3 $aDuring April 13 - June 19, 1992 a weir was operated at the outlet of Buskin Lake to estimate abundance, growth, length distribution, survival, age composition, and run timing of Dolly Varden Salvelinus malma. Of a total of 74,451 Dolly Varden that emigrated through the weir, 7,202 were tagged and 284 were recaptured from previous tagging efforts. A total of 3,422 Dolly Varden were counted emigrating through a weir on the stream running from Lake Louise to the Buskin River. The dominant age class in the 1992 emigration was age 5. Survival estimates from recaptures at the weir ranged from a low of 6.3% from 1990 to 1991 to a high of 18.5% from 1989 to 1990. The Jolly-Seber estimate of survival from 1990 to 1991 was 29.3%. The Jolly- Seber abundance estimate for 1991 was 60,585 compared to the weir count of 30,725. American River estimates of abundance for both Jolly-Seber and Petersen methods for 1989 and 1990 were not significantly different.
