The occurrence and prevalence of aquaculture diseases are closely related to the living environment of the cultured objects, the breeding of pathogens, and the organism's own resistance. To carry out prevention and control of aquatic disease, we must also take technical measures in improving the breeding environment, eliminating pathogens, and enhancing the immunity of the cultured animals. Improve the breeding environment for ecological control Control the spread of pathogens for biological control Application of Microecological Principles for Disease Prevention and Control Elimination of predatory organisms Protection of predators in aquaculture of farmed animals, including ferocious fish, aquatic insects, amphibians, reptiles and birds. The elimination of these enemy pests should take the following technical measures respectively. Applying growth substances to improve physiological function Conduct drug control and rational drug use

1. Improve water quality. Dilution of harmful metabolites in the culture ponds by injecting fresh water to improve the water quality and enhance the disease resistance of the cultured animals; or to inject other water sources to improve the ecological environment, such as injecting manure water to promote the growth of plankton. Through clear ponds, not only can wild fish be removed, game-eating organisms can be eliminated, but also pathogens can be killed and water quality can be effectively improved.
2. Adjust the temperature. The optimum temperature for many pathogenic parasites is around 20°C. By adjusting the water temperature, not only can the growth of pathogens be inhibited, but also the metabolism of the cultured animals can be accelerated.
3. Reduce stress response. For example, excessive changes in water temperature, severe deterioration of sediment, deterioration of feed, sudden rain, pH change, fishing harassment, noise interference, improper application of pesticides, etc., can all lead to stress response in farmed animals. The stress response will cause the energy consumption of the cultured objects to reduce the body's resistance, creating opportunities for bacterial and viral infections, and even outbreaks of disease.
4. Conduct ecological control. Ecological control aims to use the mechanism of mutual restraint between organisms to control pathogens, maintain the balance of aquaculture environment, and enable aquaculture to proceed normally. We can add beneficial organisms, such as photosynthetic bacteria, in the culture ponds to promote the conversion of harmful substances in the ponds; and put food-eating species in order to prey on diseased and weak bodies in the cultured objects.
1. Establish a quarantine system. In the process of introducing famous, special, excellent and new varieties, introduction and transplantation can also become a disease transmission channel. If the virus is infected, there is usually a period of incubation. As long as efficient and rapid detection techniques can be established, timely detection and diagnosis can be made.
2. Conduct ecological environment control. In aquaculture waters, there are not only a large number of pathogenic microorganisms, but also a large number of non-pathogenic microorganisms. The former is the pathogenic factor, and the latter is often the necessary condition to maintain the ecological balance of the aquaculture waters. While a large number of drug inputs, although killing the pathogenic microorganisms, will also make non-pathogenic microorganisms beneficial to the ecological balance of the waters suppressed. Therefore, one of the most effective means to deal with aquaculture viruses is to strengthen the monitoring and management of the water environment.
3. Use disinfectant control. The disinfectants used in aquaculture are oxidant type and non-oxidant type. The killing ability of the former (such as oxidant, potassium permanganate, etc.) is greatly affected by water temperature, pH value, ammonia nitrogen concentration, suspended solids and other factors. In particular, the ability to inactivate the virus is poor; the latter (such as copper sulfate, formaldehyde, etc.) have poor antiviral efficacy and toxic side effects, and it is difficult to effectively prevent and control infectious diseases, especially the occurrence and prevalence of viral diseases.
4. Conduct biological control. For example, polyculture and intercropping of cultured objects can cause some pathogenic microorganisms to be killed or devoured by mixed cultured and intervened breeding objects.
1. The basic principles of microecology. When aquatic organisms are in a healthy state, there is a relatively stable microbial population in their internal and external environment. This microbiota can not only promote the growth of beneficial bacteria, but also inhibit the proliferation of harmful bacteria and form the first line of defense against pathogenic bacteria. Under normal conditions, aquatic animals, microorganisms and ecological environment constitute a kind of dynamic balance with relative stability.
2. Use antibiotic drugs with caution. The abuse of antibiotics has made the problem of pathogen resistance more and more serious, and the amount of pesticides has been increasing. For the treatment of fish diseases, antibacterial drugs that are specific to pathogenic bacteria should be used in a targeted manner, rather than blindly adopting broad-spectrum antibiotics that are capable of killing non-pathogenic bacteria so as not to harm the fish. Relatively balanced microbial flora in the body.
