Done this for years. Works great. You can also make a tool using a metal coat hanger. Cut off a piece 12 inches long. Then put a U shape bend in the wire on one end. This works great on the smaller fish to not damage there gills by running your hand up there. Just push the wire up below the gills, catch the line, pull the line out, then go in from the mouth with pliers, and grab the hook as close to the center of the round bend of the hook and pull out gently. Know telling how many fish this technique could save if everyone used it.
