fish ponds to have fishy smell, indicating that the water is relatively fertile and there is a lot of humus at the bottom of the water, which leads to the growth of a large number of microorganisms, resulting in fishy smell. The best way to get rid of the fishy smell is to clean the bottom of the fish pond regularly, and if there is a water inlet and outlet, it can also be drained regularly to improve the water quality. Or clean up the algae in the fish pond, which often has a fishy smell.
the fishy smell of fish ponds? 1. Dredging: Dredging is an indispensable step for fish farming in fish ponds. In the process of long-term fish farming, residual bait and feces will fall to the bottom of the fish pond, which will gradually become silt, thus making the water body fishy and threatening the health of the fish. Therefore, when not raising fish, it is necessary to clean up part of the silt at the bottom.
2. Change the water: It is troublesome to change the water in the fish pond. If there is a special water inlet and outlet system, part of the water can be discharged, and then the water can be diverted into the pond. In this way, new water can inhibit the growth of microorganisms, thus improving the water environment and reducing the fishy smell of fish ponds.
3. Algae removal: The growth and reproduction of algae will also produce fishy smell, and excessive reproduction will occupy too much space, affect the growth of fish, and even pollute the water body after algae dumping, resulting in the death of fish. Therefore, it is better to remove algae regularly. Algae can be salvaged or some algaecide can be used, but the dosage should be controlled.
