ABALONE

All Areas Pinto Closed Surveys show a continued decline in numbers of all size abalone. The closure is necessary to allow recovery of stocks. Abalone have been listed as an endangered species.

CLAMS, OTHER THAN RAZOR CLAMS

Always check the local biotoxin status before harvesting via the biotoxin hotline (1-800-562-5632) or www.doh.wa.gov/shellfishsafety.htm. Biotoxins can present hazards in any clam species, and butter and varnish clams can retain elevated levels of biotoxins for extended periods. Clams can be dug by hand or hand-operated fork, pick, rake, or shovel. Each digger must use a separate container. Digging equipment may be shared. Clam holes must be refilled. To reduce clam mortality, please push any undersized clams into the refilled hole. See year-round harvest closures and advisories on Shellfish Safety Information and area closures on Marine Preserves, Conservation Areas & Shellfish Protection Zones.

CRAYFISH (crawfish)

All Open Waters Native Species
(Signal Crayfish)
1st Mon. in May-Oct. 31 Min. size 3¼” from tip of rostrum (nose) to tip of tail. Daily limit 10 lbs in shell. All females with eggs or young attached must be immediately returned to the water unharmed. No Shellfish/Seaweed license is required. See gear rules on  Statewide Gear Rules.
Nonnative Species 1st Mon. in May-Oct. 31 Must be kept in a separate container. Must be dead before being removed from riparian area (immediate vicinity of water body). No daily limit, size, or sex restrictions. No Shellfish/Seaweed license is required. See Statewide Gear Rules.
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.

How to humanely kill and preserve crayfish: There are two important steps to killing a crayfish quickly and humanely. The first is to chill them in ice or ice slurry for 20-30 minutes, and the second is to pierce their head with a knife.
