Something does not seem right here. The first thing that popped into my head is that maybe F&W stopped somebody coming off the ice that had illegal fish and they convincied the F&W that somebody was doing something illegal.
If you have one empty beer can and F&W see this that is probable cause to search. A bloody fillet knife or fish guts again probable cause. You do have the right to ask what they are searching for when they want to check a vehicle. Just my thoughts
