Fig. 6From: Performance of a high-frequency (180 kHz) acoustic array for tracking juvenile Pacific salmon in the coastal oceanComparison of the statistical precision on survival estimates using two tag types. With identical survival estimates, the 95% confidence interval was 1.5x larger for the 180-kHz estimate relative to the 69-kHz estimate as a result of the reduced detection efficiency of the 180-kHz tags (76%) relative to the perfectly detected 69-kHz tagsBack to article page
