Fig. 4From: Extent of predation bias present in migration survival and timing of Atlantic salmon smolt (Salmo salar) as suggested by a novel acoustic tagDistribution in timing from release to the first detection (top panel) and release to last detection (bottom panel) for tags within both the biased group (dark grey distribution) and the clean group to each array through the study site. Times to each array were calculated as cumulative time from release to arrays 66 km through 27 kmBack to article page
