Is it legal to catch game fish and use them as sturgeon bait?

In Idaho, you can use fish and fish parts for bait anywhere except in "no bait" waters. Many anglers use dead rainbow trout or trout parts from hatcheries for sturgeon bait, but they need a receipt to show the source if they have more than six trout in their possession. If other species of gamefish are used, anglers need to watch limits for them as well.
