Chirolophis snyderi has been assessed as Data Deficient. While this species has a broad geographic range, it is found in shallow near-shore waters where it may have been impacted by a range of threats. Further research is needed on possible threats, and population trends before a more accurate assessment of conservation status can be made.
|Range Description:||Chirolophis snyderi is distributed from the Chukchi Sea and the western Gulf of Alaska to the Sea of Okhotsk, Tatar Strait, and the Pacific coast of Hokkaido.|
The depth range for this species is likely to be 0 - 70 m. The record of 490 m is likely to be a result of a previous specimen from a shallower tow (Sheiko pers. comm. 2008).
Native:Japan; Russian Federation; United States (Alaska)
|FAO Marine Fishing Areas:|

|Population:||Chirolophis snyderi is a rare species.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Chirolophis snyderi is a demersal species that has a depth range of 0 - 70 m in nearshore waters (Mecklenburg and Sheiko 2004) over soft and rocky bottoms.|
|Major Threat(s):||It is unknown what major threat processes are impacting this species. Chirolophis snyderi may be taken as by-catch in the Sea of Okhotsk fisheries. In 1995 the total catch of Russian fishing fleets in the Sea of Okhotsk was 4.3 million metric tons (Stokke 2001). Due to the coastal nature of this species it may be impacted by coastal development and pollution. The Sea of Okhotsk has been heavily impacted by heavy shipping due to bilge and ballast water, fuel and oil leaks, and anti-fouling chemicals.|
There are no species-specific conservation measures in place for Chirolophis snyderi, however its distribution range does coincide with a number of marine protected areas.
Further research on the population trends and threats for this species is needed.
