I never heard of this at all. I do know that ODW ask people not to dump unused minnows into the lake. Most bait shops get minnows from out of state, usually the Dakotas/Mn/ or Arkansas. All them have species not native to Ohio waters. Also, be careful when using minnows seined or trapped from small streams, some may be listed species that can't be used.
Exactly what I was waiting for.
Trapping or netting your own bait, from a lake or it's feeder creeks, SOMETIMES, just doesn't work.
Through the years, I've netted multiple baby bass, eyes, even northerns. I'm sure you guys have too!?
I've bought shiners up Erie, & had all of the above in my bucket.
Lesson learned,,,
We were down NC OBX. Tossing cast nets for mullet, glass minnows, whatever.
The MAN came along & checked everyones license & bait buckets. He said that the Wife & I were OK & moved on.
Then, he checked the residents fishing & netting mullet next to us & quickly had a SPANKY! We could easily hear them carry on, 50 yds away.
The warden went to his truck & started writing tickets.
Turns out, the older resident couple had 2 dead black bass fingerlings floating in their bucket of mullet.
After everything settled, they packed up to leave & told us that the fines & court costs will be close to $600!
'Protected species' out of season & DEAD, & they killed them.
SO,,, If 'SOMEONE' wants to be a major PITA about an out-of-season, or an 'invasive' species in your bait bucket,,,,,,,,,, ;>)
