Water quality improver for aquaculture, and preparation method thereof

Abstract

The invention discloses a water quality improver for aquaculture. The water quality improver comprises, by weight, 5-17 parts of iron-modified montmorillonite, 20-50 parts of peanut meal, 5-15 parts of corn flour, 6-18 parts of wheat bran, 2-5 parts of EM bacteria, 5-13 parts of yeast extract, 10-20 parts of Chinese herb medicines, 3-11 parts of nitrifying bacteria, 1.5-3.5 parts of tea seed cakes, 2-8 parts of acetylcholinesterase, 0.5-0.9 part of selenium, 3-11 parts of chitosan and 2-8 parts of an antifoaming agent. The invention provides the water quality improver for aquaculture, and a preparation method thereof. The preparation method is simple, and the water quality improver improves water quality purification, increases the fertility of water, reduces the content of harmful substances in the water, such as insecticides and disinfectants, and reduces the incidence of aquatic animals.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a water quality improver for aquaculture and a preparation method thereof. Background technique [0002] In aquaculture, water quality problems often become one of the limiting factors for the sustainable development of aquaculture. In the aquaculture industry, the aquaculture waters contain a large amount of residual feed, fertilizers, excrement of aquatic products, organic matter and bacteria, which increases the proportion of ammonia nitrogen in the water. At the same time, the ammonia nitrogen organic matter in the aquaculture water turns into ammonia nitrogen, then into nitrite nitrogen, then into nitrate nitrogen, and finally into nitrous acid. The nitrous acid in the water will poison the aquatic products in the water. At the same time, ammonia nitrogen organic matter, nitrous acid, etc. can easily cause water quality damage, and pathogenic bacteria multiply, affect...

AI Technical Summary

Problems solved by technology

At the same time, the organic matter of ammonia nitrogen in the aquaculture water turns into ammonia nitrogen, then into nitrite nitrogen, then into nitrate nitrogen, and finally into nitrous acid. The nitrous acid in the water will poison the aquatic products in the water. At the same time, ammonia nitrogen organic matter, nitrous acid, etc. will easily cause water quality damage, and pathogenic bacteria will multiply, affecting the output of aquatic products and greatly reducing the quality of aquatic products.
