Model for evaluating seabirds preferences for hake offal in Patagonia

This data set was used to build a model to evaluate the seabirds' preferences for hake offal derived from an artisanal fishery in Patagonia.

Main results are: The fishers' main contribution to seabirds is through offering them the offal of hake catches. We observed that seabirds consumed hake liver 99% of the time, while they consumed stomach less frequently (24%). We identified that southern giant petrels and black-browed albatrosses consumed more liver, while kelp gulls ate more stomach. The liver comprises 51.6% fat, essential for high trophic level marine predators such as black-browed albatrosses.
