FREEPORT - Long Island fishermen are calling for changes to federal regulations and say they're sinking under the weight of obtrusive and unnecessary laws.A federal law known as the Magnuson-Stevens Act aims to rebuild fish populations, but fishermen claim the law is too restrictive. It prevents them from catching fish under a certain size and restricts when fishermen can catch certain species. Charter boat owners say the laws are hurting their business, too. They say many recreational fishers don't want to waste their time heading out on the high seas to come back with nothing but memories. Sen. Chuck Schumer (D-N.Y.) is trying to throw fishermen a line. He says he's secured a commitment to hold a congressional hearing on the Magnuson-Stevens Act. It expires next year, making the entire law fair game for an overhaul.
