Google/Wikipedia describes efforts in fish hatchery cultivation of AG. Great idea if they can get it to work
but no two fish species are the same in a hatchery.
I have a few years experience in a small Pacific salmon hatchery. Annual release of 75,000 - 90,000 fin-clipped fingerlings.
4 years later, not one in a thousand returns to their spawning river. Discouraging but better than nothing.
I'd prefer to take scale pictures, a skin/scale/scute sample and release to breed more of that successful individual.
Problem is, some fish species, after a big fight, are so loaded with muscle lactate that they can't metabolize it all
and they die anyway. For example, scoop a goldfish out of a tank in a little net. Let it flop around for 10 seconds.
Put it back in the tank. The shock of capture and struggle can be measured 3 days later.
