金色小沙丁鱼Sardinella aurita(Cuvier & Valenciennes)是暖水性中上层鱼类,在世界渔业中,占有重要的地位,在闽南-台湾浅滩渔场中,为灯光围网的主要捕捞对象,1971年产量居围网总产量的首位,国外学者对其进行过许多研究,Edward等对墨西哥湾某些鲱科鱼类的卵子和仔鱼作了检索指南,Y.Matsuura(1971)研究了巴西金色小沙丁鱼的生活史和鱼卵在里约热内卢的ILha Grande区的分布;此外,D’Ancona(1956),J.G.Simpson和G.Gonzaleg(1967),V.A.Tkachenko和G.N.Semenov(1975)等学者也作了一些研究。有关金色小沙丁鱼鱼卵和仔鱼的研究,国内未见报道,本文研究了金色小沙丁鱼鱼卵和仔鱼的形态特征、生殖季节、产卵场和产卵条件,为确定中心渔场位置和制订繁殖保护措施提供依据。
Small golden sardines Sardinella aurita (Cuvier & Valenciennes) is a warm-water pelagic fish that occupies an important place in the world’s fisheries and is the main target of light seine among the Taiwanese shoal fishing grounds in southern Fujian. Yields in 1971 In the first place of the total output of the net, many studies have been conducted by foreign scholars. Edward et al. Searched the eggs and larvae of some herring families in the Gulf of Mexico. Y. Matsuura (1971) studied the life history of the small golden sardines in Brazil And the distribution of fish eggs in the ILha Grande district in Rio de Janeiro; in addition, studies by D’Ancona (1956), JGSimpson and G. Gonzaleg (1967), VATkachenko and GNSemenov (1975) and others have been conducted. The research about the golden sardine fish eggs and larvae has not been reported in China. This paper studied the morphological characteristics, reproductive season, spawning and spawning conditions of the small sardine fish eggs and larvae. In order to determine the location of the central fishing grounds and to formulate breeding protection Measures provide the basis.
