What is the reason why moss is rampant in breeding ponds? What are the prevention and treatment methods?

Many friends engaged in aquaculture are no strangers to moss. Common moss species in the culture pond are Spirogyra, Cladophora and Hydrodictyon. In order to arouse the attention of farmers to this problem, Xiaobian today will analyze why moss will be flooded? What harm will it bring to farming? And offer a few prevention suggestions!

1. Why is moss flooding

The reason why moss is produced in large quantities is mainly because the pond is not cleaned thoroughly after the previous cultivation work is completed, which makes the organic matter at the bottom accumulate and cause the substrate to deteriorate. And some farmers in order to save breeding costs in the early use of fertilizer fertilizer containing chicken manure, which is also the main reason for the pond moss flooding.

II. Harm of moss flooding

Generally speaking, it does not matter much if there is a small amount of moss in the water during the breeding process, but once the environment of the water body is too suitable for the growth of moss, the overflowed moss will continuously absorb nutrients from the water body during the process of reproduction and growth, resulting in the water body becoming thin. As a result, the transparency of the water becomes higher and when sunlight hits the pond, it causes an emergency for the culture in the pond, which in turn affects the growth of the culture.

III. Prevention and control of moss flooding

1. Salvage

When there is a large amount of moss in the culture pond, the most direct way is to directly salvage a part of the moss.

2, the use of high-quality fertilizer

Just said that one of the causes of moss flooding is because farmers use some inferior fertilizers to save costs and thus provide conditions for the growth of moss, so the use of high-quality fertilizers is very necessary.

3. Exposure cleaning

Ponds are thoroughly cleaned and exposed to sunlight. For aquaculture ponds, proper cleaning of the bottom is very important, which is also an important means of maintaining water quality stability.

4. Shading treatment

The method of shading is very effective. When a large number of moss die, sodium humate can be used to sprinkle the whole pool with about two kilograms of water after one mu is opened, and the dead moss is oxidized.

5. Fermented water culture algae

To introduce suitable algae species according to the pond conditions at this time, cultivate high-quality algae to suppress excessive moss and use high-quality lactic acid and spores as water.

Of course, Xiaobian does not recommend the use of chemicals such as sulfuric acid when dealing with flooding moss, because this is very harmful to the culture and can easily cause poisoning of the culture. Especially when the temperature rises, if the dosage of chemical agents is not controlled well in high temperature environment, the toxicity will increase and then cause the death of a larger area of livestock. Therefore, Xiaobian here suggests that you do not take too radical a method, steady treatment is a safe choice.
