1.清塘消毒选择生石灰清塘消毒,用量为每667平方米75~100千克,方法是加水化浆后全池泼洒,以杀灭病原体及野杂鱼。生石灰消毒不仅能起到调节p H、改良底质的作用,为鱼类生长创造良好的生长环境,而且还能增加养殖水体中钙离子的含量,满足鱼类生长对钙质的需求。2.养殖模式坚持突出主养、科学配养的原则,一般主养鱼占70%~80%,配养鱼占20%~30%,当主养鱼确定后,根据实际情况科学搭配混养鱼种,是为了充分利用养殖水体中的浮游生物等天然饵料,以提高单位面积养殖产量,增加养殖效益。因此,搭配鱼种应视主
1. Qingtang disinfection selection Clear lime Tong disinfection, the amount of 75 to 100 kg per 667 square meters, the method is to add Quanzhonghua after slurry, to kill pathogens and wild trash fish. Quicklime disinfection can not only regulate p H, improve the role of sediment, to create a good growth environment for fish growth, but also increase the content of calcium ions in aquaculture water to meet the fish growth of calcium needs. 2. Breeding mode Adhere to the principle of primary support and scientific support, the general main fish accounted for 70% to 80%, with 20% to 30% of the fish, when the main fish to determine, according to the actual situation with science mixed fish In order to make full use of natural food such as plankton in aquaculture water, it is necessary to raise the yield per unit area and increase the breeding efficiency. Therefore, with fish species should be the main
