It is believed that the conformation of local topography, alternating saddles and highs, and the occurrence of coarse bioclastic sands sampled in the area might have activated the acceleration of bottom currents, suitable for the development of deep coral habitats. For coral reef fisheries, dynamite fishing and the use of poisons represent major threats in some parts of the world. googletag.pubads().setTargeting("cdo_ei", "trawling"); Definition of trawling in the Definitions.net dictionary.
