| Abstract: | Beginning August 15, 1993, commercial set gill net and purse seine catches from selected waters along the southwest side of Kodiak Island were sampled for the incidental harvest of steelhead trout Oncorhynchus mykiss. The total estimated incidental commercial catch of steelhead from waters included in the Karluk study area, between August 15 and August 31, was 58 fish. A total of 21 steelhead were harvested for personal use and 17 were released from the set gill net fishery. Set gill net and purse seine fisheries harvested and sold an estimated five and 15 steelhead, respectively. Sport and subsistence fisheries harvested an estimated 189 and 382 steelhead, respectively. The estimated abundance of spawning steelhead for the entire Karluk River drainage in the spring of 1994 was 9,116 fish (SE = 522). The majority of the spawning population was composed of initial spawners (81%), followed by repeat (18%) and multi-repeat (1%) spawners. Mean length for female initial and repeat spawners was 644 mm and 703 mm, respectively; and 588 mm and 671 mm, respectively for males. Multi-repeat spawning males and females had mean lengths of 789 mm and 720 mm, respectively. Mean length for all spawning steelhead was 627 mm. Estimated spawning survival of steelhead was 51%. Spawning survival for females was 43% and 51% for males. Survival of male steelhead by spawning histories was 54% for initial spawners and 22% for repeat spawners; for females survival was 46% for initial spawners and 40% for repeat spawners. No multi-repeat spawning steelhead were observed during the recapture event. |
