| Abstract: | The status of early-run chinook salmon Oncorhynchus tshawytscha of the Kenai River was assessed by coalescing information from creel surveys, inriver sonar project, educational harvests, inriver gillnetting project, and the Statewide Harvest Survey. In 1999, total return was an estimated 25,780 (SE = 370) chinook salmon, and spawning escapement was 17,276 (SE = 628) chinook salmon. In 2000, total return was 12,603 (SE = 234) and spawning escapement was 10,476 (SE = 329) chinook salmon. In 2001, total return was 16,874 (SE = 285) and spawning escapement was 14,075 (SE = 367) chinook salmon. After incorporating 1999-2001 estimates, return-per-spawner for the 1986-1995 brood years ranged from 0.53 (SE = 0.28) to 3.89 (SE = 0.71). Sibling ratios averaged 5.09 (SD = 2.54) for age 5 to age 4, 2.33 (SD = 1.26) for age 6 to age 5, and 0.07 (SD = 0.05) for age 7 to age 6 chinook salmon. |
