From my understanding which is limited there are "blues" in Lake Erie too. The "blues" are just a sub-species of the eye tribe. Take photos to share the next time you all catch them, to share with us ;) DD your probably right with the notion that they are more of a silver than the typical black and gold and the bluish cast coming from the refraction of light through the their covering of slime ;) Sounds like a good photo op to me ;)
