Fishermen in Maine say they aren't surprised that regulators have canceled the shrimp season, but it still hurts.

The decision to cancel the season for the second year in a row was made at a meeting Wednesday in Portland.

It has the biggest impact in Maine, where fishermen caught nearly 90 percent of the small, sweet shrimp in the winter.

This is the time of year when ground fishermen would switch over their boats for shrimp season. Instead, Randy Cushman, a fisherman in Port Clyde, Maine, is preparing to continue ground fishing over the winter.

"We've always relied on ground fishing and shrimping," he said. "Always had one fishery or the other to bail us out year after year. Now we've lost the shrimp fishery and ground fishing hasn't been able to compensate."

Scientists say warming ocean waters is part of the problem. Some fishermen also believe over fishing is to blame for the collapse of the stock.
