BELFAST, Maine (AP) – A Maine-based smoked salmon producer is defending itself against claims that its products are not sustainably produced.

A New York resident alleged in a lawsuit that Ducktrap River of Maine does not use sustainable practices despite the labels affixed to the company’s salmon products.

Mowi ASA, a Norwegian company that operates Ducktrap through a subsidiary, denied the allegations in a statement, saying its products are “sustainably and responsibly sourced. Following a rigorous certification process, Mowi has been recognized to abide by industry best practices for sustainable aquaculture.”

The lawsuit seeks class action status and unspecified damages, which could increase if a court found that the company willfully misled consumers.

The lawsuit argues that industrial fish farming endangers public health, causes animal suffering and environmental damages.
