Types and usage of commonly used pond cleaning drugs
Medicine cleaning pond is the use of drugs to kill pathogens, parasites and all kinds of ferocious fish, wild miscellaneous fish and other enemy organisms that harm fish, shrimp and crab seedlings in the pond, so as to avoid affecting the normal growth and development of farmed species due to diseases, so as to improve the efficiency of culture. At present, there are many kinds of clearing pond drugs, but different kinds of drugs have different effects. The commonly used pond cleaning drugs are quicklime, bleach, tea cake, ammonia, Croton, Tangkening and so on. First, quicklime clears the pond with quicklime, that is, calcium oxide, and its clearing function is that quicklime reacts with water to produce calcium hydroxide.

6 Cautions for High Temperature Fishing
Production practice has proved that adult fish caught in high temperature season should be carried out at night or early morning (before dawn), when the temperature is relatively low, which is conducive to the preservation of fish. When fishing, attention should be paid to the following points: 1. If fishing with a net, preparations should be made during the day to clean up debris on the surface of the fishing pond that hinders the net. 2. If soft vinylon nets are used, the height of the nets should match the depth of the fish pond as much as possible. If nylon nets are used to catch adult fish in larger fish ponds on the water surface, the mesh should be about 8 cm.
