I recently looked at a study about largemouth bass and discovered that in at least one lake, they don’t appear to be bothered by motor noise. Even if the boat is maybe 5 meters away.

They also appear to have interesting and unexpected seasonal migrations and spawning patterns. They will situate themselves for prolonged periods in very different parts of a lake, over and over. Almost like they have vacation homes, haha.

But perhaps most surprising to me was their lack of response to loud motors and water disturbance by boats.

I have no doubt motors do spook some species, like trout or salmon.
