摘要
新丰江水库1998年移植太湖新银鱼受精卵后,1999-2000年能捕到大量子一代,子二代的银鱼,但未形成产量。分析了该水库生态环境与银鱼移植增殖的关系及影响种群形成的原因,提出了提高移植银鱼效果的建议。
Fertilized eggs of Neosalanx taihuensis were introduced into Xinfengjiang Reservoirin 1998.Quanti- ties of F1 and F2 fish were harvested during 1999-2000.There relationship between ecological environment and ice-fish transplantation and proliferation,and the reason attecting the population were analysed.Recommen- dations to promote ice-fish transplantation effects were raised.
