Water quality improver for aquatic production and preparation method thereof

Abstract

The invention provides a water quality improver for aquatic production and a preparation method thereof and relates to the technical field of aquatic cultivation; the water quality improver is mainly prepared from, by weight, 25-35 parts of amino acid organic matters, 10-20 parts of plant ash, 10-15 parts of Saccharomyces cerevisiae, 5-15 parts of corn meal, 0.5-1.5 parts of molasses, 0.5-1.5 parts of a complex microbial bacterial agent, 0.5-1.5 parts of a complex vitamin preparation, and 0.5-1.5 parts of medium- to trace-element preparation. The water quality improver has the advantages that the technical problem that deteriorating quality of existing pond water seriously affects the growth of aquatic animals and causes damage to human health is relieved; the growth of algae and plankton can be promoted, water quality is improved, and productivity of a water body is improved; the contents of ammonia nitrogen and nitrites in the water body can be decreased, the proliferative growth of harmful bacteria is inhibited, the survival rate and yield of breed aquatics are increased, and damage to human health is avoided,.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture water quality improver and a preparation method thereof. Background technique [0002] In recent years, my country's aquaculture industry has developed by leaps and bounds, and it has become a large fishery country in the world with aquaculture production exceeding fishing production. Most of the existing aquaculture industry in my country adheres to the traditional farming model characterized by "dense, mixed, and round" technology, that is, a farming model that obtains high yields with multi-species, high density, and large-scale fertilization and feeding. In order to increase the aquaculture output per unit water body, water body nutrients are often excessively increased, excessive baiting, fertilization and increasing stocking density, resulting in a large amount of residual bait and metabolites of cultured species accumulating at the bottom of the pond, de...

AI Technical Summary

Problems solved by technology

In order to increase the aquaculture output per unit of water body, water body nutrients are often excessively increased, excessive baiting, fertilization and increasing stocking density, resulting in a large amount of residual bait and metabolites of cultured species accumulating at the bottom of the pond, deteriorating water quality, decreasing dissolved oxygen, and ammonia nitrogen. Harmful substances such as nitrite and hydrogen sulfide increase, chemical oxygen consumption (COD) and biological oxygen consumption (BOD) increase, which seriously affects the growth of aquatic animals, causing osmotic pressure imbalance, stress, and immunity in aquatic animals. Decrease in force, which will easily lead to explosive death of aquatic animals and affect the quality of animals, causing indirect harm to people's health
