Cultivation method for preventing grass carp enteritis disease

Abstract

The invention discloses a cultivation method for preventing a grass carp enteritis disease. The cultivation method for preventing the grass carp enteritis disease comprises the following steps that firstly, a cultivation pond is managed, wherein a 70-80 degree angle is formed on the straight bottom face of the cultivation pond and the side face where a water outlet is located, a U-shaped groove with the diameter being 20-30 cm is deep excavated in the joint of the bottom face of the cultivation pond and the side face where the water outlet is located, a double-layer filter screen is arranged on a water inlet, and a herb medicine bag with the weight being 200-300 g is placed in the middle of the double-layer filter screen; secondly, mixed cultivation management is performed, wherein 6000-8000 aquatic plants are grown at the bottom of the cultivation pond, flowing water with the height being 1.8-2.2 m is injected into the pond 42-50 days after growth of the aquatic plants, 10000 to 20000 grass carp fry is bred in the pond, 5-10 kg of a composite anti-disease agent is sprayed in the pond every other 20-25 days, and grass carps are driven for 30-45 min every day with a fish driving device; and thirdly, diseased fish is managed. The cultivation method for the grass carps can enhance the immunity and disease resistance of the grass carps, and therefore the enteritis disease is effectively prevented and treated.

Description

[0001] 【Technical field】

[0002] The invention relates to the field of grass carp culture, in particular to a culture method for preventing enteritis of grass carp.

[0003] 【Background technique】

[0004] Grass carp is one of the main breeds in freshwater ponds. It has the advantages of fast growth and delicious meat. Grass carp is a herbivore and is an excellent species that many farmers like to breed. However, grass carp has many diseases and low survival rate, which is harmful to grass carp. The larger one, and the most common one, should be enteritis of grass carp. Enteritis is one of the third oldest diseases of grass carp, and it will cause huge economic losses to farmers every year.

[0005] The cause of grass carp enteritis is that individual farmers, especially new farmers, do not really understand and grasp the growth law of grass carp and the conditions of the pond itself, such as poor water injection conditions, shallow water level, too large or too small, Insuff...
