Abstract:

We examined the effects of a hydrologically restrictive transportation corridor on the nursery use of various habitats in the Mobile-Tensaw River delta (MTD). We compared nekton assemblage structure in fall 2009 and spring 2010 among 3 locations and 3 major habitat types (marsh, submerged aquatic vegetation SAV dominated by Vallisneria americana, and shallow non-vegetated bottom SNB) commonly found throughout the MTD using 1 m2 drop samplers. Sample locations (Tensaw River: TR, Chocolatta Bay: CB, and Below Causeway: BC) were selected based on their degree of tidal connectivity with the wider estuary (TR CB BC). Nekton assemblages varied among locations and habitat types. Recruitment by the young of transient fishery species appeared to drive the nekton assemblage structure at the least hydrologically restricted locations (BC and TR) in the delta, whereas estuarine-resident species dominated the nekton assemblage at CB. Species richness was greater at BC than at CB. Within locations, mean densities of abundant species were concentrated in SAV and marsh. Delta locations directly connected to Mobile Bay, therefore, likely provide an important nursery for fishery species such as white shrimp, blue crab, gulf menhaden, and southern flounder. Additional studies will be needed, however, to determine whether these fishery species represent strong conduits for cross ecosystem transfer of energy and nutrients between the delta and northern Gulf of Mexico.

Purpose:

The purpose of this study was to examine the effect of a hydrologically restrictive transportation corridor on the nekton composition and use of potential nursery areas of the Mobile-Tensaw River delta.

Data Quality

Quality Control Procedures Employed:

Each sample was assigned a unique identification code. Field collected samples were tagged redundantly (e.g. one label inside of the collection vessel and a matching label attached to the outside of the vessel). The identifier and its associated information (e.g. date, location, habitat) was recorded on field data sheets. Once a sample arrived at the laboratory, the label remained with the sample throughout the various stages of sample processing. After data were entered into an Excel spreadsheet or similar database file, the information was printed out and compared against the field data sheets by two biologists. Corrections were made at this time and saved. 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.

Process Steps

Process Step 1

CC ID: 284651
Description:

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.
