A reminder that eels are critically endangered and are still a major part of the licit and illicit economy in Asia, Europe, and parts of the US (lookin’ at you, Maine)
Valuable eels are in decline all over the world, leading to a new push for restrictions on trade to try to help stave off extinction.
Eel populations are falling, and new protections were defeated. Japan and the US opposed them
