Marine biologist Kat Bolstad holds a twig of black coral recovered from the bycatch discarded from a deep water trawler in international waters in the Tasman Sea. Black coral is protected in adjacent NZ waters, and is listed under the international CITES agreement. Greenpeace along with more than a thousand scientists are supporting the call for a moratorium on high seas bottom trawling, because of the vast amount of marine life that is destroyed by this fishing method.
