This is far off base from where this thread has gone, but......last summer we were at Random Lake, in Random, WI. A little girl had a cup with her goldfish from home in it, she was apparently going to let it go into the lake.

I was VERY happy to see a DNR guy stop her and her parents from releasing it! DNR guy told her father that if she let that go into this lake = There's a fine, can't remember how much,.....and they confiscate your vehicle,......and you're then banned from getting hunting/fishing license for some number of years,.....and can include jail time if person is 'multiple' offender or uncooperative! So, that's that! And I'm glad it's illegal to drop your kiddies' fish in the lake.
