Ah, c'mon, you know better than that. Oysters are bivalves, and there is some protocol for their farming and collecting. Lots of investigation for some degree of sustainability. There's more control over their use than with cuttlefish. Show me an impact assessment that's been done for the world's cuttlefish stocks and I'll consider it. It's no good to say something's a less damaging alternative just because impact assessments for it don't exist.



It's easy to slip into double standards when we deal with captive animal issues, especially when we do it under the name of conservation. Do consider, oysters are not harvested for their shells, but rather, everything inside the shells. The shell is a marketable side perk. It's sold because it can be used instead of thrown out. If the shell couldn't be used, all those oysters would still be harvested. Were it not for your demand, bird keepers, and part of the jewelrey industry, there wouldn't be much initiative for cuttlefish removal because the primary demand (cuttlebone) would be gone.



Use chicken eggshells if you demand a crunchy calcium source. Another byproduct, also somewhat controlled. But, do we use freerange chicken eggs only? White or brown eggs? Oh, bother!
