Polar cod is an important part of the food web of the Arctic. Sarah Maes (KU Leuven) and Fokje Schaafsma (Wageningen Marine Research) investigated the diet of polar cod from the Barents Sea, with the help of colleagues from the KU Leuven and the Alfred Wegener Institute. They did this by combining traditional microscopy with DNA analysis. The study resulted in new insights regarding the diet of polar cod which are now published in the journal Marine Ecology Progress Series.
