Cleaning a Redfish

From Ron Brooks, former About.com Guide

While holding the skin with one hand, continue running your knife in a sawing motion under the meat of the filet. The meat will separate and leave a very nice filet. To cut out the rib cage bones for a boneless filet, first find them with your fingers. They will run from the middle of the filet down and through the stomach portion. Place your knife along the edge of the bone line and cut this portion off the filet.
