Most of them were redhorse. We got a few whiteys in the mix too.
There are around 5 different species of redhorse in MN, and I'm not too sure how to identify them. I will tell you that it was a mixed bag. Most of the fish were the really big ones with lighter skin and fins, but we got some with the dark golden skin and darker red fins too. There were a few in the mix with smaller heads and bright red tail fins too. We only caught a few white suckers, but they usually don't run at the same time as the redhorse. I cant remember if they run earlier or later than the redhorse.
I will say it was sure good fun! I am going to try a few more times before it is done with. It is a fantastic opportunity to put a kid on plentiful large fish that are stupid and easy to catch. Jimmer had a BLAST fishing for those smelly things! It started to downpour rain and he still didn't want to go home. If you want to get a kid addicted to fishing, this is a great place to start.
