If the bottom of the fish pond is black, it means that the substrate is not good. You can dig out the silt when you clean the pond, or drain the water in the pond when you are not raising fish, and then expose it to the sun for a few days. In this way, the soil will be loosened and the harmful substances inside will be released. If it is winter, you can use snow to freeze the fish pond, which can also eliminate some pathogens, parasites and other harmful substances.

1. how to deal

with the blackening of the bottom of the fish pond? The blackening of the bottom of the fish pond indicates that the substrate is not good. You can dig out the silt inside when cleaning the pond, or drain the water in the pond when not raising fish, and then expose it to the sun for a few days. In this way, the soil will be loosened and the harmful substances inside will be released. If it is winter, you can use snow to freeze the fish pond, which can also eliminate some pathogens, parasites and other harmful substances.

2. Why is the bottom of the fish pond blackened

? 1. The pond is not thoroughly cleaned: The reason why the bottom of the fish pond is blackened is that the pond is not thoroughly cleaned. Before fish farming, the pond must be cleaned. Every winter, the pond should also be cleaned. The pond should not only be disinfected with quicklime, but also the silt at the bottom should be treated. It should not be too thick, otherwise it will affect the water quality and cause the bottom of the pond to turn black.

2. Feeding too much: In the daily process of fish farming, do not feed too much bait, and do not feed too fast, which will cause the fish to eat too much or too late to eat, resulting in a large number of residual bait, residual bait accumulated at the bottom of the water, so that the bottom of the pond is black. Therefore, controlling feeding can improve the blackening of the bottom of the pool from the source.

3. High stocking density: If there are too many fish and the stocking density is relatively high, the excrement of the fish will be too much, which will also cause the bottom of the pond to turn black. Fish farming must control the density, do not blindly pursue the expansion of income, raise too many fish, so once there is a problem, the loss is huge.
