| Abstract: |
This dataset contains abundance, mass, length, sex and species composition of the on-marsh nekton community in restored (LHA, LHB) and natural (LHC, WPH1, WPH2, PS7) marshes at various distances from a freshwater diversion in the vicinity of West Pointe a la Hache, Lake Hermitage, and Port Sulphur, Louisiana in May 2018 and May 2019. Minnow traps (wire mesh traps) were deployed at three sub-habitat locations (edge, creeks, ponds) at each site. Taxonomic identification of individuals was determined to the lowest possible taxonomic level. Salinity and temperature data for each sample location are also included in this dataset. Data are in spreadsheet format. |

Methods: Three minnow traps (A,B,C) were deployed at three sub-habitat locations (creek, edge, pond) at six sites (LHA, LHB, LHC, WPH1, WPH2, PS7) for three consecutive days in May 2018 and May 2019. Traps were allowed to soak for 1-2 hours at a time, after which all organisms collected were identified, counted, and measured (length and weight). In 2018 PS7 was sampled four times, while all other sites were sampled three times. In that year, the first PS7 sampling occurred in the afternoon, after which samples were collected during morning hours, consistent with sampling at all other sites. In 2019 new site waypoints were generated at LHB Edge 2, LHC Creek 1, LHC Creek 2, LHC Creek 3, LHC Edge 1, LHC Edge 2, LHC Edge 3, LHC Pond 1, LHC Pond 2, LHC Pond 3, WPH1 Creek 2, WPH1 Creek 3, WPH1 Edge 1, WPH1 Edge 2, WPH1 Edge 3, WPH1 Pond 1and WPH1 Pond 3. |
