The choice of lobster was because I replied to a comment claiming lobster had become a luxury good, due to increasing rarity.

Here is some index of north american lobster catch: http://www.asmfc.org/species/american-lobster

Looks as though it may have stalled a bit since 2015. But before that lobster catch definitely grew a lot.

Obviously with things like lobsters there'll be geographical variations, but I don't think there's any reason to suppose that lobsters have become a luxury good due to scarcity.
