Description
Summary:Euchœta norvegica has been found to be an important constituent of the food of the American pollack (Willey, 1921), and Bigelow (1926) expresses the opinion that it may form an important part of the food of mackerel and herring in the Gulf of Maine. In Loch Fyne in the Clyde sea-area, where Euchœta occurs in abundance at certain times of the year, it has never been found in the stomachs of herring (Scott, 1907). This is surprising for, as Scott remarks, Euchœta is “rich in oily matter, and apparently is of as much value as Calanus for herring food.” Macdonald (1927), however, has found that adult Meganyctiphanes norvegica feed on Euchœta , so, indirectly at least, it contributes to the food of the herring.
