Sainsbury’s has announced that all of its canned skipjack tuna from the Maldives will be certified by the Marine Stewardship Council as of next year.

The retailer will roll out MSC-certified Maldivian skipjack tuna under its own-label range in April 2013, to complement its canned Albacore tuna, which is already MSC-certified.

Twelve of its 18 lines of skipjack tuna were sourced exclusively from the Maldives, it said.
