Is it affected by the weather to disinfect the crab pond with iodine?

1, disinfection of crab ponds with iodine is not affected by the weather.

2. After a long period of continuous rainy weather, the balance of various factors in pond water was generally broken, especially when the microecological balance was broken, the water quality changed greatly, the beneficial bacteria decreased sharply and the harmful bacteria increased greatly. If proper disinfection measures are not taken, fish and shrimp will soon get sick. At this time, due to the weak constitution of fish and shrimp, the dissolved oxygen in water is also low, and the use of some drugs will also consume the dissolved oxygen in water. Therefore, when using disinfectants, we should choose drugs that are less irritating to fish and shrimp, such as povidone iodine and dibromohydantoin. At the same time, attention should be paid to keeping the water body in a state of high dissolved oxygen, and disinfectants should be used in conjunction with oxygenators when necessary.

3. Before the rainy season or rainstorm, the whole pond should be sprinkled with water antidotes and water degradants to detoxify the water, increase the oxygen permeability of the water, create a more comfortable environment for fish and shrimp as much as possible, and then sprinkle with anti-stress drugs such as Vc and glucose to enhance the anti-stress ability of prawns. In case of continuous rainfall for too long, anti-stress drugs can be sprinkled when the weather is good halfway.
