Summer is the period of high incidence of fish disease, and it is also the peak period for the use of fishery medicine. The following points should attract everyone's attention:

1. When two kinds of drugs are mixed, they should be dissolved in water and then mixed. Copper sulfate, ferrous sulfate and potassium permanganate should all be dissolved in buckets or pots with water. Bleach, trichlorfon and other powder drugs, should first be adjusted into paste with a small amount of water, and then diluted with water, so as not to be caked and eaten by fish. The following drugs should not be mixed: bleach and quicklime, copper sulfate and quicklime, trichlorfon and quicklime.

Second, the time for the administration of drugs should generally be arranged at about 4: 00 p.m. Do not splash medicine in the early morning to avoid anoxic floating head of fish, and do not use medicine in direct sunlight at noon, so as not to cause production accidents.

Third, when using copper sulfate, we should pay attention to: 1. The calculation of the amount of copper sulfate should be accurate; 2. The temperature of the water used to dissolve copper sulfate should not exceed 60 ℃, otherwise it will invalidate copper sulfate. Copper sulfate should not be used so as not to endanger human health.

Fourth, sprinkle liquid, can use sprayer, can also use wooden ladle or spoon to sprinkle the whole pond evenly, must not be dumped at a fixed point.

Fifth, make a careful diagnosis and prescribe the right medicine to avoid waste and increase the cost.

Sixth, when the water temperature is high, the effect of spraying medicine is the best, and the spraying should be uniform. Insoluble drugs should be fully dissolved in water before sprinkling, so as not to leave particles to poison the fish.

7. People should not leave the pond within 1 ~ 2 hours after the use of fish medicine. once a serious floating head or dead fish is found, new water should be injected quickly.

8. Fish should not take medicine at the time of floating head or at the end of floating head, otherwise a large number of fish will die.

9. The medicine should be sprinkled gradually from the upwind to the downwind, not against the wind.
