In this Oct. 28, 2003, file photo, a small dusky shark flails on the end of the Avalon Fishing Pier in Kill Devil Hills, N.C., as angler Ron Warlick gets ready to remove the hook. A group of conservationists say a federal plan to protect this threatened shark that lives in East Coast waters doesn’t go far enough. The National Marine Fisheries Service is proposing changes to federal fishing rules with the goal of protecting dusky sharks.
