I didn’t know that, and think it’s really cool in terms of preserving established stocks. Caviar is one of my personal favorites.
Yah. Why the hell kill the fish? Can you even imagine killing, say, a chicken to obtain one clutch of eggs and then having to go raise another chicken. The traditional harvesting dates back to AT LEAST the 1100s, and likely earlier, and I for one will not be sorry to see it gone (which it will be, for economic reasons and not PETA reasons).
