I asked a question recently, Channel Catfish vs “Bala Catfish” … how can I identify which was sold to me? which was edited by another user because I had mentioned the fish were being raised for food (aquaculture). The comment on the edit was "We don't eat our pets", and the human consumption note was removed.
I searched Pets Meta and only found: Where is the line drawn for feeder animals? which only talks about feeding animals to other animals, not to people. I'm going to go off on a hypothetical tangent here and suggest that based on the attitudes and opinions expressed in that question, had I instead mentioned I was raising catfish to feed to a much larger predator (dolphin, killer whale, blue heron, ??? etc), that would somehow be morally different.
If questions about raising fish for food are not acceptable on Pets, then where would I post such questions? There is no agriculture or aquaculture stackexchange, nor is Gardening and Landscaping a proper place for questions about raising animals.
