I saw a family of mergansers diving in shallow water (~18 inches deep) by these rocks where I’d seen little fish before. After the birds had gone, I set my camera down there for an hour and 40 minutes in three different locations. Here I have condensed all the fish that swam by = three minutes of footage. If you wonder what mergansers eat, this is like a drive-thru restaurant for them. I would appreciate any help with identifications, there are at least 4-5 species represented.
Responding to a comment about how some of the fish seem curious about the camera, part of the reason may be it is simply blocking their way. This area of interspersed boulders is a maze-like bunch of trails for them to zoom around in all day. To keep my camera from floating, I had to pile rocks on top of it, essentially blocking one of their thoroughfares. Several fish come up to it in transit and squeeze over top of it or around, others turn back and go the way they came, adjusting their regular routes.
Lastly I will add that several times, pairs of fish (I don’t know what kind they are) seem to be playing. I think these may be the same pairs each time they appear. I have named the most prominent ones Herbert and Gerbert.
