JUVENILE LIFE HISTORY AND AGE COMPOSITION OF MATURE FALL CHINOOK SALMON RETURNING TO THE KLAMATH RIVER, by Cornelius M.

Based on trap efficiencies, we calculated that 1, chinook emigrated past the trap site during the study period. Chinook abundance index calculated for the same time period wasKlamath River mainstem seining was.

We discuss the methods used to estimate recruitment for fall-run Chinook salmon, Oncorhynchus tshawytscha, populations for the Stanislaus, Tuolumne, and Merced rivers in the San Joaquin River Basin (SJRB).

We identify data sets of accurate escapement and Age 2 abundance estimates for the Stanislaus and Merced Rivers from to and.

The Klamath Basin fall Chinook run estimate is the 5th lowest in the 39 year record, and 43% of the year average. The adult Chinook returns to the basin were % percent of the projected forecast(18, pre vs. 31, post). The adult fall Chinook natural escapement conservation threshold of 40, was not managed for or met this season.

Most years, anywhere f toadult fall-run salmon lay and fertilize their eggs in the Klamath. In the fall ofthough, a total of 17, adult fish are estimated to have spawned — the lowest return on record.

Federal fisheries officials said Tuesday they will consider putting the Klamath River's once-flourishing wild spring-run chinook salmon on the list of threatened or endangered species.

The National Marine Fisheries Services plans a month review on whether to give protected status to the salmon in and around the Klamath River.