3. Administer microbial preparations. A predominant group of beneficial microorganisms can be established in the body or surface of the cultured object to suppress the proliferation of harmful microorganisms and enhance the resistance and immunity of the breeding object. For example, photosynthetic bacteria (PSB), which are widely used in aquaculture, can not only purify water, prevent diseases, but also promote the growth of fish. Another preparation made of beneficial microorganisms such as intestinal anaerobic bacteria is used for the reconstruction and adjustment of the fish's intestinal micro-ecological system, and has significant effects in maintaining microecological balance and promoting growth and development.
1. Control ferocious fish. The common ferocious fish are Umbilicus, Eel, Eel, Stingray, Scutellaria, and Mackerel. The main means of controlling ferocious fish are: before fish fry and fingerlings are stocked, the fierce fish in the waters are cleared and killed; before the breeding seed is put in, the fierce fish seed of other water systems is prevented from being brought into the aquaculture waters; The breeding conditions for ferocious fish are to spawn and spawn places, and the large-scale fish species should be put in place to increase the ability of the breeding objects to resist ferocious fish. Corresponding fishing tackle should be used to coffer the fierce fish.
2. Elimination of aquatic insects. Common pests include red-nirs, water-headed worms, field plover, leeches, pine algae and leeches, clams, swords, leeches, etc. These pests, some slaughtered and prey on fish eggs, fish fry, some large-scale breeding, consumption of oxygen and nutrients in the water, so that the fry grow slowly, and even cause death. In order to deal with these water pests, the whole pool is splashed with lime before stocking to destroy its predators. After the fry are stocked, they are killed for specific pests, copper sulphate and extermination.
3. Kill the predators that harm the breeding object. There are water fleas, water snakes, water mice, frogs and pelicans, water birds and so on. These amphibians, reptiles, and birds not only prey on farmed animals, but also are intermediate host and pathogen carriers of certain parasites, and are likely to cause the prevalence of certain diseases. Trap, hunting, etc. should be used to drive or kill.
1. Apply growth material. The physiologically controlled growth substances are applied to the body of the cultured animals to increase their physiological functions, regulate the metabolism of nucleic acids, inhibit the reproduction and spread of pathogens, and supplement the essential elements of their growth. For example, Wakame, which uses growing material, has a good effect in controlling rot, not only improving the yield and quality of the cultured objects, but also improving the harvesting period. The main mechanism is that through the physiological regulation of the growth substances, the carbon and nitrogen metabolism is strengthened, the nucleic acid and protein content in the cultured subjects is increased, and the growth is promoted.
2. Application of rare earths to prevent fish diseases. Appropriate concentration of rare earth can inhibit the growth and reproduction of pathogens, stimulate the appetite of fish, enhance the resistance of fish, and enhance the prevention and treatment of fish diseases. Especially for grass carp, such as red skin disease, enteritis and gill disease, there is a clear control effect.
3. Develop and use biologically active substances. Bioactive substances are extracted from plants and their main function is to regulate nerve conduction and enzyme balance in vivo to promote protein synthesis and growth and development in the body, improve immunity, eliminate free radicals, and increase resistance to mutations, bacteria and bacteria. Viruses and other effects.
1. The right medicine. The scientific use of fish medicine can not only prevent and treat fish diseases, but also has the effects of regulating metabolism, improving digestion and absorption, promoting reproductive growth, and improving feed and fertilizer effects. The right medicine, the first correct diagnosis. Only when the diagnosis is correct can the treatment be performed. Second, find out the cause. Identify the source of pathogens, cut off disease sources, improve aquaculture waters, and create a good treatment environment. Again, scientific selection of drugs. Choose medicines that are both low-toxic, harmless, and low-residue to the diseased and cultured environment, but also cost-effective and cost-effective.
2. Reasonably apply drugs. The following three types of administration are generally used: (1) Administration of mixed water. Dissolve the drug with water and dilute it to a medicated bath or Quanchiposa. (2) mixed baits. When feeding, one should emphasize that the bait is mixed evenly, and the second is that the additives in the drug and feed should be reasonable. (3) Injection. Generally used for immunization or pro-fish injection.
3. Improve efficacy. The problem of drug resistance of pathogenic organisms has aroused widespread attention in the aquaculture community and solved the problem of resistance to insect pests. First, rotation of drugs is used to cut off the formation of drug-resistant populations of pathogens. Second, the development of medicinal synergists is adopted. Match, improve drug dare.
