Bill, actually it is illegal in Minnesota to cull fish from your live-well to replace with others in our state of Minnesota. We can keep fish alive in a live-well on the water, when we remove the boat from the water, we must then drain it.
Minnows transported from one BOW to another must be done so with fresh bottled or tap water we bring with us. My brother had a long discussion with a boat ramp representative from the state as he was doing just that. But try to prove the water in your cooler was fresh and brought from home while standing at the boat ramp, after you've dumped your bait from the bait bucket into it.
Also, one small caveat to the law of transporting live fish, as I understand. It is legal for a person under 16 years of age to do so, for an aquarium, but a limit of only 4 per species.
