Use of inverted echosounders to monitor the migration timing and abundance of juvenile salmon in the Discovery Islands, British Columbia / S. Rousseau ... [et al.]. : Fs97-6/3227E-PDF

“In this study, the authors evaluate the use of inverted, bottom mounted echosounders to monitor juvenile salmon migration timing and distribution in the Discovery Islands and Johnstone Strait, which constitutes a key area in terms of understanding juvenile salmon mortality during their passage from lower British Columbia rivers to the Pacific ocean. The authors further suggest that moored inverted echosounders can provide insightful data on the behaviour, abundance and migration timing of juvenile salmon and prove to be a non-invasive, cost-effective approach for long-term monitoring purposes”--Introd., p. 1.
