Restocking could have the same effect as replanting trees: numbers stay the same so it absolves the industry.

But the ecosystem is still getting worse as it gets devastated by the constant churn and artificially restored new areas are not as diverse as the original one.

I'm pretty sure wild fish restock themselves by reproducing, it's more about finding the equilibrium it converges to and not overfishing.

In Vietnam, marine wildlife sanctuaries help enormously. Fisherman are banned from fishing in certain areas, but can fish with great success around those areas. The protected areas allow stock to be replenished. It’s the goose that laid the golden egg phenomenon.
