Lab grown fish are one thing, but simple fish farms already work really well, the issues are that the fish don't eat a natural diet and are sicker and less healthy to eat. Maybe that's an easier problem to solve than growing fish meat in a lab.
Likely we could use both methods and see what works best. I’m not sure how well fish farms scale up but imagine lab grown meats will scale up.

Farmed fish are fed pellets made of wild caught fish though.
That depends on the species. Farmed catfish eat mostly soybeans and corn (maize).

It still means deforestation, biodiversity loss, soil degradation, poisoning the ecosystem with pesti/herbicides and fertilizers on land (with the associated runoff into the waterways) and a lot of organic waste on the water (each salmon farm in scotland produces as much organic waste equivalent to a town of between 10 and 20,000 people each year).
I'm unclear why you'd stop at commercial fishing . Just ban all fishing and all fish consumption. The premise that your children could one day eat fish is the problem
I still think the idea should be discussed and maybe g20 nations come up with some agreements.
Hopefully things like lab grown fish improve and maybe we can move people away from the real thing.
I keep telling my kids they are lucky anytime we get the treat of having some fish as in their future it may not be something available to the common person.
