A lot of deep see fish die and/or severely deform when they’re brought to the surface for study. Why not put them in a pressurized container so they can be preserved in a way that leaves them the same?

Most deep sea fish we find are like.. dead already and we study the corpses
Going down into the depths is already difficult enough with a research submarine, if we are lucky the submarine has some arm to study samples and such…
We tend to not.. grab animals down from the depths and bring them up here usually, we study living samples in their envoirement, while we see a lot of dead samples that cannot keep shape.
We can technically do that stuff with the pressurised container but usually theres no good methods to.. catch the animals nor the need for it…as collecting data on lifeforms is generally best done..in their envoirement.
Unrelated but: it is a general criticism of zoos.. you cant exactly study animals well in captivity because their behaviour changes there. We wouldn’t get good information with this. Also just like keeping great white sharks and such in captivity…ecosystems are difficult..in order to keep and capture and study something and keep it alive we gotta understand more about the envoirement they live in.
They do that sometimes. I’ve seen a deep sea exhibit in a public aquarium where the tank was pressurized. It’s way harder, and therefore way more expensive and less common.

I mean you could but you wouldn’t really be able to study it without breaking the seal of the container. To get anything in or out you’d need an additional chamber that would pressurize before opening up to the internal chamber. I guess you could get somebody inside with a scuba suit but it’d have to be massive and I’m not sure how safe it is to pressurize a tank of water with a person in it. You’d essentially have a really expensive aquarium with a dead fish in it

See my other comment, but as a matter of fact, [we do it sometimes.](https://sci-hub.st/10.3389/fmars.2018.00187/full)
