Catfish fishing is a technique that is growing more in recent years. There are many followers of fishing for this "monster" of fresh water. The catfish (Silurus glanis) is a fish that is not endemic to Italian waters, in fact it is an alien species introduced into the basins of Northern Italy about 50 years ago. It loves to live on the seabed hiding in the mud where it rests during the day. At night, however, its predatory instinct is activated, bringing the fish to approach the surface.
