Three replicates of mid-water, floating fish attraction devices (FADs) were placed into Harding Lake, a 1,000 ha interior Alaskan lake stocked with; Arctic char Salvelinus alpinus, lake trout Salvelinus namaycush, Arctic grayling Thymallus arcticus, and rainbow trout Oncorhynchus mykiss, and containing natural stocks of burbot Lota lota, least cisco Coregonus sardinella, and northern pike Esox lucius. Replicates of benthic brush pile FADs were placed at three sites in Hidden Lake, a 7.2 ha interior Alaskan lake stocked with rainbow trout, Arctic grayling, and Arctic char. Three equivalent control sites were established and marked in each lake. Timed counts of fish in a defined zone around the FADs and controls were made in random order three times for each site during early, middle, and late summer. Counts were made by two divers stationed at defined points 2.5 m away from opposite corners of the FADs. Almost no fish were observed in Harding Lake at either the FADs or at the control sites. Fish were observed and counted in Hidden Lake during mid-summer and fall, but numbers observed were not significantly different between FADs and control sites.
