Assessing the link between ontogenetic shifts in gill raker and diet composition of Arctic cod (Boreogadus saida) in the Canadian Beaufort Sea-Amundsen Gulf

Included herein are the data files used in the above study that links gill raker density in Arctic cod (Boreogadus saida) to diet and habitat preferences. There are three (3) datasets. The first lists the diet items observed in the stomachs of the sampled Arctic cod from the Beaufort Sea (sampled in 2019) - (ACdietitem_2024.csv). The second lists individual fish sizes and their gill raker numbers and density, along with the size of the items found in individual stomachs (AC_size_gr_dietsize.csv). Finally, the third dataset is the data that lists most of the other data as well, but also includes the Stable Isotope data of carbon (C), nitrogen (N), and sulfur (S), which are used in both traditional and Bayesian ellipse analyses. The data can be re-analysed using the scripts available on GitHub at: (to be determined).
