On big fish we catch and release we pull them along side the boat, and cut the line with a fillet knife, as close to the cheek as possible. We were told the hooks actually rust out in a very short time and pose no danger to the fish. I didn't watch the video, so I didn't see how much line was left with the hook. This one we boated for pics, so we pulled the hook.So they just cut them loose with the hook/line still stuck in their mouth?
