Modeling Rockfish Habitat Suitability

Suitable habitats for different species of rockfish were determined by using the benthic terrain modeler in ArcGIS. Each species of rockfish has habitat preferences. For many species, substrate type is a major component in their niche.  Multibeam sonar imagery and sediment files from the USGS were analyzed to determine where different species of rockfish would be found. L3 Klein side scan sonar data obtained from the Ventura County Sheriff’s Department was overlaid on the USGS files to define the study area.

The coastal marine ecological classification system (CMECS) crosswalk tool and United States Geological Survey (USGS) sediment classification tools were used to interpret sediment types and create a raster surface. Fish species were match to substrate preferences and illustrated in the map legend. Developed models will be ground-truthed on a fishing expedition with Ventura Sportfishing. Students at Clark Magnet High School designed and built descending devices to safely release fish suffering from barotrauma, due to rapid decompression during ascent to the surface, back to the ocean. Any rockfish caught during the ground truthing operation will be released using the student created descending devices.
