On the Grand Newfoundland Bank and Flemish Cap boreal the forms inhabiting the sub-Arctic water masses are predominant. The boreal forms are supplemented with a small amount of Arctic forms entering this area by the North Atlantic current. However, in the shallow waters of the Grand Newfoundland Bank the oceanic forms are inferior to the neretic ones. It is in the boreal zone that zooplankton is the most abundant. The waters of the North Atlantic current are considerably poorer than the sub-Arctic waters, which the zone of horizontal transformation, i.e. the zone of intermingling of the boreal and warm water fauna, is the poorest. The zooplankton distribution usually follows the conventional pattern within a year. However, in autumn many stations in the boreal zone are frequented by warm water forms which leave the area in spring. The food zooplankton biomass becomes less abundant throughout the area investigated. The great bulk of zooplankton is represented by boreal fauna and, in the main, by Calanus finmarchicus, the development and distribution of which governs the yield of the region concerned.
