https://www.pangaea.de/ information publisher tableDigital This file contains data on polar cod (Boreogadus saida) used for stomach content analysis. The individuals caught from underneath the sea ice of the central Arctic Ocean during spring and summer. The fish were collected during Polarstern expeditions PS80 (2012), PS92 (2015), PS106.2 (2017) and PS122 (2019/2020). The data was collected to gain knowledge on the diet of polar cod and the ice-associated food web of the central Arctic. Fish parameters, such as length and weight, were recorded for 86 individuals. In addition, the condition index of the fish was calculated. The stomach and stomach contents were also weighed and the degree of digestion of the contents were estimated. completed Schaafsma, Fokje L
