Conditional on fish actually being able to feel pain, it seems a bit far-fetched to me that a slow death in ice wouldn’t be painful.
This is less clear for shrimp, though. I don’t know if they find the cold painful at all, and it might sedate them or even render them unconscious. But I imagine that takes time, and they’re being crushed by each other and ice with ice slurry.
