Vertical migration of Northern krill

  Northern krill (Meganyctiphanes norvegica) are euphausiid crustaceans widely distributed around the North Atlantic from Canada to Scandinavia and from the Arctic to the Mediterranean. As consumers of plankton and as prey to a variety of mammals, birds and fish species they form an important link in the oceanic food web. They undertake extensive diurnal vertical migrations, moving into deep water during the daytime and into shallower water at night. This project investigates the effect of light on the swimming behaviour of individual krill and examines the underlying causes of the observed migration patterns.
