www.seadiscovery.com Marine Technology Reporter 33In May 2011, the automated salmon counting system utilizing BioSonics scientific sonar was deployed in a remote stretch of the Quinault River in Grays Harbor County, Washington. The system consists of 120 kHz split beam transducer and ROS PT 25 rotator mounted to an adjustable track trolley system custom fabricated from anodized aluminum. The track was gravity mounted with cement pier blocks for minimal bank disturbance and easydemobilization. A DT-X echosounder and control com- puter were housed in a mobile office trailer with a satellite modem for communication. The system operated for several months during which time, data was collected and processed for algorithm refinement and tuning for site- specific conditions. By the end of the deployment phase, the system was automatically transmitting daily salmoncount reports to project managers. BioSonics President Tim Acker expressed the significance of the project; ?This pilot stage deployment was monumental. To our knowl- edge, there is nothing else like this in the world. Completely autonomous, completely automatic fishcounting represents a shift in the way fisheries managers work. Imagine sitting at your desk and receiving a fish count report from an unmanned monitoring station twenty miles away.? About the Quinault Indian Nation The Quinault Indian Nation (QIN) consists of the Quinault and Queets tribes and descendants of five other affiliated tribes: Quileute, Hoh, Chehalis, Chinook, and Cowlitz.
