Bycatch (IMAGE) Virginia Institute of Marine Science Caption Derelict gear can harm ecosystems and economies by trapping and killing targeted and bycatch species, damaging marine habitats, and competing with actively fished gear. Here, an oyster toadfish (Opsanus tau) is trapped within a derelict or "ghost" crab pot pulled from Virginia's York River, a major tributary of Chesapeake Bay.
