Shark bycatch (longlines)

Globally, it is estimated that between 63 to 273 million sharks are bycaught annually in commercial fisheries. Currently, one quarter of chondrichthyans (shark, ray and chimaeras species) are classified as threatened by the Red List criteria of the International Union for the Conservation of Nature. Pelagic sharks and rays comprise a high percentage of the catch in pelagic longline fisheries as either target, byproduct or incidental bycatch (e.g. ~25 per cent of the catch). This has led to overfishing of several species of pelagic shark commonly captured on pelagic longlines targeting tuna. Find out more about SharkGuard and its development here.
