Not specifically.
You don't need a LTCF to transport an unloaded long gun with unloaded magazines and ammo kept in a separate container, to and from your hunting area or target range without stops. You need no paperwork whatsoever to purchase a firearm.
And if you're fishing with a gun, you're doing it wrong.
Per statute, you do not need any reason to get a LTCF other than wanting it. Whatever else extra they ask at the sheriff is not a statutory requirement.
