Are there any viable solutions here?

- Larger vessels can only fish <increased distance> off shore? - Increase 'no fishing' zones which has shown great success in studies creating nursery locations

Even if there is a solution would it be enforced off the coast of Africa? Some nations fishing fleets dont have the best reputation for following rules.

Calculate the maximum sustainable amount of fish that can be caught/harvested, limit the world-wide production to that and let the market handle the rest.

Those limits would have to be enforced useing armed boats however - else I don't know if there would be an effective way for those huge swimming fish factories to just catch everything until the ecosystem collapses.

Then you'd also need a mechanism so make it socially balanced, or we'd pretty much ban low-incoming fishing societies from consuming their own product.

My humble opinion, not an expert.

This is almost up there with "people shouldn't have kids they can't afford to take care of". The world's appetite for such drastic measures is not anywhere close to being there yet. As evidenced with how barely-able we are to get people to kinda pretend and kinda do something but not really about something as simple as dirty-coal burning, or throwing plastic trash into rivers.

You could try to privatise ocean fishing populations; people are typically more careful with their property.

I guess look into whatever we are doing to deter poachers of farm animals (especially for open grass land farming, the strategies used to protect barn animals might not work)?

Au contraire, what has actually been quite successful in the North Atlantic for the past four decades is the extension of territorial water limits out to 200 nautical miles and beyond. This is coupled with coast guard-enforced fishing quotas set by an independent panel of biologists. The fishermen complain loudly of course, which is a very good sign.

Sorry, what I meant to write is more like 'really nail down the ownership rights, and have someone who's responsible'.

'Privatise' was just the short-hand I picked for that, but making a government responsible can also work, if you have one that functions well enough.

What doesn't work is having only nebulous responsibility at best, no clear rules apart from 'first-come-first-serve' / take as much as you can.

Not fish-farming salmon?

Yeah, Chinese fishing fleets are a serious problem. Any solution would have to address them to make a difference.
