Barataria Bay 2005-2006

Metadata Updated: November 1, 2023

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.
