In the middle and late period of freshwater culture of Penaeus vannamei, "stealing death disease" appeared, and the water quality was turbid: how to deal with high nitrite and how to solve it are in urgent need of answers. Thank you for your help. An effective method for preventing and treating latent death of prawn caused by Vibrio parahaemolyticus. This is a common view, of course, it also needs to be based on the actual situation of your breeding, and you can't blindly believe the report.

The turbidity of water quality is probably due to your high stocking density, or it may be due to too much change of adsorption soil, which leads to the rupture of flocculation layer at the bottom of the pool.

There are many reasons for high nitrite. Generally, the stocking density is high, or the water turns, even if it rains, algae death is likely to lead to an increase. It is best to prevent it in advance.

If your prawns are still eating secretly, reduce the feed appropriately, and then use nitrogen-reducing bacteria such as luminescent bacteria, nitrifying bacteria and denitrifying bacteria. The dosage of anti-stress products and hard shell products is doubled, and the nitrite is high in the later stage, which is easy to cause attempted shelling and soft shell, and the amount of detoxification is doubled.
