水库科学养鱼在我区还是一项较新的水产事业。它既不同于小面积鱼塘的养鱼,又有别于湖泊、泡沼渔业。因此,如何在实践中,根据水库的特点,采取科学的管理措施,对于提高水库的鱼产量有着重要的作用。下面介绍水库科学养鱼的主要技术措施。一、选择鱼类品种我区水库大都为截河或利用低洼地修建而成,原有的鱼类品种主要是鲫鱼及小杂鱼等,需要进行人工投放鱼种来达到增产的目的。水库养鱼应当以放养鲢、鳙鱼为主,鳙鱼数量又要大于鲢鱼。放养这两种鱼,不但可以获得较高的
Reservoir science fish in our district is still a relatively new aquatic project. It is different from fish in small-area fish ponds, but also different from lakes and bubble marshes. Therefore, how to take scientific management measures according to the characteristics of reservoirs in practice plays an important role in improving the fish production in reservoirs. The following describes the main technical measures of fish science reservoir. First, the choice of fish species Most of our reservoirs are cut river or the use of low-lying land built from the original fish species are mainly carp and small trash, etc., the need for artificial fish species to achieve the purpose of increasing production. Reservoir fish should be stocked silver carp, catfish-based, the number of catfish is greater than the silver carp. Stocking these two kinds of fish, not only can get higher
