This week saw a significant milestone for fishing in the Eastern Tropical Pacific. More than 65 years since the formation of the Inter-American Tropical Tuna Commission (IATTC) – established to manage fishing efforts between 21 countries – skipjack and yellowfin tuna purse seine fishing by the major Mexican fishers in this region has been certified as sustainable to the MSC Standard.
