Crawdad Regulations

I would like someone to clarify for me the exact regulations on fishing for crawdad/crayfish in Idaho. My understanding is that you only need a regular fishing licence unless you have over five(5) traps. And that if you have over five traps then you need some type of commercial licence. Also to my understanding, there is no number limit or size restrictions on crawdad in Idaho. Is all that I have said correct and are there any other regulations? Also, how much does one of those commercial licences cost?


Trapping or Seining Minnows and Crayfish
Nongame fish (minnows), yellow perch, and crayfish may be taken only in waters open to fishing; provided the seine or net does not exceed ten (10) feet in length or width, and nets and seines must have three-eighths (3/8) inch square or smaller mesh; and the minnow or crayfish trap does not exceed two (2) feet in length, width or height. If the trap is of irregular dimension, but its volume does not exceed the volume of an eight (8) cubic foot trap, it is also legal to use. Nets and seines may not be left unattended. Traps must be checked at least every forty-eight (48) hours.
All traps must have a tag attached bearing the owner’s name and address.
All game fish (except yellow perch) and protected nongame fish incidentally taken while trapping or seining must
be immediately released alive. All fish so taken must immediately be killed except where stated otherwise. Crayfish
may be kept alive to be used as bait only on the water where captured. Nongame fish and crayfish may only be taken
during the season set for the taking of game fish in those waters.
Only five (5) crayfish traps can be fished with a valid fishing license. If more than five traps are used at one time, you must obtain a Commercial Fishing License and trap tags. A resident Commercial Fishing license is $111.75 and must be obtained from IDFG headquarters or a Region office. 
It is illegal to destroy, disturb, or remove any traps belonging to others.
