Ok, so the story on the 2002 blue cat record was the guy brought the fish over from another state to claim it as the MN state record. Somebody turned him in and his story kept changing. So he got pinched for lying on a state form and for transporting fish across state lines without a permit. Think he brought it over from South Dakota/Missouri River.
Blue cats may be here. If they are, they are rare. We are within their original native range but the lock and dams likely responsible for their decline. MNDNR stocked a few thousand small blue cats in the St Croix in the 70’s or 80’s. None were ever positively identified from that stocking.
If anyone ever catches one, get pictures or bring it in. Focus on the anal fin, don’t bother with the teeth.
