Problems solved by technology

[0003] At present, silver carp printing disease is treated with antibiotics such as norfloxacin, ofloxacin, streptomycin sulfate and tetracycline, which can make the bacteria resistant to drugs, making it more and more difficult to control, and it will also cause antibiotic residues in the fish. Harmful to human health

Embodiment 1

[0017] A method for preventing and treating silver carp printing disease, comprising the following steps:

[0018] (1) Breeding management: When the body length of fry reaches 4-6cm, male and female silver carp are cultured separately, and male and female silver carp are divided into fry, adult fish and broodstock according to age, and cultured in separate ponds. The vitality of each group of silver carp is equivalent , to reduce the damage between individuals, the inner wall and bottom of the fish pond are covered with foam material, which is safe and non-toxic, increases the brightness of the water body, promotes the growth and development of silver carp, enhances disease resistance, reduces skin damage of silver carp, and avoids pathogenic bacteria infection, every 2 days Sprinkle disinfectant into each fish pond, the amount of spraying is 1.1g / m 3 , enhance resistance, inhibit the growth of pathogenic bacteria;

[0019] (2) Feed management: During the silver carp breeding...

Abstract

The invention mainly relates to the technical field of culturing and discloses a prevention method for chub stigmatosis. The method comprises steps of culturing management, forage management and water body disinfection. The method is simple and effective. Morbidity of the stigmatosis can be reduced by 2%, growth period can be advanced by 40 to 50 days and culturing income can be improved by 14.3%. Chubs are separately cultured according to sexuality and ages, so pollution to the whole water area by germs can be avoided, germ infection can be prevented and culturing loss can be reduced; pure phytoextracted-sanitizer is applied for regular disinfection, so nutrients and health-caring components can be provided and resistance can be enhanced and bacteria and insects can be prevented and killed; production of water body pathogenic microorganism can be prevented; artificial feed is only fed during the chub culturing process, so balanced nutrients can be achieved and proper taste can be provided; chub food ration can be increased, so growth can be accelerated; water cleanness can be maintained; occurrence of the stigmatosis and other diseases can be reduced; a pond can be regularly cleaned; crud salt is added for disinfection; pool pH values cannot be affected; and the method requires low cost and can be repeatedly used, so culturing cost can be reduced.

Description

technical field [0001] The invention mainly relates to the field of breeding technology, in particular to a method for preventing and curing silver carp printing disease. Background technique [0002] Silver carp printing disease can occur all year round, but it is more prone to occur in summer and autumn, and the peak period is 28-32 °C, and the infection rate of silver carp and silver carp can be as high as 80%. Symptoms are mainly round or oval erythema on both sides of the anus or the base of the caudal fin and the underlying muscles of the diseased fish. The surrounding area is congested and red, resembling a red mark. In severe cases, the scales fall off and the muscles rot until the bones and internal organs are exposed. eventually to exhaustion and death. [0003] At present, silver carp printing disease is treated with antibiotics such as norfloxacin, ofloxacin, streptomycin sulfate and tetracycline, which can make the bacteria resistant to drugs, making it more an...
