吉林省西部的大中型湖库，绝大多数为草型湖库，由于草食性鱼类放养不足，使得水草资源得不到充分利用，甚至对湖库渔业构成危害。目前，草食性鱼类 (草鱼、团头鲂等 )的养殖规模小、产量低，远不能满足草型湖库对草食性鱼种的需求。为了进一步完善精养草鱼种技术、提高草鱼种 The large and medium-sized lake banks in the west of Jilin Province are mostly grass-type lakes and reservoirs. Due to insufficient stocking of herbivorous fish, the resources of aquatic plants are not fully utilized and even pose a hazard to the fisheries of the lakes and reservoirs.

In order to further improve the intensive grass carp technology, improve grass carp species
