Which fish farming bodies should not use lime

Quicklime is a commonly used substance in the prevention and improvement of water quality in current fishery production. The rational application of quicklime in some fish cultures can neutralize excess acid, precipitate toxic metal ions, kill fish pathogens, promote the condensation and decomposition of organic matter and suspended matter in water, reduce oxygen consumption, and improve water productivity. positive effects. However, there are some places that have abused quicklime for ignoring the specific conditions of water quality, resulting in reduced production.

So, which types of water should not use lime? Generally speaking, there is already a large amount of calcium ions in the water and sediments, and lime in the alkalinity ponds should not be used. Since lime is applied again, the phosphate precipitation is fixed more and more completely, and the concentration of available phosphorus in the water is reduced, resulting in lack of water bodies. Phosphorus affects or even limits the growth of aquatic plants, resulting in low yield of fish culture. In addition, some organic matter in the water body is insufficient (such as newly excavated fish ponds). If lime is used alone, the organic matter will be intensified and the fertility will be further reduced, which will also result in low yield. The prevention method is: Before the use of quicklime in aquaculture water, the total acidity and total hardness of the water body should be tested, and it should be known that the thin water body should use organic fertilizer or phosphate fertilizer while using quicklime.

Protective immunity

Zinc enhances immunity
Zinc is only 0.003 percent of your body weight, or about 10 grams in an adult's body. 90% of zinc is stored in muscle and bone, while the remaining 10% plays a critical role in blood.
Zinc is one of the microelements in the body. In recent years, the most eye-catching one is the function of zinc in immunity. Human zinc deficiency, there will be a number of lymphocyte depression, reduced blood immunoglobulin, natural antiseptic function abate, skin immunity test reaction reduce metabolic problems, as a result of clinical pneumonia, beads coccus infection, even the common cold, at ordinary times can take some preparations of zinc supplementation to complement in time, improve their immunity.
