Scientific Collection Permits
As specified in WAC 220-20-045 and RCW 77-32-240, it is unlawful to collect foodfish, shellfish, or wildlife or their nests and/or eggs for the purpose of research or display without first obtaining a Washington state scientific collection permit.
State scientific collection permits are issued to scientists/researchers, educators/educational institutions, and museums, aquariums/zoos. They are NOT issued to the general public for collection/take of fish and/or wildlife.

Then I clicked on the first rule.
(b) "Display" means to place or locate fish, shellfish, wildlife, or the nests of birds, so that public viewing is allowed.

I'm not putting these fish on public display.
It's my understanding that you cant sell or buy native species, you can't open an aquarium exhibit for people to come see, but if I catch one and put it in my personal fish tank for my own personal enjoyment then it's fine.
If you can find that rule on that nanfa site please post a link.
