Not uncommon at all coming out of winter as the days get longer. In March I see this all over Texoma in LMB. I see 1-2 in my SMB every year. It's (I believe) a behavioral trait.
Snipe,
If you think it could be behavioral AND you see it coming out of winter, do you think that the fish are "sunning" themselves to get warmer in the shallowest water? (About 50% of total UV radiation can reach a foot deep in water.)
Do the black spots disappear later in the year? (For either Texoma LMB, or your own SMB.)
