Before stocking the shrimp, all predatory, competitive, destructive and pathogenic organisms that are not conducive to the survival of the shrimp must be removed. Before clearing the pool, filter nets should be installed to avoid the entrance of harmful organisms into the pool from the gaps in the gate after medication. Clearing time is usually selected on sunny mornings in order to improve the effect of pesticide application.
The method of clearing the pool is to drain the pool water as much as possible after harvesting the shrimp, killing most of the predator creatures through the months of exposure and dryness before the winter; the second is a pool of ponds with accumulated water, which can be used in shrimp ponds. About 10 days before fertilizing and breeding basic food organisms, according to the status of the enemy's harmful organisms, select the appropriate drugs for clearing the pond.
However, it should be noted that it should be applied in the wind, and the wind can be used evenly. After the drug is applied, it should be constantly stirred to evenly mix the water and the drug. Pay attention to the dead pool of shrimp pond, water edge, potholes, and crabs. After clearing the pond, it is necessary to comprehensively check the efficacy. If the fish is still found after a day, add the medicine and clear it again. Pay attention to medication safety, do not contact with human skin when using, used instruments should be cleaned in time.
