摘要
本文研究了黄河三角洲主要经济鱼种—安氏新银鱼Neosalanx anderssoni和居氏银鱼Salanx cuvier的形态特征、种群结构、繁殖习性、食性、生长特性及洄游分布等生物学特征;同时记载了银鱼主要产卵场——淄脉沟的环境条件,分析了该地区银鱼资源衰退的原因,提出了恢复和发展黄河三角洲银鱼渔业的措施。
The Zimaigou River is the spawning ground for main fishery species, Neosalanx anderssoni and Salanx cuvier,of the Yellow River Delta. Monthly survey on the fisheries biology of both species were conducted in the river for two consecutive years. This paper deals with the study on the two species in morphology,population structure,breeding and feeding habit,growth and migration behavior as well as the environmental conditions of the area. An analysis was made of the causes of the decline of the species resources and measures of fisheries management to revive the industry were advanced.
