清野除害搞的好坏,直接影响到水库人工放养鱼种的成活率,在当前我县放养规格偏小的情况下(一般为2.5~3寸),这个问题显得十分突出。因此及时清除水库中的害鱼(鲶、黄(鱼桑)、自鳝、马口鱼等),控制它们在水库中群体的数量,对提高人工放养鱼种的成活率和水库鱼产量,都有十分积极的意义。近两年来,我们在鲶鱼、黄(鱼桑)鱼较多的尹府水库利用食钩钓鲶鱼、黄(鱼桑)鱼,获得了成功。每天下250把食钩,春季日产量一般为20~30斤,最高日产量为35斤左右;秋季日产量一般为15~20斤,最高日产量为26斤。现将其渔法介绍如下:
Qing Ye removal of good or bad, a direct impact on the survival rate of artificial fish stocking reservoirs in the current stocking specifications of my county is small (usually 2.5 to 3 inches), the problem is very conspicuous. Therefore, the timely removal of harmful fish in the reservoir (catfish, yellow (fish mulberry), self-eel, mackerel, etc.) to control their population in the reservoir, to improve the survival rate of artificial stocking and reservoir fish production, both Have a very positive meaning. In the past two years, we succeeded in catching fish catfish and yellow fish with Yin (catfish) and yellow (fish) fish at Yinfu Reservoir. Daily under the hook 250, spring daily output is generally 20 to 30 pounds, the highest daily output of 35 pounds; autumn daily output is generally 15 to 20 pounds, the highest daily output of 26 pounds. The fishery law is now introduced as follows:
