If you can’t justify a large chance, just using a small chance instead allows you to be Pascal mugged when that small chance is combined with a calculation that shows a huge amount of suffering.
This is true—but the logic wrt brain function says to me that the proper chance that fish suffer is very high. The neural circuits are different in complexity but not fundamental type (representations about the world including bodily state, etc) from humans.

Pascal’s mugging usually involves tiny probabilities though, and you need to have pretty darn confident philosophical beliefs to go below 1% here.
