Yes, fish and shelfood farms are a good idea. My opinion.
I don't like the taste or chemicals used in some of them, though. That needs improvement for me to eat it. The farm raised salmon tastes like trout to me. Again, just my opinion.
They've tried all around the world with salmon, trout and other species. Shellfish are grown that way, too. Oysters, Scallops, Shrimp.
The main problems include: what to do with the waste water (which often includes chemicals and antibiotics), public acceptance of new food, and costs to raise and maintain.
Some farmers have been caught dumping their polluted waste waters into public rivers and lakes.
Is it fair to the fish? I don't know. That's an animal ethics question. I do respect that some people feel that way. I don't know the answer to that. If a person eats fish, and wants them raised in a "humane way", then that needs to be addressed as a concern.
If they can solve these problems, I think it is a VERY good idea to farm raise fish for human food. The scraps are great for pet food also.
To summarize, yes, I think it is a VERY good idea. There needs to be more public acceptance of farm raised fish as a menu alternative to beef, pork and chicken, and the pollution aspect needs to be dealt with.

How do I know all of this.... well .... let's just say that a person I know well is a fish biologist, with over 50 years experience in the US and a world-wide consultant. Some of our friends and acquaintences did try farming fish. The market in our area is too flooded with fish, though. The price used to be $7 a pound retail, now it is $2 a pound. The profit margin for farmers is too low at this current price point.
