Paul, That would be highly illegal here in Wisconsin.dumped in the water
I rigged up my Xtracycle to carry all of my spearfishing gear and bought a cooler that fits into the side bag. I mainly shoot crappie, perch, and bluegill so a smaller cooler is all that's needed. On occasion we do put the hurt on the local carp population and it's during those times that a buddy brings his pick-up so that we can drag them away to his farm. I've eaten smoked carp, but our lakes are so full of them we could never eat them all and they have the same contamination issues that you have.
Here's a couple of pics.
