Fish caught by methods that can also entangle whales, dolphins, and seals will be banned from U.S. import, starting Jan. 1, 2026, according to a recent agreement.Conservation groups earlier this month made a deal with the U.S. government to stop importing seafood that doesnt meet marine mammal protection standards. U.S. fishers must also follow similar standards in domestic waters.The agreement is intended to minimize bycatch the accidental entanglement of mammals fishers werent intending to haul aboard. While many fishers have changed their techniques to avoid catching mammals, there is still work to do.Unintentional CatchesAn estimated 650,000 whales, dolphins, and other marine mammals are unintentionally caught every year. Many of those animals are tossed overboard, and either drown, or die from injuries.Entanglement is a huge threat to these animals survival, Sarah Uhlemann, international program director at the Center for Biological Diversity, said in a news release. The United States has the power to use its enormous seafood market to help the worlds oceans, and its about time we started. The U.S. imports about $25.5 billion worth of seafood products every year. Those imports come from more than 130 nations and include shrimp, tuna, and other finfish. Around 80 percent of seafood eaten in the U.S. is imported. Time for Enforcement?Although the 1972 U.S. Marine Mammal Protection Act prohibited the U.S. from allowing seafood to enter the country unless exporting nations meet the same standards applied to U.S. fishers, in practice the provision was rarely enforced. In 2016, the government began the process to establish which fisheries to ban, but has delayed putting that policy into place.The deal should ensure some relief for threatened marine mammals suffering from bycatch, level the playing field for fishermen working hard to protect marine mammals, and give consumers more confidence that the seafood they consume does not needlessly kill the whales and dolphins they love, Zak Smith, an attorney with the Natural Resources Defense Council (NRDC), said in a news release.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.
