Water quality improver for aquaculture

Abstract

Relating to the technical field of aquaculture, the invention provides a water quality improver for aquaculture. The water quality improver comprises the following raw materials by weight: 8-15 partsof straw, 4-8 parts of lignin, 3-6 parts of sodium humate, 10-15 parts of polyacrylamide, 6-13 parts of chitosan powder, 4-9 parts of gram-positive actinomycetes, 4-9 parts of photosynthetic bacteria,2-6 parts of bacillus, 5-10 parts of lactic acid bacteria, 5-10 parts of bacillus natto, 7-14 parts of saccharomycetes and 6-18 parts of a Chinese herbal medicine additive. The water quality improvercan effectively improve the water quality of water in aquaculture, promote propagation of aquatic organisms and increase the survival rate, and meanwhile, the preparation method of the water qualityimprover is simple and easy to master, thus facilitating promotion.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a water quality improver for aquaculture. Background technique [0002] Water, species and bait are the three major material bases of aquaculture. Ponds with good water quality can not only reduce the occurrence of diseases, but also reduce the feed coefficient and improve the economic benefits of breeding. Therefore, to a large extent, aquaculture is water cultivation. As long as the water quality management is done well, the success of aquaculture will be more than half. However, in recent years, with the rapid development of aquaculture and the deepening of intensification, the pollution of aquaculture water is becoming more and more serious, the water environment is deteriorating, and diseases occur frequently. series of environmental and social issues. The deterioration of water quality has become the main reason restricting the development of aquaculture. [0003] P...

Problems solved by technology

In the water used for aquaculture, the sources of water quality hazards are not only harmful metal ions, but also include: 1) Reduction of dissolved oxygen in the water: Excessive reduction of dissolved oxygen in the water will cause fish not to like to eat, and in severe cases may even cause A large area of ​​death occurs; 2) The pH value of the water is unbalanced: the pH value of the water body is too low and acidic, which will reduce the oxygen carrying capacity of the fish itself, resulting in hypoxia and "floating head", and the pH value is too high and alkaline will make fish The gills of fish are severely corroded, causing large areas of death; 3) Excessive content of nitrite, ammonia nitrogen, hydrogen sulfide and other substances will cause slow metabolism of aquatic organisms such as fish and affect growth; 4) Excessive reproduction of cyanobacteria will cause Lead to the reduction of dissolved oxygen in water and heavy metal pollution, etc.
