1. Improvement of bottom sediment quality in dredging the entire pond (1) Dredging: Using this winter and next spring, aquatic products are drained after harvesting, and the sludge is removed mechanically or manually from the pool, and the solar pool is sealed to accelerate the oxidative decomposition of organic matter. (2) Sun bath: After the dredging, the sun bath can be used. Generally, the water can be released 20-30 days before the shoot is released. (3) Liqueurants such as quicklime and other clear ponds are used, and clear ponds are selected according to the actual conditions of the cultured species, such as quicklime, bleaching powder or teaseeds, and teaseed substitutes, etc. Never use highly toxic and high-residue drugs and the finished products. Drugs were stopped 45 days before listing.
Second, improve the environment to improve water quality (1) grass cast snail (crab pool) to create an excellent ecological environment. (2) Add water and change water to keep the water fresh. (3) The use of viable microorganisms to enhance the disease resistance of aquaculture products. Reduce the use of organic medicines. In the finished product breeding stage, the use of exotic drugs such as malachite green and nitrites is prohibited.
Third, rational stocking scientific management (1) depending on the rational allocation of cultured species, reasonable density, to achieve effective and full use of water, the use of resources. (2) Observe regularly, grasp the situation, prevent the occurrence of diseases, and reduce the amount of drugs. (3) Do a good job of recording (water temperature, pH, specific gravity, transparency, etc.), and find problems in a timely manner.
Fourth, the preferred food guarantees nutrition. (1) Cultivate basic feed, apply nitrogen fertilizer, phosphate fertilizer, calcium fertilizer, etc., and cultivate basic bait algae algae and small plankton beneficial microorganisms. (2) According to different stages of breeding, reasonable collocation and reasonable feeding. (3) Selection of high-quality compound feeds for scientific feeding and ensuring nutritional requirements. It is strictly forbidden to use hormonal additives or formulated feeds containing hormonal additives.
