More wonderful, please click the blue words above to follow us! In April, the temperature rises rapidly. With the increase of cultivation time, the food residues and feces are deposited at the bottom of the pond. With the aging of water plants that are not resistant to high temperature, many environmental changes will cause a common result - the outbreak of Vibrio! When the amount of Vibrio reaches a certain level, it will cause the disease of crawfish.
Vibrio is a kind of conditional pathogen. Crawfish with strong immunity will not be infected generally. Those with weak constitution will be infected generally. After being infected with Vibrio, crayfish's general vitality will become poor, vulnerable to external environment stress, intestinal inflammation, slow growth, unable to normal shelling, and eventually lead to death.
There are three main causes of crayfish death caused by Vibrio
1. After Vibrio infection, it will continue to breed in crawfish and release toxins until crawfish die.
2. After infected with Vibrio, the food will be poor, and the body will be poor, which is easy to cause other diseases, and eventually lead to the death of crawfish.
3. The crayfish with poor constitution infected by Vibrio are infected in the pond. At the same time, the crayfish that died will be infected twice by other healthy food intake, which will lead to more crayfish death.
The treatment effect of Vibrio infection is relatively poor, because there is no good way to deal with the outbreak in time, the number of crawfish dying will be more and more day by day, and the effect of medication is relatively poor. It is difficult to treat vibriosis. Are we at a loss? Of course not. Vibriosis is a conditional pathogen. Generally speaking, it will not cause disease. Therefore, we have done a good job in prevention and control measures, or we can control the occurrence of vibriosis!
So how to do it?
1. First of all, to protect the physical health of crawfish and improve the immunity of crawfish. Bile acid and eucommia leaves extract were added to the feed. Bile acid can promote the digestion and absorption of nutrients in feed, detoxify the liver, and enhance their own physique and immunity; Eucommia leaves extract can inhibit the reproduction of harmful bacteria, protect the intestinal tract, and resist the invasion of Vibrio.
2. Increase the number of photosynthetic bacteria and Bacillus in water, and inhibit the growth of Vibrio through competitive nutrition and living environment.
3. Use Eucalyptus Lechang essential oil to prevent and control Vibrio. Eucalyptus Lechang essential oil is rich in 1,8-cineole, monoterpene, sesquiterpene and other natural active ingredients. It has a natural anti-bacterial and anti-inflammatory effect, and has an obvious inhibitory effect on Vibrio. It can inhibit Vibrio in vivo by taking it internally and inhibit Vibrio in water by splashing it externally. It is safe and nontoxic, and does not damage water body or shrimp body.
Vibriosis is a disease caused by environment. As long as the prevention work is in place, it is easy to avoid the outbreak of the disease. Therefore, in the process of breeding, we must ensure the health of water body and the good constitution of crawfish, and use safe drugs to prevent and control, to avoid the occurrence of diseases.
