Explanation of what @NCbassraider is referring to. Bass have a thin, protective slime coating over the whole of their bodies, shielding them from harmful bacteria and parasites. This slime coat gets removed through contact with hands, boat decks, grass and fish rags. In addition, boat decks are usually fairly hot and can actually burn the side of the fish. Many times the bass is not flopping because it's trying to get away, its flopping because its getting too hot.
