闽南粤东近海金色小沙丁鱼的生物学及其渔业

ON THE BIOLOGY AND FISHERY OF THE GOLDEN SARDINE SARDINELLA AURITA VAL. FROM THE COASTAL WATERS OF SOUTHERN FUJIAN AND EASTERN GUANGDONG PROVINCES

金色小沙丁鱼为暖水性中上层鱼类,广泛分布子三大洋的温暖海区及我国南海和东海南部。随着灯光围网渔业的发展,六十年代后期金色小沙丁鱼已成为闽南粤东海区的主要渔获对象,在福建海洋渔业中占有重要地位。1971—1974年福建中上层鱼类调查组曾对它和蓝圆鲹等中上层鱼类进行多年调查研究。下面谨将关于金色小沙丁鱼的调查结果结合个人的一些研究综合成文,供水产学界同志参考。一、闽南粤东近海金色小沙丁鱼的生物学(一) 体长组成闽南粤东渔场金色小沙丁鱼春汛生殖群体的又长范围大致在160—260毫米之间,几年来的变动不大。

Summerized here are the investigations on the biology of the golden sardine,Sardinella aurita Val.from the coaostal waters of the Southern Fujian and Eastern Guangdong provinces.The subjects smdied are:length,weight and age composition,growth,age and length at the first sex maturation,spawning season and spawning ground,sex ratio and fecundity,food composition and feeding intensity.The interrelationship between the changes of certairn biological.peculiarities arid resources of the sardine as weU as recent fluctuations of the sardine fishery has been discussed.
