Stomach contents of angler‐fish caught monthly throughout the year were examined. Stomach fullness data suggested that maximum feeding activity occurred during the autumn/winter period. Gadoids, in particular whiting and Norway pout, and also Nephrops were the main identifiable prey items. A wide range of other species contributed to the remainder of the diet. Size‐related differences in stomach contents were observed, Nephrops , cod and whiting being favoured by adult angler‐fish. Seasonal variability in the dietary occurrence of herring and Nephrops was noted, apparently related to differences in availability rather than selective feeding by angler‐fish.
