FIGURE 44.—Location of nearshore transects used to study habitat use of juvenile Chinook salmon in Lake Quinault, 2004. 73
FIGURE 45.—Photos of large woody debris habitat (upper photo) and emergent vegetation habitat (lower photo) of Lake Quinault. We compared day and night Chinook salmon counts with a sign rank test. The abundance of fish at each site was calculated two separate ways; 1) nearshore abundance (number of fish per 100 m of shoreline), and 2) shoreline density (number of fish per m 2 ). The nearshore abundance is the estimated number of fish to 1-m depth and is based on fish counts along one or two transects (depending on the bottom slope) and then expanded based on the distance from the shoreline to 1-m depth. The shoreline density is the number of fish along the 0.4-m transect. We used a transect width of 2.5 m for the 0.4 contour depth and 2 m for the 0.7- 74
