Fig. 2From: Lab and field evaluation of tagging methods for the use of acoustic telemetry to observe sea urchin movement behaviour at ecologically relevant spatio-temporal scalesAcoustic telemetry array surrounding a salmon aquaculture site in Doctor’s Cove (NB, Canada). Receivers are shown as black triangles, urchin release points ‘a’ and ‘b’ are shown labelled in red, the extent of the salmon farm is shown as a polygon, and all detections of urchins during the study are shown as orange pointsBack to article page
