There are two ways to clean a catfish. The easy way "in the first video" and the hard way in the second. The easy way requires you to have an electric knife and be willing to hit a couple bones. This is the preferred way if you have a big cat to clean. The hard way is to use a fillet knife a skinnier and gut it. The second way is more time consuming but if you have a small catfish and no electric knife you might want to go that route. You should always was the blood off to get the fishing taste out. You can also trim the dark meat as well. If you have any tips post them below.
