They move up and down frequently anyway and can vent their swim bladders faster than it changes.

Or put another way, remove our atmosphere and that only equals 10m change in depth to a fish. (an oxygen depleted one). If you want to prove it, then do the math.

Pull a laker up from Depths, then it will have issues.

Any effect your seeing with barometric pressure will be due to things the fish can sense:
1. Sunlight
2. Rain
3. Wind/Waves
4. Water inflow

I.E. Barometric pressure is related to the above but not the cause.
