Definition of 'Trap guards (T-bars, otter guards)'

Welded bars, netting or bungee cords placed in pot traps to prevent pinnipeds, small cetaceans, or otters from entering them and preying on the target catch (Noke and Odell, 2002). This technique can also be used to reduce the mortality of bycatch species that may become trapped and drown (Roosenburg and Green 2000).
