Canadian Stock Assessment Secretariat research document, 1480-4883 ; 99/208 Includes bibliographical references (p. 21-22). Optimal production of adult chinook salmon from the Stikine River was investigated with information from a stock assessment program (1975-1997) and catch sampling programs on the Canadian inriver commercial and aboriginal gillnet fisheries and on the U.S. marine commercial gillnet and recreational fisheries. Stock assessment was based on aerial surveys, mark-recapture experiments to estimate abundance of large (mostly age 1.3 and older) salmon over the spawning grounds, a weir over the Little Tahltan River, and a radiotelemetry study to determine distribution of spawning salmon. Considering that estimated spawning abundance has been above 17,368 large chinook salmon since 1986 (excluding 1995), it was concluded that this population has probably recovered from overfishing incurred in the 1970's. It is recommend that annual aerial surveys be suspended, a coded-wire tag program to estimate marine harvests and smolt abundance be reinstated, and that there be a continuation of the current stock assessment program based on catch sampling, escapement sampling, the mark-recapture experiment, and the weir on the Little Tahltan River. gccst Fisheries resources gccst Salt water fish gccst Fishing area gccst Fisheries management Bernard, David R.
