I. Avoid partial splashing of drugs
Only the whole pond evenly sprinkled, leaving no dead ends, so that the entire fish pond pond water at the same time to achieve the effective concentration of drug action, in order to kill the fish body external pathogens, otherwise it will be due to the splashing of drugs is not uniform, kill pathogens is not complete, resulting in the recurrence of old diseases, and increase the cost of medication.
Second, avoid splashing medicine at the downwind place
Splashing in the downwind is not conducive to the uniform spread of drugs to the whole pond, because the wind will make the drug concentrated in one place (corner), should start from the wind, and gradually to the downwind of the whole pond evenly sprinkled.
Third, avoid anoxia floating head when splashing drugs
Fish should never be splashed with drugs when lacking oxygen and floating head, otherwise it will cause the fish to be irritable and even die in large numbers.
Fourth, avoid in the low air pressure, cloudy fish continuous weather splash drug
Cloudy and rainy, low air pressure or sudden changes in temperature, sudden rainfall, will make the pool water hypoxia and cause sudden changes in water quality, this time you can not splash the drug, otherwise it will cause the fish floating head or even a large number of deaths. Pouring medicine should choose sunny days and cool weather.
Fifth, avoid splashing medicine in the early morning
Dissolved oxygen in the pond is lower in the early morning, if the early morning splashing drug is easy to cause fish hypoxia floating head. It is more suitable to splash fishing medicine in the evening.6time, because the side night air and water temperatures are lower, which reduces fish restlessness and physical exertion.
Six, avoid throwing bait before splashing drugs
Splashing drugs before feeding will affect the normal feeding of fish, and should generally be done after the fish have finished feeding.2-3Hourly splash.
VII. Avoid splashing undissolved drugs
Undissolved drug particles are often eaten by carp, crucian carp, pangolin and other fish and lead to fish poisoning and death. The drug must be sufficiently watered down and dissolved before it is evenly sprinkled into the pond.
Eight, avoid overdose medication
Use of drugs should be in accordance with the instructions for the use of drugs, calculate the pond area, water depth, the amount of drugs. Excessive use of drugs will often result in high drug residues and toxic fish deaths, in addition to contamination of the water environment.
IX. Avoid the use of expired medicine
The use of expired drugs often do not achieve the effect of disease prevention. Farmers usually can also check by visual inspection, such as to be effective quicklime is just out of the kiln into a lump into a ball, powdery not lumpy, has been lumpy is ineffective, copper sulfate is blue-green crystalline, rusty that is, is ineffective.
X. Avoid mixing drugs at will
Common drugs that cannot be mixed are: bleach and quicklime, copper sulfate and quicklime, trichlorfon and quicklime. If trichlorfon mixed with quicklime, can generate highly toxic dichlorvos. In addition to the right medicine, some species have allergic to a drug, even if the water in a little bit of medicine, can cause fish poisoning and death.
