湖鲚(Coilia ectenes Taihuensis Yuan et Lin)是太湖的重要捕捞对象,其年产量约占太湖总产量的50％左右,1983年达14.11万担。因此,历来受到渔业科学工作者的重视,对湖鲚进行了多次调查与研究,并著有专题报告。但对其产卵鱼群的组成与变动及繁殖发育规律等尚缺乏详细资料。为逐步改变太湖鱼类种群结构和合理利用湖鲚资源提供科学依据,作者根据1983年湖鲚周年生物学测定资料,对太湖湖鲚生殖特性进行分析与探讨。
Lake Tai (Coilia ectenes Taihuensis Yuan et Lin) is an important fishing target of Taihu Lake, its annual output accounts for about 50% of the total output of Taihu Lake in 1983 reached 141,100. Therefore, it has always been valued by fishery scientists and has conducted many investigations and studies on the lake and conducted special reports. However, there is a lack of detailed information on the composition and variation of spawning fish and the law of breeding and development. In order to provide a scientific basis for gradually changing the structure of fish population in Lake Taihu and making rational use of the resources of Lake Loudi, the author analyzed and discussed the reproductive characteristics of Taihu Lake based on the data of the 1983 annual biological measurement.
