The research areas consisted of two control (unmanaged) marshes and two impounded (managed) marshes managed areas were surrounded by levees with water-control structures constructed by the U.S. Department of Interior, National Biological Survey. We conclude that the restricted water exchange in marshes under structural marsh management diminishes recruitment and standing stocks of species that must migrate from coastal spawning sites to marsh nurseries. Even when water-control structures were open, the densities of these transient species were low inside managed areas. In contrast to the negative effect of management on transient species, the resident fish and crustacean populations seemed to flourish in the managed areas when a drawdown was not in effect. Following two months of a drawdown, however, the populations of residents appeared similar inside and outside managed areas. Increases in submerged aquatic vegetation (SAV) within ponds occurred outside the managed areas during the study period, but not inside managed areas. Because many resident species were closely associated with the SAV, the effect of management on SAV may have been responsible for the distribution patterns of resident species. The purpose of this study was to test the effects of structural marsh management on habitat use by fishery species and other nekton before and after a spring drawdown of managed areas. underDevelopment 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 asNeeded 1-m2 throw trap 1.14-m diameter cylindrical drop trap Farfantepenaeus aztecus Farfantepenaeus duorarum Litopenaeus setiferus abundance brown shrimp crabs distribution estuarine dependent fish invertebrates macrofauna marsh management nekton pink shrimp salt salt marsh submerged aquatic vegetation white shrimp theme 1995 temporal Gulf Of Mexico Louisiana 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.

Entered data were checked against field data sheets to minimize entry errors. Samples were processed in the laboratory. After samples were sorted, and specimens identified and measured, information was entered into an Excel spreadsheet or DBF file, and printed out. Quality control was provided by comparing entered data against the specimen identification (ID) sheet by one biologist reading from the ID sheet and a second biologist checking the data print-out. Corrections were made at this time, saved, and a back-up copy made. Hard copies of the files were then printed, and provided to the Principal Investigator. A print-out was also stored in the project folder along with the original field and laboratory data sheets.
