How accessible are disposal stations? I wonder how many backcountry folks have digital photo capability. You bring up a good point. Then, again, if you can figure out how to make them taste good, it makes sense to eat what you kill. (Bugs and vermin don’t count.)
The deer harvest in MD for 2011-2012 was more than 98,000 and every one of those was checked in. All you need to dispose of these finned vermin is a dumpster and bag of lime. If the angler wants to keep the fish for food, have the check-in agent remove the head rendering it unusable for a second bounty.
As to "back country folk"....think thay one over again FRiend.
