    Application of chlorine dioxide in aquaculture

    Release date:2017-12-13 10-15-13

    Chlorine dioxide is a common disinfectant in the field of aquaculture and has been widely used in disease prevention and control in aquaculture.

    Chlorine dioxide disinfectant is safe, high-efficiency, low-toxic, no residue, green and environmentally friendly. It can effectively kill bacteria and viruses in water. It is commonly used for external disinfection of fish, shrimp, crab, turtle, frog and other cultured water bodies to prevent bacterial diseases. Agent.

    Chlorine dioxide is also a water quality improver that can kill algae and remove odor in water, improve water quality, generate oxygen, improve oxygen deficiency in the pool, and increase oxygen content in water.

    Chlorine dioxide is also a strong aerobic agent, which can oxidize harmful substances such as nitrite and hydrogen sulfide in water, so as to achieve the purpose of improving water quality.

    Fish pond chlorine dioxide disinfectant is used not only in clear ponds, but also in clear ponds when no aquatic products such as fish are cultured in water, and can be directly disinfected during the breeding process, not only for fish aquaculture. It causes harm and can effectively prevent various viral diseases of aquatic fish and make it grow healthier.

    Chlorine dioxide disinfectant has good control effects on infectious diseases caused by pathogenic microorganisms such as bacteria, fungi and viruses in fish, shrimp, crab, turtle and frog.

    [The role of chlorine dioxide in killing bacteria and viruses]

    1. Chlorine dioxide is a broad-spectrum disinfectant that has high levels of pathogenic microorganisms in water, including viruses, buds, heterotrophic bacteria, sulfates, reducing bacteria and fungi in water distribution networks. The killing effect.

    2. Chlorine dioxide can kill E. coli in a wide range of pH values. Chlorine dioxide diffuses faster in water than chlorine, so it is more effective than chlorine at low concentrations.

    3. The role of chlorine dioxide in killing viruses is more effective than ozone (O3) and chlorine. During the flood period, chlorine dioxide has a good killing effect on many viruses such as Coxsack (intestinal) bacteria, human enterovirus, herpes virus, Newcastle virus, phage, vaccinia virus and poliovirus. . If a chlorine dioxide dose of 0.02 mg/l is used, the virus can be killed in a few minutes, which is much more effective than chlorine. Low-dose chlorine dioxide also has a strong helminthicidal effect. If chlorine dioxide is used at 0.5 mg/L, the aquatic bifamily can be killed in the crustacean, while chlorine is used to kill 6.0~ 7.0 mg / liter.

    [The benefits of chlorine dioxide in aquaculture applications]

    1. Chlorine dioxide is easily soluble in water, and the disinfection effect is not affected by the pH of the water.

    2. Chlorine dioxide can effectively kill bacteria, viruses, fungi, bacterial spores and phage in water. In water, due to the adsorption between the active ingredient molecules of chlorine dioxide and the capsid protein of the virus, a high concentration of chlorine dioxide molecules is accumulated on the surface of the virus particles, thereby enhancing its killing effect. Chlorine dioxide can perform good sterilization in the range of pH 6-10. In water with pH 8.5, the sterilization speed is more than 20 times faster than chlorine. The greenhouse water often contains ammonia, and the use of chlorine dioxide neutralizes ammonia to reduce the disinfection effect. Therefore, it can compensate for the weakness that ozone disinfection cannot remove ammonia.

    3. The bactericidal ability of chlorine dioxide is stronger than that of chlorine, the bactericidal effect is faster than that of chlorine, the bactericidal effect is more than 10 times that of chlorine, and the duration of the remaining dose is longer. Practice has shown that killing almost 100% of the microorganisms with a dose of 2.0 mg/L for 30 minutes, while the remaining chlorine dioxide concentration is still 0.9 mg/L. During the application process, substances such as organic chlorine and other toxic side effects are not produced, so there is no stimulating effect on fish and shrimp, and the fish and shrimp feeding and normal development are not affected. It does not damage plankton, can improve water quality, deodorizes and preserves, and is a true green disinfectant.

    [Application range of chlorine dioxide in aquaculture]

        Fish: bacterial sepsis, liver disease, red skin, rotten sputum, rotten tail, enteritis, white skin, printing, water mold, vertical scales, hemorrhoids and other diseases;

        Crabs: rotten phlegm, edema, rotten shell, enteritis, trembling, landing problems, etc.;

        Shrimp: fulminant epidemic shrimp disease, red legs, rotten eyes, brown spots, white spots, rotten sputum, fluorescent disease, red stomach disease, fungal diseases;

        Soft-shelled turtle: scleroderma, red, white floor disease, hemorrhagic disease, perforation, etc.;

        Frogs: diseases such as skin diseases and eye diseases.

    [Usage and dosage of chlorine dioxide disinfectant in aquaculture]

        1. Disinfection of fish ponds, improvement of water quality with a concentration of 0.3mg/L chlorine dioxide in the whole pool, chemical oxygen demand has a significant decline (7.7% ~ 9.5%), dissolved oxygen has a significant increase (10.7% ~ 12.2%).

        2. The killing of algae is splashed with a chlorine dioxide concentration of 2 mg/L. The algae die within 10 days and are harmless to fish. Sprinkling the whole pool with chlorine dioxide at a concentration of 0.5 mg/L can inhibit algae reproduction.

        3. Sprinkle the whole pool with chlorine dioxide at a concentration of 0.1-0.2ml/L for 2 times. At the same time, taking antibacterial drugs orally can prevent some common fish diseases.

    [Chlorine dioxide for the preservation of aquatic products]

        After the capture, the fish and shrimp, due to the amino acid enzymes in the body, the blackheads, abdomen and tail limbs become black after 48 hours, and the shrimp body begins to deteriorate. 50 ppm of stabilized chlorine dioxide can be used to soak the newly caught shrimp body. After 20 minutes, the ice cubes with 20ppm stabilized chlorine dioxide can be used for fresh preservation, which can achieve satisfactory fresh-keeping effect, and can keep the original color, aroma and taste of the shrimp unchanged during the storage period of 7-10 days.
