NEEDHAM, Mass. — We visit Ellsworth, where at today’s price of $2,200 a pound, there’s heavy competition to net the tiny, wriggling baby eels for export to Asia. We meet some of the lucky few licensed in the glass eel trade, as well as ordinary Mainers whose fortunes have changed thanks to a coveted license. And we talk to Maine law enforcement about the early days of the eel trade, a wild-west scene replete with guns, cash – and eels.
