| 摘 要： | (歺又鱼)条、贝氏(歺又鱼)条、似(鱼乔)和逆鱼是我国北方养鱼水库中常形成雄厚种群的习见鱼类。本研究查明:这些鱼类生长缓慢,生产效率低,而且与养殖鱼类有食物竞争关系,应属于无益鱼类;这几种鱼都在越冬期(有的还在生殖期)有强烈集群的习性,利用这一习性进行网具捕捞可以有效地控制其种群。

| Abstract: | Four species of minnows, i.e. Hemiculter leucisculus, H.bleekeri, Toxabram-is swinhonis, and Acanthobrama simoni, are most common and often occur in large populations in the fish-farming reservoirs in North China. It was found out in this work that these fishes should be considered as undesirable because of their slow growth, low production efficiency, and competition upon food against the cultured fishes and netting is an effective way to control the population of the minnows,as these fishes all shoal dens... |
