Includes bibliographical references (page 12). "Adult and juvenile coho migrations were monitored at Zolzap Creek, British Columbia, as part of the 1995-1996 Nisga'a Aboriginal Fisheries Strategy. Smolt trapping was conducted from mid-April to mid-June using an in-stream wire-mesh fence. A total of 12,557 coho smolts were captured during the trapping period, and an unknown number migrated out during periods when the fence was not Operational. Of those captured, 10,156 were released with coded-wire tags. Migration timing, mean length and weight at age, and age composition are presented. Adult coho escapement was monitored using an in-stream fence and carcass surveys. The counting fence was operational between 5 September and 6 December. A total of 908 adult coho were counted at the fence. Adipose-clip rate was 34.0% for-adult coho. Age and length characteristics of adult males and females are presented. Canadian and US commercial harvests were examined using coded-wire tag recovery data obtained from the Mark-Recovery Program. Total commercial exploitation rate on Zolzap Creek coho in 1995 was 67.7% (12.9% Canadian, 54.8% US). Of the total commercial catch of Zolzap Creek coho, Canadian catch accounted for 19.0% and the US catch accounted for an estimated 81.0%. Harvests occurred over a wide area ranging from Canadian Statistical Area 6 (Butedale) to the Northern Outside Statistical Area in Alaska (northwest of Juneau, AK). Canadian harvests were largest in Statistical Area 3 for both the net and troll fisheries. US harvests were confined entirely to Alaska with largest in the Southern Inside Statistical Area for the net fishery and the Central Outside Statistical Area for the troll fishery. Total survival was 3.6% and smolt-to-spawner survival was 1.0%"--Abstract, page vii. Includes abstracts in English and French. Coho salmon British Columbia. Escapement (Fisheries) British Columbia.
