Bumble Bee Seafoods on Wednesday said it had signed an agreement to buy "sustainably" caught tuna from a group of mostly island nations in the Pacific.

Bumble Bee made the deal with Pacifical, a marketing company created by eight countries, including Papua New Guina, Tuvalu and the Federal States of Micronesia. The countries are known as Parties to the Nauru Agreement and control about one-quarter of the world’s tuna.

Terms of the deal were not disclosed, but Pacifical said it would give Bumble Bee full “traceability” for the tuna, which will allow it to determine the exact ship, captain, fishing method and catching period associated with the tuna it buys.
