A Visual Feedback for Water-Flow Monitoring in Recirculating Aquaculture Systems

The optimal water flow in fish breeding tanks is one of the crucial elements necessary for well-being and proper growth fish, such as salmon or trout. Considering round uneven distribution water-flow velocity, ensuring a nearly an important task that may be performed using various sensors installed to monitor flow. Nevertheless, observing rapid development video analysis methods considering increasing availability relatively cheap cameras, use feedback has become interesting alternative limits number inside accordance with requirements breeders. In this paper, optical algorithms purpose estimation method based on their features proposed. results proposed are verified experimentally compared measurement obtained professional meter, demonstrating high correlation, exceeding 0.9, confirming solution good comparison expensive meters.
