Inuit say that the noises a large ship makes scares the marine mammals away. I'm sure this is true to a certain extent, but a plethora of large mammals live peacefully in harbors all over the world, so it's not the hard fact they think it is.

My guess is the reason Inuit see less belugas is because when they find a pod, they slaughter the entire fucking group. Brag about unborn babies pulled from the mother's womb, etc.
