The problem of parasites in aquaculture has always been a headache. Often it is just killed today, and it breaks out again a few days later. We need to know one thing, parasites are not clean.
Why are parasites getting harder to kill now?
1. Drug resistance. When insecticides are used to kill insects, parasites that have not been killed develop resistance, survive, and their reproducing offspring are also resistant.
2. Self-protection mechanism. Usually with chemical drugs, many parasites instinctively develop self-protection, producing a large number of eggs and offspring.
3. Changes in the ecological environment. When the number of phytoplankton in the water body is relatively balanced, parasites will not break out, and the use of chemical agents will break the ecological environment.
How to avoid parasite outbreaks?
1. Clear the pond thoroughly
Avoid parasite outbreaks by improving the pond environment.
2. Improve the physique of fish
Improve the physical fitness of fish, enhance the immunity of fish, and avoid the decline of fish immunity caused by lack of oxygen and excessive feeding.
3. Prevention and control work should be done well
"Prevention is greater than cure". With the increase of breeding density, the water environment is becoming more and more harsh, the disease is becoming more and more complex, the parasite resistance is getting stronger and stronger, and the insecticide effect is getting smaller and smaller.
Comprehensive insect control
Regular mixtures are filled with eucalyptus essential oil, multivitamin and eucommia leaf extracts to strengthen the physique of fish and prevent and control parasites.
