The Food Consumed by Shags and Cormorants around the Shores of Cornwall (England)

188 Shags and 27 Cormorants, which had been feeding around the shores of Cornwall and whose stomachs contained identifiable food organisms, have been examined. 2. The Shags were found to have been feeding principally upon Sand Eels (Ammodytes spp.), and other non-marketable fishes. 3. The proportion of flatfishes and other economic species which had been devoured by the Shags was negligible.
