OAR 635-100-0190
Lower Columbia River Coho Fishery Management

(1)

The mortality rate limit for wild coho salmon caught in Columbia River fisheries shall be set annually prior to the time these fisheries open. This limit shall not exceed the level specified in Table 1 of this rule corresponding with the observed parental escapement, expressed as a fraction of full seeding, and the index of marine survival for the upcoming adult coho return.

(2)

For the purpose of implementing the management strategy described in paragraph (1) of this rule the following definitions apply:

(a)

Parental escapement means the number of wild fish in the spawning population, expressed as a fraction of full seeding, that were the parents of the upcoming wild coho return;

(b)

Marine survival index means a forecast of ocean survival for 3-year old coho returning in the upcoming year based upon the number of 2-year old hatchery coho (jacks) observed the previous year divided by the number of hatchery smolts released in the spring of the same year the jacks returned;

(c)

Full seeding means the number of wild coho in a natural spawning population that is sufficient to produce maximum production of subsequent juvenile smolt offspring;

(A)

Pending further revision, full seeding for the Clackamas population means 3,800 wild adult coho as counted passing North Fork Dam;

(B)

Pending further revision, full seeding for the Sandy population means 1,340 wild adult coho as counted passing Marmot Dam.

(3)

Wild coho populations in the Clackamas and Sandy basins shall serve as the index stocks for the purposes of setting annual fishery mortality rate limits.

(4)

In those circumstances when ODFW deems the expected mortality of lower Columbia River wild coho in upcoming ocean fisheries is too high for conservation purposes, ODFW shall actively negotiate through the Pacific Fishery Management Council (PFMC) for regulations that yield a lower fishery mortality rate.

(5)

Achievement of fishery management strategies described in this rule is contingent on continuation of fishing regulations and fish marking programs that minimize the impact on wild fish through selective fishing methods and the manipulation of fishing season time and location. In addition, ODFW shall continue to explore new methods to further reduce the mortality of wild fish in all fisheries.
