Living a few miles outside a town of 700 or so people in the middle of nowhere (Nebraska), I have the choice of one grocery store. They do carry some frozen fish. However, it is generally farm raised fish from China like tilapia and salmon. Is that really a good choice?
Frozen fish can be a good choice, especially in a situation where you might be in "the middle of nowhere."
Much of the fish at the big grocery store chains has been shipped to them frozen and then thawed at the fish counter. This is the much of the same fish that you find in your freezer case. Some of it is farmed and others caught wild and then quick frozen. Much of it is then vacuum packaged.
Because of this you may be in better control by choosing frozen fish than if you bought fish from some grocery store fish counters that might not treat the fish as carefully as you might.
