This minnow was caught and released in the Baron Fork River in northeast Oklahoma.  I was thinking either a big eye chub (Hybopsis amblops), but the lateral stripe wasn't very prominent in this specimen or a Hybognathus  spp. but I have always thought they were usually caught in sand bed streams.  Any ideas?

Ozark Shiner, N. ozarcanus??

 

That is in the Illinois drainage, right?

 

I'm really not that good at out of state shiners.  I guess I should be better since the NANFA convention was in Tehlequah last year.

I am thinking H. amblops as well.  Although, every specimen I can find has a distinct black lateral band which this fish is lacking.  Yes, this is the Illinois River drainage.

I've never seen the western Hybognathus species, but that guy sure does look a LOT like our eastern Hybognathus.

I've seen Hybopsis amblops in western NC, and they look quite different from your fish.  So I'll guess Hybognathus.

I think you guys are right with Bigeye Chub.

A closeup shot of the snout/mouth and underside of the head showing mouth shape would help distinguish Hybopsis amblops vs Hybognathus.  Also would like to see the caudal peduncle - any trace of a caudal spot?.  H. amblops should have some dark scale edge pigment, at least on the upper part of body, and a caudal spot.  Did the body have any more pigment than we see here when you first caught it?  If it was in a white bucket for awhile before the photo shoot, much of the pigment could disappear.

Amblops.

 

 

 

  My best guess at least from the few I have known. I have no business sounding 100% confident.

Could be H. amblops we did catch them in the Illinois River, they were pretty common at the site we all sampled there. I'm not convinced though, could just be the angle that it is sitting at but I feel something is a little off. I might lean toward Hybognathus but I have little to no experience with those, only seen them once in person in WI.
