Young shrimp settle in estuarine salt marsh habitats during the juvenile phase of their life history, and processes that occur during their residency affect growth, survival, and recruitment of sub-adults to the fishery. We developed an agent based model that simulates the cumulative effects of temperature, salinity, and access to emergent marsh vegetation on juvenile brown shrimp growth and survival. Our model is spatially articulate, with three habitat types and three salinity zones it functions on an hourly time step to track growth and survival of shrimp super-individuals from recruitment into the shallow nursery habitats at 10 mm total length until they reach 70 mm and move into deeper bay water. We have compared our modeled shrimp production with various abundance and biomass data from fishery independent surveys. Preliminary analysis shows similarities in seasonal patterns, but annual variability in resource survey data appears higher than our modeled estimates. We are continuing to explore larval recruitment patterns and trophic interactions as possible interacting factors. Ultimately, we hope to use inter-annual variability in production estimates to reduce uncertainty in the current stock assessment model used by the US National Marine Fisheries Service. To better understand and forecast brown shrimp production in the northern Gulf of Mexico. underDevelopment Baumer, Tim J 409-766-3784 4700 Avenue U Galveston TX 77551 tim.baumer@noaa.gov Contact by email preferred. pointOfContact Leo, Jennifer 409-766-3500 4700 Avenue U Galveston TX jennifer.leo@noaa.gov custodian 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.

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.
