Control methods of moss in fish ponds

For the water from the fish pond, moss is very easy to appear, but the moss has a great influence on the fish pond. More moss will affect the water quality of fish ponds and the fattening effect of fish. After moss dies in fish ponds, the water quality will become worse, and some toxins will be decomposed, leading to a variety of fish diseases. Let's learn about the treatment of moss in fish ponds.

1. Water control

Water control is one of the ways to control moss. Unlike other aquatic algae, moss is very easy to survive in shallow water, which allows moss to receive more sunlight, so pond moss in shallow water is generally very exuberant. Therefore, when there is moss, it is best to avoid the existence of shallow water. If the fish pond is not convenient to change, you can build a certain amount of sunshade net in the moss growing area to inhibit the growth of moss, and then slowly reduce the shallow water area.

2. Avoid water sources containing moss

We can also prevent and cure the moss from the root. In order to enter the fish pond, the moss either flows the seeds into the fish pond through the water source, or some moss is mixed with some moss when the fish farmers transplant the water grass, which eventually causes it to spread throughout the fish pond. As long as the moss is prevented from entering the pond, its harm will not exist. To do so, fish farmers need to pay more attention to it, which takes a lot of effort, and secondly, water cannot flow through areas with moss, all of which have to be inspected in advance.

3. Exposure to the sun

If there is moss in the fish pond before it starts breeding, then draining the water and exposing the pond to the sun for about 15-30 days can also achieve the control effect. When the sun exposure is over, you need to clean up the mossy area carefully, remove all the residue out of the pond, and then clean up some of the silt in the pond, because there may also be residue in the silt at this time. And muddy fish ponds, moss growth will be more exuberant, this is the place that needs to pay attention to.

4. Drug prevention and treatment

Drug treatment is the first choice for many fish farmers, but the problem of drug residues has not been solved. Copper sulfate, moss net and other drugs are more common for treatment. After diluting the proportion, sprinkle the medicine on the exuberant area where the green moss grows, and then wait for it to die. When doing so, it means that it is not convenient to clean up the dead moss, which is easy to form residues, and secondly, it may not be killed thoroughly, which will give the moss a chance to make a comeback.

These are some of the treatments for moss in fish ponds, each of which has its own advantages. Some friends may also have some local methods to treat moss, which can be shared if they are effective. Choose these methods or according to the actual situation of the fish pond, which is convenient to use.
