How do deep ocean fish manage to survive the enormous pressure of water?

By evolving there...
IMO, the main problems that need overcome are the lack of light, the extreme cold, and the relative paucity of food.

Are you calling R-Smith to the quick here?
For me, it's an evolutionary thing.
An adjunct: Why do huge stocks of fish disappear ( Grand Banks or Murray River cod for example)? According to R-Smith and MaryMartin they go somewhere else, nothing to do with fishing. Where is not so easy to nail. Where have all the fish gone R-Smith and Mary?

Don't give us the quota's argument. Where are the fish? ?? Oh yeah it's a big ocean. But it's a small world!!!!!!

In answer to the op: Because they don't have any air cavities. The pressure inside their cells are equal to the outside pressure so the pressure difference is nil. They maintain near neutral buoyancy with oil in their livers.
