This study developed a method to measure and characterize discolouration patterns observed in the fillets of yellowtail flounder (Limanda ferruginea) on the east coast of Canada.
- •
An image processing program was developed to analyse fillet discolouration patterns for left and right fillets, including the size and location of bruising.
- •
Estimates of bruise area ranged from 0 to 124.5 cm2, with a mean of 12.1 cm2, and accounted for an average of 4.3% of fillet area.
- •
Bruises were not uniformly distributed on any of the fillet sides. Results revealed a strong tendency for bruising to occur at the anterior dorsal region of the fillet, commonly known as the “nape”.
