Traditional aquatic disease prevention and control technology

For the problem of bleeding and surface rot caused by parasites in fish, my personal suggestion is to raise the water in the pond first if western medicine is not used. After the water quality is good, parasites can be suppressed to some extent. After disinfection, change the water for a day or two before killing insects. Some broad-spectrum insecticides, such as abamectin, can be used to kill insects. This medicine can kill rotifers, giant salamanders and so on. Sporozoa has a high water temperature, which can kill insects when the water temperature reaches 20℃, and trichlorfon can kill insects.

Junlike purges fire and detoxifies, which is mainly used for the prevention and treatment of bacterial and viral diseases of fish. This product is a compound preparation, which adopts the essence extracted from plants, has strong permeability, can penetrate the blood-brain barrier and reproductive barrier, and has strong antibacterial property. It is a specially cultured product. Reservoir culture: Reservoir is the place where local residents get domestic water resources. It is forbidden to breed in reservoirs now, because feeding and water transfer will pollute the water quality.

In recent years, eucalyptus essential oil has been used for control. The pure natural extract of eucalyptus essential oil can penetrate the biofilm structure of bacteria and parasites, destroy the integrity of cells, and make the dysfunction of bacteria and insects play a role in expelling worms and inhibiting bacteria. To strengthen water quality management and make the water quality stable, it is best to use light green water to raise fish fry, because this water body has great buffering power to the environment and little change in water quality, which is beneficial to the growth of fish and has a certain inhibitory effect on rotifers.

For fish culture water, if there is insufficient oxygen in the water, sometimes the fish in the pond may not float, but it will affect the growth and water quality of the fish and be more dangerous. Prevent it by hanging a bag with medicine. This method has a certain preventive and therapeutic effect on early symptoms and fish disease season. The medicine for hanging bags can be crystal trichlorfon and can be hung around the food table. In short, we must do a good job in early prevention, nip pests in the cradle, stop being a fireman fighting fires everywhere, and at the same time, don't forget to enhance the immunity of fish.
