oama, correct me if I'm wrong, but the clams are still raised in the ocean? I think that when I hear captive bred, I'm thinking, big vats somewhere with little fishies and clams swimming around. I've read Knop's book and seen the pix of captive spawning et al, but my understanding is that while that is part of the management, the grow out etc...is conducted in "raceways" in the ocean. Not that I don't commend the effort to reduce environmental impact, but it's sort of a semantic issue w/terms like CB, CR, TR and "farmed"...BTW, I love your clams and do own a few.
