Several years ago, I went on my 1st drum trip and caught several. After we took pictures, we put them back and sorry to say, several floated away, out of site. The capt said they would be fine but I'm thinking probably not. They were healthy going back into the water so I'm not sure what happened. This happened to a 30lb and 80lb. Is there a swim bladder that you have to push on, so that they release what appeared to be a belly full of air?
