The fishy smell of fish farming mainly comes from the residual bait and fish feces in the water, which will produce some odor after decomposition.The best way to remove it is to strengthen filtration, which not only sucks the dirt into the filter tank, but also decomposes it by microorganisms, and the ammonia nitrogen produced can be converted by nitrifying bacteria, so that there will be no odor.
Fish farming must change water, long-term non-changing water will also lead to water quality aging, so it will be easy to have a fishy smell.Usually do not change water too often, frequent water change is easy to stimulate the fish, which is harmful to its health.Usually once a week can be changed, if the filter system is better, you can change half a month.
If the fish is sick, there may also be some fishy smell. In view of this situation, it is best to isolate and raise the sick fish to prevent the disease from spreading to the healthy fish.Then we should change the water to reduce the content of harmful substances in the water, at the same time, we should raise the water temperature, enhance its resistance, and properly salt, in order to prevent pathogens from invading the fish.
If there are aquatic plants in the fish tank, the aquatic plants will rot after death and emit a fishy smell.Therefore, regular inspection should be carried out, and if there are rotten aquatic plants, they need to be fished out in time to avoid polluting the water body.In addition, dead fish will also produce a fishy smell, so be sure to fish out and clean up.
