Lawyers for the American Seafoods subsidiaries under fire from the US government for a controversial pollock shipping route from Alaska to the US East Coast are saying hundreds of millions in penalties imposed upon them "will effectively put almost everyone along the supply chain out of business."

The companies told an Alaska federal judge Tuesday they are desperate to get 26 million pounds of frozen seafood stuck in storage in Atlantic Canada moving again, and that the court must grant the companies a preliminary injunction against accruing more US Customs fines in order to stay in business.
