Fishy policies

Of the five known species of arapaima, three have not been observed in the wild in decades, according to study co-author Donald Stewart, a professor with the State University of New York at Syracuse's College of Environmental Science. Stewart said that all five species dominated fisheries in the Amazon just a century ago.

A commercially important species, arapaima are traditionally fished by local Amazonian communities, a practice that's largely unregulated, the researchers said. To find out how this lack of regulation might be affecting the giant fish, the researchers interviewed local fishers operating within a 650-square-mile (1,683 square kilometers) floodplain in northwestern Brazil.
