I would guess a Luxilus.  Not sure what's in your area.  L cornutus?

Agree with Mark ... Luxilus cornutus, common shiner.  Note the scales behind the gill appear taller and narrower than the scales farther back.

Common shiner? I am very surprised. What surprises me is that the body is not nearly as deep as the fish that I have caught before that I thought were common shiners and not as deep as the illustration in Peterson. Also, I have never seen one with a prominent black stripe running down the side (which also is not mentioned in Peterson).


Could it be a mimic shiner? They were introduced into the CT river, and the Farmington is a tributary of the CT. The black stripe on the side matches mimic shiner photos and the body depth is consistent also. The tall, narrow scales behind gill also match mimic shiner descriptions.


You have much more experience at this than I do, but it just doesn't look quite like any photos of the common shiner.

Yours is still a juvenile. The body will deepen as it matures.

Yep definitely common shiner in my opinion as well, it is a young one and some of the features your not seeing will develop more on larger fish.

I would've said Common Shiner, too.  Can't be 100% sure, though, as I haven't collected in your area.

Most fish ID books only show adults, or they may show juveniles of "important" game species.  A few books show both adults and juveniles of most species where the ID characteristrics are different for adults vs juveniles.  Freshwater Fishes of Virginia (Jenkins & Burkhead 1994) is one of those.  For Common shiner it only shows an adult, but it has juvenile photos of the closely-related White shiner and Striped shiner (pages 374 and 379), both of which look a lot like your fish.  To me the head/mouth shape doesn't look right for Mimic shiner, and I'd expect Mimics to show more dark edging on the dorsal scales usually, but of course that pigment can come & go with the fish's mood.  Also, how big is this fish?  Mimics are usually less than 3" total length.


Did you see this little Common shiner that Fishy Jackson caught recently in eastern NY ?

Yes, commons resemble just about any other silvery shiner when they are small. it's why I held off on answering, (that and I could not find a species list for his river to narrow down choices).
