Feed waste results in increased production costs to the cage fish farming industry and produces negative environmental impacts. A computerized system, consisting of digital scanning sonar and current meter, was developed for monitoring, assessment, and optimization of the fish feeding process. The system can detect and monitor quantity and direction of wasted food pellets and also predict the t...
