"Estimates of escapement were derived for the Campbell/Quinsam rivers system for 1991 using carcass tagging as part of the chinook key stream program. The Petersen estimate of chinook escapement was 8012 in 1991. Both males and females were predominantly age 4 and 5 but the specific age structure varied between the Campbell River, Quinsam River and Quinsam Hatchery. Escapement estimates are presented by river, sex, and age. Escapement of adipose-clipped chinook to the entire system was 278 in 1991. 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 1991 the hatchery contribution was 71.1% and 66.7% 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 hatchery contribution was 66.1% for males and 63.6% for females in 1991"--Abstract, page vii. Includes abstracts in English and French.
