| Trophic patterns for Greenland Halibut are reported for the first time in the Canadian Beaufort Sea and Amundsen Gulf (n = 269). Samples were collected from 2012 to 2014 on the upper (300–500 m) and lower continental slope (750–1500 m) and were analyzed for stomach contents, stable isotopes ratios and fatty acids (FA). Stomach contents indicated that Arctic Cod, Boreogadus saida, was the main prey ingested on the upper slope (50–94% of total biomass) whereas Gelatinous Snailfish (Liparis fabricii) and Zoarcids (Lycodes spp.) dominated diets on the lower slope (17–62% of total biomass). Stable isotope mixing models and FA analyses also identified benthopelagic fishes (i.e., Liparis spp., B. saida) as key prey and highlighted large dietary overlap among... |
