Shrimp culture in canvas ponds is difficult to discharge pollutants and needs manual operation. The specific method is similar to changing water. Pump or siphon the water from the bottom, and suck it out together with the residual bait and feces. Compared with the conventional earth pond, the biggest problem of canvas pond is that it can't decompose organic matter, so the cleaning of dirt is particularly critical, otherwise it will pollute the water quality and kill a lot of shrimps. First, how to pollute the shrimp in the canvas pond The shrimp in the canvas pond is difficult to pollute and needs manual operation. The specific method is similar to changing water.

If you want to use a bigger one, you must pay attention to the fixation of steel pipes and other structures, otherwise there will still be the risk of falling apart.

2. Oxygen-increasing equipment: Shrimp has a great demand for oxygen, so it is necessary to install oxygen-increasing equipment in the canvas pond to ensure that the dissolved oxygen in the water is sufficient and there is enough light for aquatic plants to release oxygen through photosynthesis.

3. Provide shelter: In order to avoid the shrimp being killed, it is necessary to provide some shelter in the pond, because this kind of animal will shell and grow regularly, and it will be fragile after shelling and may become the same kind of food. With asylum, the survival rate can be improved.
