Abstract
Evaluating flatfish activity can be a useful tool for studying fish behavior and welfare. The aim of this workwas to obtain a quantitative index for measuring flatfish activity using image analysis. Accordingly, motor activity of a sole population was recorded by digital video for three nights, bearing in mind the nocturnal lifestyle of the species. Subsequent image analysis was done by image subtraction of consecutive frames. The result was a ‘‘difference frame’’ showing the changes in ...
