- 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.
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.

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)?
'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?
