For ~200k years, humans got food from hunting and gathering. You went out in nature and caught the food you could find growing wild there. That supported a global population of ~50M.

10k years ago we started figuring out how top make food ourselves (farming), and now we can comfortably feed 7000M.

But we still harvest the oceans like hunters and gatherers. I don't think this can or should go on. We need to farm the oceans!

See my comment above. Marine wildlife sanctuaries are very effective at replenishing stock.

Also, it’s not always realistic to farm fish. It’s not always possible. And the quality is often much worse given farming practices.

That's completely true with current technology. I'm talking about the long term future.

It took 10k of farming before fertilizers were invented in 1913 and doubled food production.

Yes, much of the ocean is basically a desert due to a lack of iron. Low iron leads to low plankton which leads to low fish counts.

Ocean fertilization could 10x the number of fish, and possibly store some carbon also.
