August 25, 2026 — On January 1st, 2026, NOAA Fisheries implemented new import prohibitions under the Marine Mammal Protection Act (MMPA), banning seafood imports that failed a comparability finding. According to the findings, 240 fisheries from 46 countries failed to adequately protect marine mammals and were subsequently blocked from exporting their products to the U.S. Eight months later, this policy is noticeably affecting companies that produce the now-banned products. But the impact on the water is more difficult to measure and may not be going as NOAA intended.
I purchase seafood for a U.S.-based importing company that specializes in sushi ingredients. We recently visited a yellowfin tuna first receiver and processor near Tuy Hòa, Vietnam, and asked how operations have changed since the import ban on January 1st. This company processes yellowfin tuna for raw consumption, exporting “sashimi-grade” products to Europe, Japan, China, and its largest market, the U.S. Some of the raw material is handline-caught from a nearby fishery improvement project. This fishing method met the comparability study standards and has not been banned. But when handline fishing is slow, as it has been in recent years, fishers deploy gillnets to boost their catch. NOAA’s comparability findings determined that yellowfin tuna caught using gillnets do not meet MMPA standards and therefore can no longer be imported when caught in Vietnamese fisheries.
