In that screen shot it refers to a WAC starting with 232-. All those are outdated and if you look them up leads you to nowhere.
Here is a link to the relevant law:
http://apps.leg.wa.gov/wac/default.aspx?cite=220-440-070Last part of it being the most relevant to this thread.
"(5) Animals taken with the use of a body-gripping trap may not be retained and must be disposed as conditioned in the special trapping permit or as specified in WAC 220-440-090. Raw fur may only be retained for personal use or educational purposes which do not result in retail sale or commerce."
So maybe you are going to use cage traps and you are wondering, can I keep the fur if I am a WCO or if I am using cages?
Her you go, have a look.
http://apps.leg.wa.gov/wac/default.aspx?cite=220-440-110Applicable part:
"(2) WCOs with a valid trapping license may retain raw fur of wildlife taken using a special trapping permit, for personal use or educational purposes that does not result in retail sale or commerce. The carcass must be disposed of in a lawful manner according to WAC 220-440-090"
It doesn't seem to address animals caught in cage traps however in WAC 220-440-090 it says " Wildlife taken under this chapter remains the property of the state and may be disposed of in the manner and under the conditions that follow:"
No allowance is made for retaining them for use in that chapter.
I doubt though anyone is likely to be ticketed for a cage caught animal kept where legally taken though. I negotiated the wording in the law with Department staff and I guess my fault if there is poor language. I had thought it was fixed so legal to keep cage caught stuff but apparently not quite.
