What causes white shrimp?
What is the cause of the white shrimp of South America? This problem should be encountered by many friends of the breeding project. Let's solve it together with the editor today.
What is the cause of Penaeus vannamei
The health degree and drug use problems of hepatopancreas will lead to pathological changes in varying degrees. Whether the water quality and weather deteriorated during the culture period, especially whether the vibrio exceeded the standard. Whether prawns are fed with rotten and moldy feed or other liver-damaging foods containing chemical ingredients during culture.
How to solve the problem
1. Disinfect the water body and kill the bacteria, especially Vibrio, by using "Hamburg Blue" and "Vibrio nemesis".
2. Persist in taking "Hanbao EM freeze-dried powder" + "Qi polysaccharide" or "new enzyme peptide immune polysaccharide" to improve the immunity of the body, and then add the liver protection product "Hanbao Baogan liquid" or "Gankangtai" to protect the liver, protect the liver and organize the intestines. Thus effectively inhibit the growth and reproduction of harmful bacteria in the intestinal tract, enhance the immunity of the body, and reduce the incidence.
3. Stabilize the water quality. If the water source is good, adhere to the cultivation of balanced green algae water, that is, it is better to maintain the dense green water dominated by beneficial algae, and the balanced high density beneficial algae water body has a positive preventive effect on "white stool". If there is a shortage of algae, "green algae source" can be used to supplement the source of algae in the water body. If the water source is eutrophication, the algae phase produced is unbalanced, and most of the harmful algae are in the water. In order to reduce the toxicity of harmful algae to shrimp, "cyanobacteria net" or "algal net" should be used to control the density of harmful algae. Reduce or prevent the occurrence of "white stool" caused by phycotoxins.
