Yikes

This link about commercial fishing and how fish are treated is deeply disturbing. Today someone told me crabs are also boiled alive and they flail violently as the water gets warmer; to me this is a response to a stimuli they perceive as threatening and dangerous -- I'd call it at least *fear* if not pain. It seems impossible to me that these animals don't suffer. They do, maybe in a different way than humans, but still they suffer.
