It can be used as a cleaning agent before prawn and crab seedlings are released, and it can also be used to remove harmful fish or kill ciliates and polycondensates during the cultivation process. At the same time, it can promote the molting of prawn and the growth of young prawn.
The product can be biodegraded by itself in water body, which is beneficial to environmental protection. Its advantages are: low dosage, good effect, harmless for human and animal, safe use, and it is a protective agent for crabs and shrimps cultivation.
When applied, dissolve the protective agent with water and sprinkle it evenly in the crab and shrimp pond along the wind. Keep the water surface stable 6 hours after application. When the water temperature is lower than 18 ℃, the water surface stable time can be appropriately prolonged. The product will degrade automatically 48 hours after application and lose its activity.
