The main objective of this project was to assess variability among estuaries in supporting fishery species and other abundant nekton. The project is part of a larger effort of the National Marine Fisheries Service Galveston Laboratory to develop a Comparative Assessment of Gulf Estuarine Systems (CAGES). The nekton abundance data summarized in this report are available at https://data.gcoos.org. This cooperative study with state natural resources agencies was designed to use fishery independent monitoring data and compare historical catches from 4.9-m and 6.1-m trawl surveys. This report provides an assessment of the abundance, length frequencies, and biomass of 14 species of fish and four species of decapod crustaceans that were either abundant in the samples or economically important. The most abundant species in the analysis include bay anchovy, Atlantic croaker, spot, and brown shrimp. Other fishery species of particular interest include Gulf menhaden, white shrimp, pink shrimp, blue crab, spotted seatrout, southern flounder, and red drum. While the years analyzed varied among states, samples from most estuaries were available and analyzed for the years 1986 to 2005. The 24 estuaries analyzed were identified using the Estuarine and Coastal Drainage Areas delineated by the U. S.Geological Survey and listed in NOAAs Coastal Assessment Framework The authors would like to thank the field crews who collected the data and the biologists who analyzed the samples at Texas Parks and Wildlife Department, Louisiana Department of Wildlife and Fisheries, University of Southern Mississippi, Gulf Coast Research Laboratory and Florida Fish and Wildlife Conservation Commission. We would like to thank Phil Caldwell of the NOAA Galveston Lab for his assistance with GIS and construction of figures. We also would like to thank Michael Harden, Harry Blanchet, and Marty Bourgeois at the LDWF for their assistance with the Louisiana data. Chris Stafford and Kerry Flaherty at FFWCC provided assistance in compiling the Florida Data and Harriet Perry at FFWCC provided valuable guidance.
