    • Fish assemblages in southern California using trawl data from the National Marine Fisheries Service

    Metadata Updated: May 22, 2025

    Fish benthic trawls were completed by the National Marine Fisheries Service Groundfish Survey Program (NMFS GSP). Data from 477 fishery independent trawls ranging from 55-1200 m in depth were collected June-November in 1977, 1989, 1992, 1995, and 1997- 2002. Fish that were not present in at least 5% of the trawls were removed from this analysis, resulting in a dataset containing information on 59 fish species. Site groups were calculated using the Bray-Curtis dissimilarity coefficient with average means clustering (Romesburg, 1991). Gear included a 7.6-m head-rope semi balloon otter trawl with 1.25 cm codend mesh trawled for 5-10 minutes at each station.
