Don't need a glove, just know the location of the spines so you can get your hand behind them. Easiest way is to hold the fish, and slowly slide your hand up behind both pectoral fins and the dorsal fin, pushing your hand behind the spines on the front of each fin. You rest your thumb and index finger right up against the bony spines with the palm of your hand on the top of the fish, and the dorsal spine resting against the curve between your thumb and index finger. Squeeze firmly, but not too firm so as not to hurt the fish. You just need to squeeze enough to keep your hand close to the base of the spines, not near the sharp point, and to keep the fish from flopping.
I personally love catfish. They're fun to catch. Used to catch em all the time on Lasalle throwing leeches on a slip bobber rig up by the riprap shores. They're good eating too. Fried up catfish chunks are great!
