Regulations require min. size 3¼" from tip of rostrum (nose) to tip of tail.
There is only one native crayfish species in Washington – the Signal crayfish (Pacifastacus leniusculus). This species can be identified by its
uniform brownish coloration, white or light coloration of the claw joint ,and the smooth surface of its carapace and claws compared to that of
nonnative species. Native crayfish are the only crayfish that may be removed from the vicinity of the waterbody alive. If you cannot
positively identify your catch as a nonnative species, the daily limit and other restrictions listed above for native crayfish apply.
