You will definitely get dissenting opinions from mine on this, but I think it's okay to eat farm raised fish. While it is unlikely to have the quality of wild caught fish, it is still good for you, and better than not eating fish for sure.
con is what they feed the fish and the environmental damage farming fish does on surrounding water.. so even if you think you are doing good not depleting the oceans of fish, you are still hurting ocean fish from the run off
also keep in mind near 100% of the fish you buy from a supermarket or restaurant is farm raised, even if they claim wild. there is a lot of loose loopholes
