Description: During the period 3 July to 16 August 1993, abundance, composition, and selected fishery statistics were estimated for Dolly Varden Salvelinus malma (Walbaum) on the Anchor River. A total of 8,262 Dolly Varden were counted through a weir located 1.5 km upstream from salt water on the Anchor River. This Dolly Varden immigration is the lowest total adult return documented since this study was begun in 1987, however, the spawner component of this return increased slightly from the previous year. Dolly Varden behavior in the intertidal waters downstream of the weir structure appeared to have changed from previous years. Dolly Varden were not observed in traditional holding areas prior to migrating upstream through the weir structure. This behavioral change coincided with unseasonably warm stream water conditions and is suspected of having a negative influence on Dolly Varden catch rates by anglers in the intertidal area.
