Grounds are located where warm and
cold currents converge, where warm and cold currents meet happens to have
regular foggy conditions, as the overlying warm and cold air come in contact
with each other. They also tend to have high biological productivity, because
plankton growth is encourage by the mixing of warm and cold currents. Some of
the world's most productive fishing.
