Problems solved by technology

Due to insufficient research on fish and shrimp poisoning caused by algae toxins, and the current water quality testing items also have certain limitations, it is difficult to make an accurate judgment on the poisoning caused by some algae toxins
At present, there are more and more detoxification products on the market. It is difficult for farmers to make the right choice when faced with a variety of detoxification products and they are often at a loss. big loss
Algae toxins not only easily cause fish diseases, cause fish and shrimp to refuse to eat or even die, and affect the quality of aquatic products and breeding benefits, more importantly, they can enter the human body through the food chain, posing a serious threat to human health

Abstract

The invention relates to the technical field of microalgae culture, in particular to a microalgae culture medium and a method for degrading algal toxin. The microalgae culture medium is prepared from potassium hydrogen persulfate, sodium dehydroacetate, sodium citrate, tartaric acid, glacial acetic acid, sodium thiosulfate, lactic streptococci, sodium lauroyl glutamate and Tween. The microalgae culture medium can effectively promote rapid growth and propagation of beneficial microalgae, ensure mass propagation of beneficial microorganisms, accelerate decomposition and conversion of organic matters in the aquaculture process, resist erosion of harmful organisms, reduce algal toxins in a water body, and facilitate improvement of the aquaculture environment and promotion of growth of aquaculture products.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to a microalgae culture medium and a method for degrading algae toxins. Background technique [0002] Microalgae are one of the main producers in aquaculture ponds. In the aquaculture industry, there is a saying that water should be raised before raising fish. The color of the aquaculture water body before putting seedlings desired by research and cultivation technicians is light green, that is, the water body formed by microalgae as the dominant species. Microalgae are direct users of harmful substances in aquaculture water. As we all know, with the passage of breeding time, more feces, residual bait, and animal carcasses accumulate in the water, which will eventually directly lead to the increase of ammonia nitrogen and nitrite content, the increase of various stress responses of farmed animals, and the large-scale outbreak of diseases. Possibility increases. Ho...
