Advantages and disadvantages of compound iodine in aquaculture?

At present, the scale and intensification of aquaculture are increasing, and the stocking density of cultured animals is increasing, which leads to the increasing frequency of disease outbreaks in cultured animals. Compound iodine is mainly used as disinfectant in aquaculture, which has strong disinfection ability and certain bactericidal effect, and can inhibit harmful bacteria such as viruses, molds, protozoa and spores. Compound iodine can also be used to soak fish eggs and disinfect utensils.

First, the role of compound iodine in aquaculture

1, compound iodine is a good soaking disinfectant, mainly used as disinfectant. Compound iodine can soak fish eggs and disinfect utensils, and can be used in many cases, because the iodine contained in compound iodine has strong activity and can inhibit and kill bacteria, viruses, molds, protozoa, spores, spores and nematodes.

2. Compound iodine can also be used for scaleless fish. Because scaleless fish are very sensitive to many disinfectants, such as Jiang Tuan and channel catfish, we should use milder drugs.

3. Compound iodine can also be used to treat bacterial or viral diseases. In this respect, compound iodine has a very unique curative effect, such as some stubborn rotten cheeks. As long as you insist on using compound iodine for half a month, it will be well controlled. However, when using, it is necessary to pay attention to the concentration of iodine below 50ppm, otherwise it will be toxic to fish, and the disinfection water after cleaning utensils should also be avoided from being directly poured into the culture pond.

2. What are the advantages and disadvantages of compound iodine?

1, advantages

(1) compound iodine has a good bactericidal effect, is easily soluble in water, does not remove iodine, and has a relatively stable performance, and does not irritate skin and mucous membranes at a low effective concentration.

(2) Compound iodine can be safely used for preventing and treating bacterial diseases and viral diseases of aquatic organisms, and has no irritation, and can be used for medicinal bath disinfection of fish eggs and immersion bath of fry.

2. Deficiencies

(1) compound iodine can't kill some stubborn bacteria, such as spores, because these compound iodine has little effect on these bacteria, and compound iodine is also sensitive to light and easily disturbed by organic matter.

(2) Compound iodine should not be used in cold-water fish and other fish sensitive to iodine, otherwise improper use may lead to a large number of fish deaths. When using it, attention should be paid to checking whether fish are allergic to compound iodine.
