Includes bibliographical references (pages 23-25). "Estimates of escapement were derived for the Campbell/Quinsam River system for 1994 using carcass tagging as part of the chinook key stream program. The Petersen estimate of chinook escapement was 2,982 in 1994 and includes hatchery removals (sales, broodstock, mortalities) and chinook passed over the hatchery fence. Males and females were mostly age 4, except in Campbell River where females were mostly age 5. Males and females were variable in age distribution. Females ranged from 37.8% age 4 in Campbell River to 68.6% age 4 in Quinsam Hatchery. Males ranged from 46.4% age 4 in Quinsam River to 71.4% age 4 in Campbell River. Estimated escapement of adipose-clipped chinook to the entire system was 182 in 1994. This estimate was further stratified by age, sex, and tag code. The total hatchery contribution (marked and unmarked) to the escapement was estimated by expanding the number of observed adipose clips by the adipose-clip mark rate at release. In 1994, the hatchery contribution was 69.8 % and 85:3 % for male and female chinook escapements, respectively. These hatchery contribution estimates were compared with those estimated using the Mark Recovery Program (Kuhn 1988) method of coded wire tag expansions. Using the MRP method, the total 1994 hatchery contribution was 64.0% for males and 83.2% for females"--Abstract, page viii. Includes abstracts in English and French.
