30677 Data Set Published / External 3954 Galveston Fisheries Ecology Projects Project Completed Study compared nekton densities and community composition in a natural mixed seagrass bed dominated by Halodule wrightii (shoalgrass) with those found in three shoalgrass transplant sites and adjoining sand habitats in western Galveston Bay, Texas, USA. Communities were monitored for 36 months (1994-1997) post-transplant. Total densities of fishes, decapods, annelids, benthic crustaceans, and most dominant species were significantly higher in natural seagrass than in transplanted shoalgrass or sand habitats during most sampling periods. Taxonomic comparison of community compositions indicated that nekton and benthos communities in natural seagrass beds were usually distinct from those in transplanted beds or sand habitats, which were not significantly different. Provided transplants persist, re-establishing a shoalgrass bed that resembles a natural seagrass bed and its faunal communities in the Galveston Bay system will take longer than 3 years. Identify and describe the relationship between fishery productivity and the coastal environment.

Zip 85K Zip Chked Viruses Inapp Content Quality control was provided by comparing field data sheets and specimen identification (ID) sheets against the entered data print-out. One biologist read from the field data or specimen ID sheet while a second biologist checked the data entry print-out. Corrections were made at this time and saved. The project data manager also examined these corrected data, and sorted these data in a variety of ways to look for outliers, missing information, and other potential errors. No 0 Yes Yes No 365 This data is currently wavered under the current NOAA guidelines for relational databases. To Be Determined 0 The data resides on a secure government network requiring multi-factor authentication for network access. 1 After sample collection, laboratory and field data were entered into an Excel spreadsheet or data base file (DBF) using database manager software and a text file was created to describe these data and associated variables. 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. 53086 Document 53087 Entity 53090 Entity 53088 Entity 53089 Entity 53091 Entity gov.noaa.nmfs.inport:30677 Carlos Rivero 2016-02-11T06:54:12 SysAdmin InPortAdmin 2026-03-04T19:17:18 2021-10-21 Southeast Fisheries Science Center SEFSC 75 Virginia Beach Drive Miami FL 33149 USA (305)361-5761 www.sefsc.noaa.gov 8:00 a.m. - 4:30 p.m. EST 1001 Public No No 2021-10-21 1 Year 2022-10-21
