| 乌梁素海富营养化严重, 已变成以大型水生植物过度生长为主要表征的富营养化湖泊。提出以生态恢复方法进行乌梁素海富营养化治理, 以网围养殖草鱼的办法实现这一思路。2005 ~ 2006 年共进行了89. 33 hm2 草鱼网围养殖试验, 共投放2 龄草鱼种33 261 kg, 产出商品鱼86 600 kg, 净增重53 339 kg, 实现利润503 702元, 投入产出比1B 1. 77; 试验利用水草2 133 560 kg, 转化N、P、K 的量分别为21 229 kg、1 835 kg、8 556 kg, 实现了通过生物治理方法达到延缓乌梁素海富营养化、沼泽化进程的目的, 为其渔业发展探索了一条有效途径。

| The investigations on the basic conditions of Wulinagsuhai lake, showed that the lake had became eutrophic largly due to overgrowth of hydrophyte. Based on these investatition result and research on the control strategy of Wulinagsuhai lake of eutrophication, this paper put forward the ecological restoration strategy of culture hydro- coles, such as culture grass -carp Ctenopharyngodon idellus with enclosure aquaculture, to decline eutrophication in Wuliangsuhai lake. From 2005 to 2006, grass - carp Ctenopharyngodon idellus was stocked in the area of 89.33 hm^2 as enclosure aquaculture. In this experiment, We stocked 33 261 kg seed of grass -carp. As a result of the experiment, the output of commercial fish was 86 600 kg, the net gain was 53 339 kg. It realized the profit of 503 702 yuan with input-output ratio of 1： 1.77. This experiment while transpormed 21 229 kg N,1 835 kg P and 8 556 kg K through culture of grass - carp, feeding on water grass in Wuliangsuhai lake. It realized the advan- tage of retarding eutrophication and swamping of Wuliangsuhai lake through aquatic organism control way, success- fully finding an effective way to develop Wuliangsuhai fishery. |
