What does safe handling and release mean?
Safe handling and release (SHR) refers to using best practice methods for dealing with bycatch species, to maximise their chances of survival after interacting with fishing gear. It can also include vessel manoeuvring to avoid taking bycatch species, for example, avoiding setting purse seines on whale sharks.
In purse seine operations, bycatch can be released from the net whilst in the water or released once brought on deck and free from the brailer. For example, dolphins can be released from purse seine nets using a 'backdown procedure and Medina panel'. For whale sharks, if they can be brought close to the hull, crew may be able to 'stand' the animal on the net and roll it outside the bunt. Very large fish, like large sharks or manta rays, can be returned to the sea from the deck using a piece of net or a piece of plastic canvas that can be lifted by the crane.
With line fishing operations (longline, troll; there is little bycatch in pole and line operations) bycatch may either be released from the side of the vessel or after being brought on board, depending on size. For example, a dip net can be used to bring smaller turtles onboard, after which a piece of wood can be placed in the turtle's mouth so it cannot bite, then the hook or line can be cut.
