Summer habitat use of Arctic char ( Salvelinus alpinus ) in a small Arctic lake, monitored by acoustic telemetry
Abstract – Acoustic technologies were applied to describe how landlocked Arctic char from Iqalugaajuruluit Lake, Baffin Island, interact with its lacustrine habitat. Acoustic data from the lake bottom was collected using sonar equipment and substrate types were verified with benthic grabs and mapped...
