If you choose to help and it is safe for you and the turtle:
[SIZE=4]REEL-IN[/SIZE] turtle with care. Please bring in the animal for disentanglement. Do the best you can to reel-in (land) the animal carefully. DO NOT drag a turtle up a cliff.
[SIZE=4]HOLD [/SIZE]turtle by its shell and/or flippers.
[SIZE=4]CUT [/SIZE]line close to hook as short as possible .
[SIZE=4]REMOVE[/SIZE] the hook only if it can be done without injury to you or the turtle. If the hook barb is exposed smash the barb down to easily extract the hook and shorten the handling time of the turtle. DO NOT remove the hook if swallowed. If using a barbless hook, then the hook should easily come out.
[SIZE=4]RELEASE [/SIZE]turtle with no line attached. Remove any line from flippers, head and neck. Help to remove any remaining line from the reef. Dispose of the line in a responsible manner.
FYI!
