Description: Mark-recapture experiments conducted during the summer of 1993 were used to estimate abundance of Arctic char Salvelinus alpinus near the Agulowak and Agulukpak rivers within the Wood River lake system, Alaska. Estimated abundance of char at the Agulowak River was 5,441 fish (95% CI 4,993 to 5,950). This is substantially less than the estimated historic average of over 11,700 fish. Abundance estimates at the Agulukpak River ranged between 4,011 and 7,118 char, which brackets the estimated historic average of over 6,300 fish. Size composition at the Agulowak River was similar to that observed in 1976-1979, suggesting the mechanism causing the decline acted on all segments of the population. Size distribution of Arctic char at the Agulukpak River was slightly lower than those sampled in 1976-1978. Based on these results the Department of Fish and Game, Division of Sport Fish recommends reducing the bag limit for Arctic char at the Agulowak River and limiting terminal tackle to single-hook artificial lures only.
