Bukaty, File)PORTLAND, Maine – Maine's baby eel fishermen are hopeful for a more stable season in 2021 as they seek one of the most valuable natural resources in New England. The fishermen seek the eels, called elvers, so they can be sold as seedstock to Asian aquaculture companies. Eventually, Maine fishermen harvested almost all of their baby eel quota, which is a little less than 10,000 pounds for the entire fishery.
