Description: Three replicates each of four different types of fish attraction structures and controls (15 sites total) were placed in 4.5 m of water in Chena Lake, a man-made, interior Alaska lake stocked with rainbow trout Oncorhynchus mykiss, coho salmon Oncorhynchus kisutch, Arctic char Salvelinus alpinus, Arctic grayling Thymallus arcticus, and chinook salmon Oncorhynchus tshawytscha. Artificial structures were placed into the lake in early June to allow for colonization by algae and macroinvertebrates and for fish acclimation. Counts of fish in a defined zone around the artificial structures and controls were made three times for each site by two divers stationed at defined points 2.5 m away from opposite corners of the artificial structures during early August. No fish were observed near any of the artificial structures or control sites during any of the counts. Fish were occasionally observed in less than 2 m of water in nearshore areas in the vicinity of the artificial structures.
