A group of leading members of the British Parliament are criticizing the Marine Stewardship Council (MSC) for allowing what they described as the partial certification of fisheries.

The standard allows fisheries to be MSC certified and for vessels to operate both with and without fish aggregating devices (FADs), even if the FAD system is unsustainable, said MPs Richard Benyon, Zac Goldsmith, James Heappey and John McNally.

The criticism is the latest fallout from the potential recertification of The Parties to the Nauru Agreement (PNA) tuna fishery, which the members of Parliament said would allow products caught in the fishery to carry the MSC logo even though unsustainable FAD fishing takes place at the PNA.
