Editing Agulhas Current (section)

===Impact of rings===
[[Warm core ring]]s are known to have lower primary productivity than surrounding cold waters.  Agulhas Rings are no exception, and have been observed to carry waters with low [[Chlorophyll a|chlorophyll-a]] concentration water into the [[South Atlantic]]. The size of [[phytoplankton]] in Agulhas Rings tends to be smaller than in the surrounding water (around 20&nbsp;μm in diameter).<ref name="Mann" />

Agulhas Rings have also been observed as removing larval and juvenile fish from the continental shelf.  This removal of young fish can result in a reduced [[anchovy]] catch in the [[Benguela Current|Benguela]] system if a ring passes through the fishery.
