To create a simulated deep-sea environment, just have less light in the
habitat. That should create a suitable ocean-floor environment for anything
you care to have live in it, except maybe whales and other large sea
critters. But, I don't see them being farm-raised for food anywhere, let
alone space. Most stuff that lives in the deep water just likes it cold and
dark, they don't really care about the depth pressure. Not really the
gravity, either; when something is neutrally buoyant, it behaves like it's
almost weightless anyway.

As for range, if a tuna or salmon lives in a cylindrical ocean it can swim
as far as it likes, just as long as it goes east to west. Maybe put a salmon
ladder on the endcaps.
