The Northeastern Tropical Pacific Purse Seine yellowfin and skipjack tuna fishery achieved MSC certification in 2017 following a two-year, detailed assessment. The fishery is managed by the Pacific Alliance for Sustainable Tuna (PAST) comprised of four leaders in the Mexican tuna industry: Grupomar, Herdez del Fuerte, Pesca Azteca, and Procesa.

Each team of fishermen works proactively to minimize impact on the ocean ecosystem including aiming for 100% live release of all non-target species. Their efforts include using a specially designed net that incorporates a fine mesh safety panel, known as the ‘Medina Panel,’ which allows non-tuna species to swim clear of the net. The industry also employs highly specialized and trained divers to assist any remaining dolphins with escaping the net prior to lifting the net.

The fishery operates in compliance with all requirements of the Inter-American Tropical Tuna Commission (IATTC), the Regional Fishery Management Organization. Importantly, the fishing fleet adheres to the Agreement on International Dolphin Conservation Program (AIDCP), a legally binding multilateral agreement between fishing nations within the IATTC with conservation objectives. The AIDCP was awarded the Margarita Lizárraga Medalby the United Nations Food and Agriculture Organization in 2005 for its “unqualified success” in protecting dolphins and ensuring the sustainability of fishing in the EPO.
