ABSTRACT: Deep-sea corals and sponges thrive between 45-500 meters depth in
the cold, upwelling waters and complex benthic topography of the Southern
California Bight (SCB). Corals and sponges are vulnerable to bottom-contact
fishing, so there is a need to understand the spatial overlap of commercial
fishing activities with these deep-water coral habitats. This study
characterized fishing intensity, marine debris, corals, and sponges on 25
deep-water banks in SCB. Fishing intensity was estimated using commercial
fisheries landings (2007-2011) from California Department of Fish and Game
with observations of marine debris, corals, and sponges in images from 350
remotely operate vehicle dives conducted by NOAA since 2003. Survey sites
were ranked using a novel algorithm that weighs richness, abundance,
frequency, and fishing intensity (RAFFi) to prioritize sites for
conservation. Priorities were compared to protections offered by existing
essential fish habitat (EFH) and other marine protected areas in Southern
