Includes bibliographical references (pages 23-24). "Estimates of escapement were derived for the Campbell/Quinsam rivers system for 1986-1988 using carcass tagging as part of the chinook key stream program. The Petersen carcass tagging estimate of chinook escapement was 7,298 in 1986; 8,295 in 1987 and 13,750 in 1988. A second Petersen estimate of 18,073 chinook was derived in 1988 using live tagging. Males were predominantly age 4 and 5 while females were predominantly age 5. Escapement estimates are presented by river, sex, and age. Escapements of adipose clipped chinook to the entire system were 1,902 in 1986; 1,830 in 1987 and 1,325 in 1988. These estimates are further stratified by age, sex and tag code. The total hatchery contribution to the escapements was estimated using coded wire tagged/adipose mark rates at release. In 1986, the hatchery contributed 59.0 % of the male chinook escapement and 60.2 % of the female escapement. In 1987 these contributions rose to 80.0 % and 68.4 % for male and female chinook escapements, respectively. The hatchery contribution increased further, in 1988, to 83.7 % for males and 89.3 % for females"--Abstract, page x. Includes abstracts in English and French.
