December 1, 2025 — Eels are the stuff of nightmares — slimy, snakelike creatures that lay millions of eggs before dying so their offspring can return home to rivers and streams. They’ve existed since the time of the dinosaurs, and some species are more poorly understood than those ancient animals.
Yet they’re also valuable seafood fish that are declining all over the world, leading to a new push for restrictions on trade to help stave off extinction.
Freshwater eels are critically important for the worldwide sushi industry, and some species have declined by more than 90% since the 1980s. The eels have succumbed to a combination of river dams, hydroelectric turbines, pollution, habitat loss, climate change, illegal poaching and overfishing, according to scientists. Some environmental organizations have called for consumers to boycott eel at sushi restaurants.
The loss of eels motivated the Convention on International Trade in Endangered Species of Wild Fauna and Flora, or CITES, to consider new restrictions to protect the wriggling fish. The members of CITES, an international treaty, met in Uzbekistan this week to determine if the new rules on trade are needed. Member nations voted against the new protections on Thursday.
Conservation groups said the protections were long overdue, but not everyone was on board. Some fishing groups, seafood industry members and regulatory agencies in the U.S., China and Japan — all countries where eel is economically important — have spoken out against restricting the trade.
