The Icelandic marine ecosystem contains large stocks of zooplankton such as calanoid copepods and krill, which are eaten by adult herring and capelin, adolescents of numerous other fish species, and by baleen whales.
These four species of planktivorous fish feed mainly on calanoid copepods and larger crustaceans, the latter predominantly hyperiid amphipods to the north and euphausiids to the south.
Although the zooplankton database is small, it suggests that growth rates of calanoid copepods and other crustaceans are dependent on temperature such that the time from hatching to the next adult generation is shorter in warmer water.
There are only 80 species of euphausiids, 50 of chaetognaths, about 40 of pteropods and less than 2000 for the most diverse group, the calanoid copepods.
In the pelagic ecosystem off Greenland the population dynamics of calanoid copepods and to some extent krill play a key role in the food web, being a direct link to fish stocks, baleen whales, and some important seabirds, such as little auk (Alle alle) and Brünnich’s guillemot (Uria lomvia).
Aethia pusilla), which specialize on calanoid copepods, have a narrow foraging niche
