When the theory was tested in a 115 - square - mile area of the Southern Ocean, tiny
crustacean zooplankton ate up all the phytoplankton.
Scientists did not count on the phytoplankton, stimulated by the dumped iron, being eaten by tiny
crustacean zooplankton.
However, the scientists from India's National Institute of Oceanography (NIO) and Germany's Alfred Wegener Institute (AWI) did not count on these phytoplankton being eaten by tiny
crustacean zooplankton.
In a paper just published in the Journal of Plankton Research, two Canadian marine scientists, Sonia Batten and James Gower, reported evidence of a critical intervening step — a growth spurt in just the right kind of tiny animals,
crustacean zooplankton, that young salmon thrive on.
These include Arctic cod and capelin, while krill and Calanus finmarchicus are replaced by Arctic amphipoda (another group of
crustacean zooplankton), which live on ice algae which are also absent from Atlantic water.
The researchers conducted a six - week experiment manipulating the presence of sunfish and water temperature using two non-native and native

The up to one millimetre long

The abundance of some
zooplankton (i.e. microscopic
crustaceans in the water that eat algae) was lower at higher salt concentrations, but not low enough to cause a bloom of algae.
They feed mainly on small shrimp - like
