There's been some encouraging movement in New Jersey on the dire situation regarding red knots and overharvested horseshoe crabs. Since the NJ Marine Fisheries Council voted 5-4 to lift a moratorium on crab harvests on Feb. 11, there has been a bipartisan movement in the state legislature to institute a permanent harvest ban.
You can read updates on the situation from New Jersey Audubon here. And you can read a recent news report from the Asbury Park News and a far less objective piece from the Press of Atlantic City, which focuses only on the watermen's views. (One could argue, for example, that a resource management council comprised primarily of commercial fin-fishermen, shellfisherman and fish processors constitutes a "special interest" of just the sort criticized.)
