类仔稚鱼标本,进行研究鉴定的结果。共鉴定了双棱线鲅、鲣、鲔、扁舵鲣、金枪鱼、黄鳍金枪鱼和副金枪鱼等7种,作了形态描述,并对它们的分布和产卵期等作了初步探索。

Studies were conducted to analyze the tuna resources of major economic species,and to elaborate the current situation and problems of deep-sea tuna fishery development.And then the importance and imminence of developing our country′s deep-sea tuna fishery are discussed.Finally some countermeasures on how to develop deep-sea tuna fishery are put forward.

从分析金枪鱼类主要经济种类的资源状况着手,阐述了我国远洋金枪鱼渔业的发展现状及存在问题,探讨我国今后发展大洋性金枪鱼渔业的紧迫性、重要性,并进一步提出了发展大洋性金枪鱼渔业的对策。
