Composition of trawl catch fauna off the mouth of the Rio Baluarte, southeastern Gulf of California

From April to December 2007, experimental trawls (n = 44, 4 to 22 m depth) were made off the mouth of the Rio Baluarte ecosystem (MRB) and compared to experimental trawls (n = 54, 7 to 40 m) in the adjacent offshore region (AOR) from 2002 to 2007. For both ecosystems, a total of 143 species belongin...

Description
Summary:From April to December 2007, experimental trawls (n = 44, 4 to 22 m depth) were made off the mouth of the Rio Baluarte ecosystem (MRB) and compared to experimental trawls (n = 54, 7 to 40 m) in the adjacent offshore region (AOR) from 2002 to 2007. For both ecosystems, a total of 143 species belonging to 5 phyla were collected. Fishes comprised ca. 80% of the bycatch biomass, while molluscs and echinoderms contributed
