I wonder about engineering yourself a productive fishery instead of exploiting wild stocks.

Most of the ocean is practically a desert. The only productive places are near land, where deep water up wells and returns sunken nutrients back to the surface.

I'm sure we could study and engineer some sort of nutrient dumping and cycling scheme. I bet you could make vastly more food while leaving a lot of ocean alone.

Totally, they do a lot of this, fish farming.

There are places famous for it, and there are other places like French Polynesia where they use existing atols as places to do it.

It's not easy, but it can be very productive.

A lot of their species interests can’t be fish farmed. Some can but it’s not exactly economical to shark farm or squid farm. Mussels, shrimp/prons, clams, salmon, some tuna, trout, and smaller fish can be farmed effectively.

While China dominates the fisheries, Japan is still whaling. The oceanic deserts are getting worse every day.

the bay between shenzhen and hong kong is basically a giant oyster farm which they say also helps clean up the water. so people do it with some stuff

The recent David Attenborough documentary Ocean suggested that the Papahānaumokuākea Marine conservation area off the coast of Hawaii had contributed to abundant fishing stock outside the reserve. It was suggested that if we reserved 30% of the ocean, we would see a huge increase in fisheries the world over.

Another recent discovery is that although we've damaged our fisheries significantly, oceanic ecosystems apparently recover much faster than terrestrial ecosystems if left untouched, within several years.

You don't need to farm squid since it's one of the species that is benefitting from climate change and overfishing. https://www.science.org/content/article/world-octopus-and-sq...
