| Notes | "Although the pattern of abundance and tag/recovery data during the period of supplementation indicated that Alsea River hatchery fish returned as adults to Winchester Dam in some numbers, it is apparent that 15 years of hatchery releases did not result in a viable, self-sustaining population of naturally spawning fish. The unresolved issue is, What do the few remaining anadromous O. clarki represent: remnants of the original Umpqua River gene pool, descendants of the Alsea River hatchery fish, or a mixed lineage? The run-timing shift suggested that an indigenous component may remain." (from the Abstract) This publication discusses the issues surrounding a possible listing of Umpqua River sea-run cutthroat trout. The species was listed as endangered in August, 1996. |
