Fisheries Get Ready for a Close-Up
The CamTrawl and bottom-moored echosounders are being tested to improve stock assessment efforts in the North Pacific. The CamTrawl is a trawl-mounted stereo camera designed to identify species and determine size and density of animals as they pass by the camera during a haul. Scientists will share their work using the CamTrawl on research surveys and discuss results using bottom-moored, upward-looking echosounder systems. The echosounders have been observing walleye pollock as they gather to spawn in several Gulf of Alaska locations (Shelikof Strait, Resurrection Bay, Sanak Trough).
Session is moderated by retired commercial fisherman, Jay Stinson.
