Abstract:

A two-year nekton data set was collected in fringing marshes with fyke nets and adjacent seagrass beds with trawls in five sampling sites along the northern Gulf of Mexico. Abundance of species within each site and on specific sampling dates is given. Three replicates were performed on each sampling date at each site, and samples were taken throughout the year. Sizes of C. sapidus (blue crab) was also recorded. This dataset includes data funded under NGI Y1.x122.045:0001.

Purpose:

Nekton collections from seagrass beds and marsh habitats were compared to elucidate the extent to which these two habitats are redundant in regards to the species they are able to support.

Abundance of Nekton -- Units indicate number of individuals caught in each collection. For sizes of C. sapidus, units are in millimeters.

Methods:

Fyke nets were deployed at fringing marshes to collect nekton with the receding tide and left for 24 hours. Trawls were used to collect nekton in seagrass beds when water was deep enough to accommodate a boat.
