I'm a spectator of the obscure and there's no limit of obscure where I live.
Elver fishing has fascinated me since I moved to Maine. The tiny glass eels(Elvers) are on their way toward streams on Maines coast after a long swim from the Gulf Stream. They rode the stream from the Sargasso Sea(southwest of Bermuda) where they were born not long ago. That was thanks to their parents that made the trip(their last) to the Sargasso from lakes and little ponds in Maine upstream from harbors like Rockport.
Licenses are only issued to those that held them before. When prices rise, things can get touchy. I saw a brawl in Camden Falls the first year I lived there I've been following the event ever since.
Prices used to go to 250-300.00 per pound(Price can also sit a 30.00/pound with no demand). Last year, many supplies to Asia dried up and Elver prices rocketed. A pound of these little nearly invisible glass eels, for a time in 2011 fetched,.... $900.00 per pound. Two guys that had a good day netted over 46k at one wholesaler. The Elvers are fragile and are shipped live to destinations in Asia where they're raised in pens. the adults are a delicacy there. Some restaurants serve the little eels even in the US, but at $900 a pound, that's a pricey appetizer.
Heres' the Elver dance traced by their headlamps.
