I am not sure that is good advice. Fixing the fishing industry is important, overfishing is rampant as is plastic waste from it. But fish is probably one of the best alternatives we have to other environmentally unfriendly meats we currently raise. As populations grow it is proving to be key to keeping everyone fed. Farmed fish most importantly will soon be the majority of fish consumed.
Getting ocean based fishing to not use plastics will be very difficult but moving the majority of fishing into farms by making it more profitable could very well make that problem go away by reducing ocean fishing in general.
Make trade restrictions on non-farmed fish and the demand for ocean fish from nations fishing with plastic would hopefully go down. If fish from the ocean now contains plastic it would probably be a health boon to only accept farm fish anyway.
You might create a new problem of corporate fish farms decimating local fishermans livelihoods, which sucks. But at this rate they will overfish and pollute their own jobs away anyway.
