Schooling fish such as herring or capelin can be seen and quantified from the air. ASL Borstad’s CASI multispectral imager surveys large areas over a short period of time, providing a snapshot of school distribution and sizes. Our custom software provides quantitative estimates of school sizes that can be used for stock assessment.
