Aquaculture method capable of preventing red skin disease of grass carp

Abstract

The invention discloses an aquaculture method capable of preventing a red skin disease of a grass carp. The aquaculture method comprises the following steps: (1) improving soil, namely smashing a soil block at the bottom of an aquaculture pond, soaking with water for 15-20 days, then planting ciliate desert-grass for 2-3 years on soil in the specification of 40*60cm, removing the ciliate desert-grass, and then solarizing the aquaculture pond for 15-20 days; (2) carrying out polyculture management; and (3) carrying out diseased fish management, namely soaking a diseased fish for 10-15 minutes with a biological disinfectant, rinsing thoroughly, then putting into an isolation pond added with a disease-resistant agent, carrying out isolated aquaculture, and continuous culturing in the aquaculture pond after the diseased fish is healed for 2-3 days. The aquaculture method disclosed by the invention not only can efficiently prevent and treat the red skin disease of the grass carp but also can obviously reduce content of heavy metals in the soil, and the technique has obvious guiding significance on large-scale and industrialization development of the grass carp.

Description

【Technical field】 [0001] The invention relates to the cultivation field of grass carp, in particular to a cultivation method for preventing red skin disease of grass carp. 【Background technique】 [0002] 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 red skin disease of grass carp, which causes grass carp to bleed and become inflamed, and scales to fall off. Red skin disease is one of the third oldest diseases of grass carp, and it causes huge economic losses to farmers every year. [0003] The symptoms of red skin disease are: sick fish move slowly, unresponsive, weak and swim alone on the water surface, local or large-scale hemorrhage and inflammation on the body surface, and sca...

Problems solved by technology

[0004] The current main method for the prevention and treatment of grass carp red skin disease is to sprinkle chemical substances into the water, and take the method of eliminating bacteria in the water to prevent and control grass carp red skin disease. Therefore, the amount of chemical substances is too much, and it is easy to have too many chemical substances in the grass carp body. It affects the health of people who eat it, and due to the random discharge of chemical sewage and domestic wastewater in the existing soil, many soils are polluted by heavy metals, and once fish are cultivated in soil contaminated by heavy metals, it will not only easily reduce the disease resistance of fish It may also transfer heavy metals to the body of the consumer through the food chain, causing serious damage to the body of the consumer
