Species Richness of Demersal Fish
Species richness of demersal fish was calculated for NMFS fish trawls (shelf and slope) conducted at depths between 50 and 1280 meters. The mean number of fish species recorded for trawls (± standard deviation) was 16±5. Species richness results are displayed for individual trawls, as well as mean richness for 5' grid cells. There appear to be three trawl areas with consistently high species richness: NW of Point Año Nuevo, SW of Morro Bay, and near the center of Cordell Bank NMS. In addition, there are smaller clusters within all three national marine sanctuaries. This map can be used to identify hot spots of demersal fish biodiversity.
