A Canadian businessman said he has the solution to Maine’s green crab problem: Eat them. The invasive and voracious small crabs native to Europe are devastating the state’s clam fishery. Ron Howse — president and chief executive officer of Tidalwater Seafood Co. in Fredericton, New Brunswick — said the meat of the green crab is sweet and tasty, and he wants to market it to diners in Asia and Europe. The Portland Press Herald reported that he planned a press conference for Thursday in Brunswick at which he was to lay out his plans and even offer some green crab meat to taste. The plans include opening a processing plant in Maine.
