The Great Lakes Fishery Commission (GLFC) Coordination Activities Program supported the purchase of a modern acoustic signal processing and data management system for ongoing, inter-agency fisheries acoustic surveys on Lake Erie. The new signal processing system, ECHOVIEW, is a product of the company SonarData. This project also supported ECHOVIEW training from the software developer for Messerís Einhouse and Witzel. We subsequently convened a workshop for members of the Lake Erie Forage Task Group to introduce ECHOVIEW software and its application to ongoing Lake Erie acoustic surveys.
