Multi-disciplinary fingerprints reveal the harvest location of cod Gadus morhua in the northeast Atlantic.

The article presents a study which classifies the fingerprint of a harvest location of individual cod Gadus Morhua L. in the northeast Atlantic. The study used a combined approach to classification, such as otolith microchemistry, otolith shape analysis, and body morphometry, which found more powerful than any single technique. It also determined that based on binomial and multinomial logistic regression analyses, cod from widely separated origins were classified with high placement success. It noted that focusing on the placement of individual fish, the study represents a decisive advance toward identifying fish harvested from protected populations.
