Mean value and error bars for relative (a) T. libellula, (b) Euphausidae, and (c) Teleostei abundance for polar cod from Billefjorden, Rijpfjorden, and Smeerenburg. The mean relative abundance of prey x in prey‐specific stomachs focuses strictly on stomachs containing prey x. Letters above mean value points indicate statistically significant difference from indicated site/season (F = Fall, W = Winter, s = Smeerenburg, r = Rijpfjorden, b = Billefjorden), *p < .005 and **p  < .001 (Kruskal–Wallis test)
