Gymnodinium Brown Tide in the Magellanic Fjords, Southern Chile
In April 1999, a brown tide was recorded in the Magellanic fjords, Southern Chile. The causative taxa were two unidentified morphs of Gymnodinium that resemble Gymnodinium mikimotoi Miyake et Kominami ex Oda. Although there were many reports from fishermen about water discolorations along the region...
