Wash the fish thoroughly, clean it, cut off the fins and remove the gills. Cut along the abdomen, gut, cut inside, freeing the spine. With scissors, “bite off” the vertebral bone near the tail and near the head, remove part of the spine. If you take out the meat, you can cut it off and put it back just by putting it in place. Our goal is to remove as many bones and other things as possible without damaging the skin, so that in the end we can sew up the fish. We stroke the fish from the inside so that you can feel the bones, remove them. Season the fish with salt and pepper from the inside.
