About the Species
Eulachon are an anadromous (moving between freshwater and saltwater) smelt in the family Osmeridae. The binomial species name is derived from Greek roots; thaleia meaning rich, ichthys meaning fish, and pacificus meaning of the Pacific.
Eulachon are found from northern California to southwest Alaska. The southern distinct population segment (DPS) is listed as threatened under the Endangered Species Act.
Eulachon have many other names—smelt, hooligan, oolichan, and fathom fish. First Nations people called eulachon "salvation" fish because the return of spawning runs to coastal rivers meant the difference between life and starvation after a hard winter. Native people continue to fish for eulachon by traditional methods for use as an important subsistence food and medicine.
Adult eulachon typically spawn at age 2-5 years in the lower portions of rivers. Many rivers within the range of eulachon have consistent yearly spawning runs; however, eulachon may appear in other rivers only on an irregular or occasional basis. The spawning migration usually occurs between December and June.
NOAA Fisheries is committed to conserving and protecting eulachon. Our scientists and partners use a variety of innovative techniques to study, learn more about, and protect this species.

NOAA Fisheries listed the southern DPS of Pacific eulachon as threatened under the ESA in 2010 and designated critical habitat in 2011.
Though the designation applies only to eulachon, this critical habitat will provide benefits to other listed species, including salmon, steelhead, bull trout, and green sturgeon.
The designation covers 16 creeks and rivers within Washington, Oregon, and California. The total number of stream miles included in this designation is 335 (539 km). The Federal Register notice has information describing specific creeks and rivers (including latitude and longitude identifiers) and maps of the areas designated.
The ESA gives the Secretary of Commerce discretion to exclude areas from designation if he determines that the benefits of exclusion outweigh the benefits of designation. We have excluded areas that overlap with Native American tribal lands. These areas are excluded because of the unique trust relationship between tribes and the federal government, the federal emphasis on respect for tribal sovereignty and self-governance, and the importance of tribal participation in numerous activities aimed at conserving eulachon. These exclusions consist of portions of the Klamath, Quinault, and Elwha Rivers in California and Washington.

- An economics report describing how we estimated the economic impact of this proposal on different areas: Economic Analysis of Critical Habitat for the Southern Distinct Population Segment of Eulachon (PDF, 103 pages).
- A report describing how we weighed the benefits of exclusion versus the benefits of designation, to recommend the exclusion of particular areas: Designation of Critical Habitat for the Southern Distinct Population Segment of Eulachon: Section 4(b)(2) Report (PDF, 42 pages).
