Proof of concept: visual categorization of carotenoid pigmentation in Arctic charr ( Salvelinus alpinus L) can predict stress response
Abstract Carotenoid pigmentation in Salvelinus alpinus has been connected to stress responsiveness in earlier studies. This has, however, only been tested with time‐consuming image analysis from photos. Here, we used quick visual categorization of carotenoid pigmentation to investigate the stress re...
