If you were attempting to spear a fish, you would aim below the observed fish to make a direct hit. Would you do the same if you used a laser light to "spear" the fish?

yes, you would aim below the fish.
the light you see from the fish is refracted when it leaves the water and enters air, and since it goes from a denser to less dense medium, the light bends away from the normal
the light that enters your eyes appears to focus at a depth shallower than the fish really is, so you would aim below the apparent position of the fish
