摘　　要：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。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:
