P. and T. J. Minello. 2015. Small-Scale Nekton Density and Growth Patterns Across a Saltmarsh Landscape in Barataria Bay, Louisiana. Estuaries and Coasts 38(6): 2000-2018. Nekton in the northern Gulf of Mexico often depend on marsh habitat and estuarine nursery areas during their life history, but patterns of habitat use and the underlying processes that drive these patterns are not fully understood. We examined small-scale (1-50 m) patterns of habitat use in Barataria Bay, Louisiana, between 2002 and 2006 by collecting nekton with a 1-m2 drop sampler. Habitat-specific densities were estimated for six habitat types at various distances from the shoreline into the marsh (Marsh1M = 1m and Marsh3M = 3 m into the marsh) and over shallow nonvegetated bottom, SNB (SNB1M = 1 m, SNB5M = 5 m, SNB20M = 20 m, and SNB50M = 50 m) seaward of the marsh. Habitat-specific growth rates also were estimated for brown shrimp Farfantepenaeus aztecus caged in SNB1M, SNB5M, and SNB20M. Nekton density patterns in Barataria Bay appeared to be clearly different from the Galveston Bay model, which predicts nekton distribution patterns relative to the marsh shoreline. Although densities in Barataria Bay were significantly higher in samples near the marsh shoreline (Marsh1M or SNB1M) for brown shrimp, blue crab, and white shrimp, highest mean densities were not always present in marsh edge vegetation. In addition, densities of brown shrimp and white shrimp in Barataria Bay declined much more steeply with distance into the marsh than in the model. Daily growth rates (1.0 - 1.2 mm TL day-1; 68 - 89 mg day-1) for brown shrimp were similar among SNB habitat types. Our results suggest that SNB in Barataria Bay may be relatively more important as habitat for fishery species than previously assumed. The purpose of this study was to examine the small-scale (1-50 m) patterns of nekton distribution in lower Barataria Bay and test the generality of the Galveston Bay model of habitat-specific nekton densities. completed Baumer, Tim J 409-766-3784 4700 Avenue U Galveston TX 77551 tim.baumer@noaa.gov Contact by email preferred. pointOfContact Rozas, Lawrence P Contact by email preferred. custodian Penaeus aztecus theme World Register of Marine Species (WoRMS) OCEAN > ATLANTIC OCEAN > NORTH ATLANTIC OCEAN > GULF OF AMERICA place Global Change Master Directory (GCMD) Location Keywords 20.8 ANIMALS - INDIVIDUAL - MASS theme NODC DATA TYPES Coastal Waters Of Louisiana place NODC SEA AREA NAMES Nekton density patterns brown shrimp habitat use theme 2005-2006 temporal Barataria Bay Gulf of Mexico place DOC/NOAA/NMFS/SEFSC > Southeast Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

After sample collection, field data were entered into an Excel spreadsheet or database file (DBF) using database manager software. A text file was created to describe these data and associated variables. Entered data were checked against the field sheets by two biologists to minimize entry errors. Samples were processed in the laboratory, sorted, specimens identified and measured, and information was entered into an Excel spreadsheet or DBF file. Files were printed out and compared against original data sheets by two biologists for data entry errors. Corrections were made at this time, the electronic file was saved, and a back-up copy made. Hard copies of the QCd files were printed and stored in the project folder along with the original field and laboratory data sheets. The electronic file was also sorted and examined by the Lab Supervisor or other project personnel in a variety of ways to look for outliers, missing data, and other potential errors. Verified data files were then saved electronically on the Galveston Laboratory server and backed-up as needed. otherRestrictions otherRestrictions Access Constraints: None | Use Constraints: Please cite appropriately American Optical Temperature-Compensated Refractometer Refractometer A lightweight, handheld optical instrument that measures metalworking fluid concentration.
