I am seriously thinking about starting a small sandworm farm

[Swimmer]

It worked for the Sea Bait guy, because he started the company as the end result of Masters thesis/project in England. He was born in Mass.(Hopkington). The school floated some of the money and he solved his water tempt problem by locating on vacant land around an energy plant next to the ocean. Warmer water was always available. All he had for ponds were cinder block circle with black plastic tarps as liners. He said he made a mistake moving to Maine not realizng how cold the winters become. Had to build a structure with shelved beds made out of 2 x 4's and 2 x 6's again covered in plastic. Sand of course is lined on the bottom and is suctioned out at the end of the growth cycle onto srceens and voila there are your worms. Guy said there was a noticable difference in growth rates when water is warmer. Pete Santini of Fishing Fanatics on the North Shore is close with the owner. I asked him if the worms were the same at ther diggers sold him and he said no difference and the wholesale price to him was the same, so it must be financially feasible to market the worms. Thier being sold up and down the east coast. Your either going to need a structure though or a warm water source I think to be effective in the northeast.
