Catfish cannot be thoroughly cleaned because it is secreted by the skin. Put the live fish in a pot (without water), sprinkle with salt and let them wipe the mucus off each other. When slaughtering, clean gills and fish oil should be removed and the abdominal cavity should be cleaned.

Removing fishy smell depends on a lot of ginger and wine. If it's steamed, you can't put anything but ginger and wine. Just like steaming other fish, pour it out of the pot and into the soup. Sprinkle onion and coriander, and pour hot oil to stimulate onion fragrance.

If catfish stew tofu in this way, you can also use garlic and pepper to help remove the fishy smell and improve the taste. Finally, sprinkle with shredded perilla leaves when cooking. Many river fish restaurants rely on this catfish to stew tofu!

By the way, catfish are wild, raised in rivers and raised in ponds. Because catfish itself has a miscellaneous diet, and it is a benthic fish, which is commonly known as eating mud. Therefore, it is impossible to get rid of the odor of catfish raised in ponds because the water quality is poor and the pond mud stinks.
