How to prevent high temperature in river fish fry breeding diseases

Author:Xinxing Aquatic Products Processing Factory Click: Time:2019-12-11 17:58:07

With the arrival of the high temperature period, diseases frequently occur in the aquaculture process, causing great economic losses to aquaculture farmers. Because once the crabs become ill, they will reduce or even stop feeding, so even the best medicine bait can hardly achieve the desired effect, which will cause some losses. Therefore, the disease of river crabs should be prevention-oriented, so that early detection and early treatment can be achieved without disease first. Through regular disinfection of water bodies, oral administration of antibiotic baits, scientific feeding, regular use of microbial preparations and substrate modifiers and other measures, the effect of preventing crab disease outbreaks has been achieved.

 

Aquaculture knows that the occurrence of disease is caused by the joint action of the host, the breeding environment and pathogenic microorganisms. Only when the water quality deteriorates, the pathogenic microorganisms reach a certain concentration, and the crab's immunity due to stress will cause the disease to occur. Then we can do a good job in disease prevention and control from these three aspects: First, keep water quality stable. Keep the water fresh and stable. In fact, the water quality in the pond does not have to be adjusted to the best, but it must be stable and have a certain buffering capacity. When the external environment changes, the water body can also remain relatively stable, which can reduce the long-term stress of the river crab caused by the fluctuation of the water environment. And consume too much energy, so when we check the water quality indicators such as ammonia nitrogen and nitrite in the water quality are slightly below the standard, we do not have to rush to adjust and deal with it, keep this state all the time, the river crab will slowly adapt. , This is more conducive to the growth of river crabs. Therefore, regularly use the substrate modifier to decompose the organic matter at the bottom of the pool and reduce the accumulation of harmful substances. 5-7 days is a cycle, using microorganisms such as Bacillus and Lactobacillus regularly to improve water quality, ensure the dynamic balance of algae and bacterial phase of the water body, maintain the stability of the water body, reduce the stress of the river crab and cause immunity decline.

 

Keep the water quality stable: biological water purification treasure (3-8 acres / bottle) + enzyme Lishengbao (3-6 acres / bag), 5-7 days / cycle, a small number of times.

 

Second, reduce the accumulation of pathogens. A large number of pathogenic microorganisms have always been present in the water body. As the water temperature rises, a large amount of bait residues and feces accumulate, providing the pathogenic microorganisms with the nutrients needed for reproduction, causing a large number of pathogenic microorganisms to grow, and accumulating to a certain concentration in the water body. It will cause disease outbreaks. Regular disinfection during the breeding process can not eliminate all pathogenic microorganisms in the water body. It only inhibits the growth of pathogenic microorganisms and reduces their concentration on a regular basis to reduce the occurrence of diseases, so we need to use them regularly Povidone iodine and other drugs, disinfection to improve the water environment.

Package: Shuangshuibao (2 acres / bottle) + Iodine (2 acres / bottle), the water temperature is low in the early stage of breeding (3-5 months), and the growth rate of microorganisms is slow, 10-15 days / cycle; (September-September) The water temperature is high, and the growth rate of microorganisms is fast, 7-10 days / cycle.

 

Third, improve crab immunity. Improving the crab's immunity is based on the crab's own body, which has the ability to resist pathogens from the inside out, enhance its disease resistance, and reduce the incidence of disease. A very common phenomenon in the breeding process: the same water environment, the same climate, the same management level, why do some crabs develop disease and die, while others can grow healthy? Essentially, it is determined by the body's autoimmunity. River crabs have strong immunity but less disease, and weak immunity have more disease. Then we can feed high-quality bait to ensure adequate nutrition of the crabs and promote the healthy development of immune and digestive organs, especially the healthy development of the liver and pancreas. During the peak feeding period, regularly mix and feed some drugs that protect the liver and intestines to reduce the liver and pancreas of the crabs. Burden, improve immunity, high incidence of disease (July-August), mixed with antifungal drugs such as flufenicol, from the two aspects of adequate nutrition and healthy growth and development of liver and pancreas, improve the crab's autoimmunity.
