张星桥水库三年来鱼产量下降,主要原因是由于翘嘴红繁衍过快。本文根据翘嘴红的生物学特性,分析提出了扦捕和药物清库两种措施。为达到根治目的,着重分析了采用生石灰进行清库的方法;清库时间在11月上中旬为宜;实施清库时对鱼种的保护,要求采用良好的捕捞方式,准备足够的暂养池。并预测清库的后果是;将形成以中上层经济鱼类为主的生态平衡;水质变肥,鱼的生长加快;三年后鱼产量开始回升。
Zhang Xingqiao reservoir fish production decreased over the past three years, the main reason is due to Alice red reproduction too fast. In this paper, according to the biological characteristics of Alice lipstick, we analyzed and proposed two measures: harvesting and drug clearing. In order to reach the goal of cure, the method of using clear lime for clearing the reservoir was emphatically analyzed; the time for clearing the reservoir was suitable in the middle and upper reaches of November; the protection of the fish species during the implementation of the reservoir cleaning required the adoption of a good fishing method and the preparation of adequate holding tanks . And predict the consequences of clearing the reservoir is; will form the economic balance of the upper middle class of fish; water quality changes, fish growth accelerated; three years after the fish began to rise.
