In the North Atlantic, they prey on euphausiids in the genera "Meganyctiphanes", "Thysanoessa" and "Nyctiphanes" and small schooling fish (e.g. the genera "Clupea", "Mallotus", and "Ammodytes"). Of the 1,609 fin whale stomachs examined at the Hvalfjörður whaling station in southwestern Iceland from 1967 to 1989 (caught between June and September), 96% contained only krill, 2.5% krill and fish, 0.8% some fish remains, 0.7% capelin ("M. villosus"), and 0.1% sandeel (family Ammodytidae); a small proportion of (mainly juvenile) blue whiting ("Micromesistius poutassou") were also found. Of the krill sampled between 1979 and 1989, the vast majority (over 99%) was northern krill ("Meganyctiphanes norvegica"); only one stomach contained "Thysanoessa longicaudata". Off West Greenland, 75% of the fin whales caught between July and October had consumed krill (family Euphausiidae), 17% capelin ("Mallotus") and 8% sand lance ("Ammodytes sp."). Off eastern Newfoundland, they chiefly feed on capelin, but also take small quantities of euphausiids (mostly "T. raschii" and "T. inermis"). In the Ligurian-Corsican-Provençal Basin in the Mediterranean Sea they make dives as deep as to feed on the euphausiid "Meganyctiphanes norvegica", while off the island of Lampedusa, between Tunisia and Sicily, they have been observed in mid-winter feeding on surface swarms of the small euphausiid "Nyctiphanes couchi".
