Blue algae inhibitor composition and using method thereof

Abstract

The invention discloses a blue algae inhibitor composition, which consists of an inhibitor A and an inhibitor B, wherein the inhibitor A consists of the following components in part by weight: 1 to 20 parts of erythromycin or derivative thereof, and 80 to 99 parts of sodium chloride; the inhibitor B consists of the following components in part by weight: 20 to 80 parts of calcium dihydrogen phosphate, 10 to 50 parts of enzymolysis soy protein powder and 5 to 15 parts of bacillus powder; and the weight ratio of the inhibitor A to the inhibitor B is 1:4. The blue algae inhibitor composition does not cause death of cultured animals due to anoxia in a process of preventing and treating blue algae bloom of culture water, and can reduce the pollution of heavy metals; meanwhile, the blue algae can be effectively controlled by using the measures of the invention and is not easy to relapse; and when the blue algae inhibitor composition is used once or twice in the culture process, the growth of the blue algae in a pond can be controlled, and the cost for treating the blue algae in the culture process can be remarkably reduced.

Description

technical field [0001] The invention relates to a cyanobacteria inhibitor composition for preventing and controlling cyanobacteria blooms and a use method thereof. Background technique [0002] During the breeding process of aquatic animals, due to the high nitrogen and phosphorus content in the breeding water, the eutrophication is serious, the water temperature is suitable in the middle and late stages of breeding, and the pH of the water body rises, resulting in a large number of blue-green algae and high-density aggregation in the middle and late stages of breeding in the breeding area, and frequent occurrence of algal blooms , causing great harm to aquaculture. The more common algae that can cause water blooms include cyanobacteria Microcystis aeruginosa, Microcystis water blooms, Anabaena, and filamentous green algae. [0003] The impact of cyanobacterial blooms on the environment of aquaculture water mainly includes the following aspects: [0004] 1. Fish do not li...

AI Technical Summary

Problems solved by technology

[0004] 1. Fish do not like to eat cyanobacteria, the algae are difficult to digest, and the utilization rate is low; 2. The mass reproduction of cyanobacteria and the decomposition of dead algae consume a large amount of dissolved oxygen, resulting in anoxic or even anaerobic water bodies, which can easily lead to flooding of aquaculture water bodies 3. After a large number of cyanobacteria die, the algae protein decays and decomposes, which can produce algae toxins, a large amount of hydroxylamine and hydrogen sulfide and other toxic substances that directly harm aquatic animals. The algae toxins accumulated in aquatic organisms may be harmful through the cumulative effect of the food chain. human health;

[0005] 4. Dead cyanobacteria release a large amount of organic matter, which stimulates the growth of chemoheterotrophic bacteria, some of which are pathogenic bacteria to fish, leading to secondary infection of bacterial diseases; 5. When cyanobacteria multiply in large numbers, they emit a fishy smell , affecting the normal function of the water body; 6. The deterioration of the environment causes the death of aquatic animals

[0010] Although chemical algicides have a good algicidal effect in a short period of time, they have non-specific biological toxicity. While killing harmful algae, they also cause toxicity to other non-bloom organisms, and the cost of the agent is high. The maintenance time is short, and cyanobacteria will repeatedly break out after chemical treatment, so the use is limited

[0011] In addition, there are bioalgicides. Although the environmental pollution of bioalgicides is small, the cost of drugs is high, which is not conducive to large-scale popularization.
