Fish disease prevention and treatment device and method for freshwater fishes in high-temperature season

Abstract

The present invention discloses a fish disease prevention and treatment device and method for freshwater fishes in a high-temperature season, and belongs to the field of breeding. The method comprisesthe following steps of changing water, wherein a water pumping device and a water injection device are used for changing the water once per 6-8 days, the water change depth of each time is 15-20 cm,and the water level is kept in 1-2 m; spraying quick lime and chlorine dioxide disinfection powder, wherein the whole pond is sprayed with 30-35 g of the quick lime in 1 m<3> of a water body once per7-10 days; applying a bacillus microecological preparation, wherein 15-20 g of the bacillus microecological preparation in 1 m<3> of the water body is directly added into the water per 8-10 days; splashing copper sulfate, wherein the whole pond is splashed with 1.5 g of the copper sulfate in 1 m<3> of the water body, oxygen and running water are added, and the oxygen is added by using an oxygenation device; and performing scientific feeding, wherein the fishes are fed with 20-30 g of fish feed in 1 m<3> of the water body per one day. The prevention and treatment effect is good, the preventionand treatment method is scientific and reasonable, the morbidity of the fishes in the high-temperature season is effectively reduced, and the economic benefits of the breeding industry are improved.

Description

technical field [0001] The invention relates to the field of aquaculture, and more specifically relates to a device and method for preventing and treating fish diseases in freshwater fish in high-temperature seasons. Background technique [0002] Freshwater fish: In a broad sense, it refers to fish that can live in fresh water with a salinity of three thousandths. There are about 26,000 known species of fish in the world, and more than 8,600 species of freshwater fish. There are nearly 3,000 species of fish in my country. , of which there are more than 1,000 species of freshwater fish. [0003] Summer is the golden period for the growth of farmed fish, and it is also the peak period for fish disease outbreaks. With the arrival of the high temperature season, the stress response of farmed fish will be intensified due to environmental changes, and the resistance will decline, which will easily lead to the occurrence and prevalence of diseases. There are some new changes in sea...

Problems solved by technology

[0003] Summer is the golden period for the growth of farmed fish, and it is also the peak period for fish disease outbreaks. With the arrival of the high temperature season, the stress response of farmed fish will be intensified due to environmental changes, and the resistance will decline, which will easily lead to the occurrence and prevalence of diseases. There are some new changes in seasonal freshwater fish diseases. The main reasons may include: the germplasm degradation of cultured species, the deterioration of the cultured water environment, the weak awareness of health management during the breeding process, and the evolution of pathogens. Without good prevention and control devices and methods, it will easily lead to a large number of freshwater fish outbreaks, and then the fish will die, which will bring losses to the aquaculture industry
