2. By bypassing the water source containing moss, we can also prevent it from the source. If moss enters the fish pond, it is inconvenient to inject seeds into the fish pond according to the water source, or it is inconvenient for farmers to mix some moss in the middle when transplanting aquatic plants, which eventually leads to the spread of moss in all fish ponds. As long as moss is not allowed to enter the pond, its harm will be gone. If you do this, you must pay more attention to fish farmers, which will take a long time. Secondly, the water source should not flow through the moss-covered area. These are all things that need to be investigated in advance.
3. Sun exposure If there is moss in the fish pond before raising, it can still be prevented by sun exposure in the pond 15-30 days or so. When the blasting is over, the area covered with moss must be carefully removed, and all the residues should be removed from the pond, and then some sludge should be removed from the pond, because there may be residues in the sludge in this case. Moreover, in fish ponds with much silt, the moss will rise more luxuriantly, which is also the position that needs attention.
4. Drug control is the first choice for many fishermen, but the problem of drug residues has not been dealt with. Sodium thiosulfate and peach essence can be regarded as common drugs in treatment. The diluted medicine is scattered in places where there are many mosses, and it will be fine if it dies. When doing that, it means that it is inconvenient to remove dead moss, which is very easy to produce residue. Secondly, it is very likely that the killing was not thorough, which gave the moss a chance to start again.
