Microdebris Abundance, Distribution, And Ingestion By Sargassum-Associated Juvenile Fishes In The Gulf Of Mexico, Olivia L. Lestrade, Frank Hernandez
Microdebris Abundance, Distribution, And Ingestion By Sargassum-Associated Juvenile Fishes In The Gulf Of Mexico, Olivia L. Lestrade, Frank Hernandez
Gulf and Caribbean Research
Holopelagic Sargassum is a critical nursery habitat for the early life stages of many marine fishes, including several federally managed species in the United States and Caribbean. Sargassum is often aggregated along surface convergence features where microdebris (synthetic, semi—synthetic, and naturally—derived particles size) have also been found in relatively high concentrations. In this study, we collected microdebris from Sargassum and adjacent open water habitats (in 2018), and juvenile fishes from Sargassum (in 2017 and 2018) in the northern Gulf of Mexico to quantify habitat—specific microdebris concentrations and the degree to which Sargassum—associated juvenile fishes ingest microdebris. Microdebris concentrations within …
Fishery Habitat In Estuaries Of The Gulf Of Mexico: Reflections On Geographical Variability In Salt Marsh Value And Function, Thomas J. Minello
Fishery Habitat In Estuaries Of The Gulf Of Mexico: Reflections On Geographical Variability In Salt Marsh Value And Function, Thomas J. Minello
Gulf and Caribbean Research
After 35 years working with many estuarine ecologists, I have concluded that all salt marshes are not created equal. This may seem like a trivial conclusion, but not everyone is a believer. While coastal salt marshes have many important ecological functions, their ability to support marine fisheries appears dependent on some specific characteristics. Extensive flooding of the marsh surface and a large amount of edge per area of vegetation have been identified as important in supporting production of juvenile brown shrimp (Farfantepenaeus aztecus), white shrimp (Litopenaeus setiferus), and blue crab (Callinectes sapidus). Data on other species are limited, but …
Spatial Biodiversity Patterns Of Fish Within The Aransas Bay Complex, Texas, Bridgette F. Froeschke, Megan M. Reese Robillard, Gregory W. Stunz
Spatial Biodiversity Patterns Of Fish Within The Aransas Bay Complex, Texas, Bridgette F. Froeschke, Megan M. Reese Robillard, Gregory W. Stunz
Gulf and Caribbean Research
The goal of this study was to consider the effects of habitat type and environmental conditions on the biodiversity of fishes within the Aransas Bay Complex, Texas and provide a management framework and an ecosystem examination of Essential Fish Habitat (EFH). A stratified, randomized experimental design was used to collect fishes from seagrass, oyster, and non-vegetated habitats within the Aransas Bay Complex from February through May 2010 over large spatial scales at the “bay-complex” level. We developed a biodiversity habitat model using Boosted Regression Trees (BRT). Fitted functions from the “best” fit BRT habitat model indicated that fish biodiversity was …
