Abstract

Organic pollution in the Havana coastline is affecting octocorals assemblages, and little is known about its effect on the growth rate (GR). A fixed belt transect (250 x 2 m) was used to locate the colonies. The GR of Eunicea flexuosa and Plexaura kuekenthali was significantly higher in the reef with more organic pollution (3,6 cm/año y 4,1 cm/año, respectively) vs. reference sites, which seems to be related to their heterotrophy.
