Species composition (fishes and macroinvertebrates), abundance, biomass and lengths are reported, along with salinity, temperature and dissolved oxygen data. Data are in spreadsheet format. To establish a baseline of fish and macroinvertebrate abundance at two restored (LHA, LHB) and four natural (LHC, WPH1, WPH2, PS7) marshes at various distances from a freshwater diversion in the vicinity of West Pointe a la Hache, Louisiana. Little is known about how river diversions influence the ecological trajectory, food web structure, and function of natural versus created marshes. To address this gap, this project established sites in the West Point a la Hache (WPH) area (Barataria Bay, in Plaquemines Parish, Louisiana), near the WPH siphon which periodically shunts Mississippi River water into the local marshes. Sites were also established in nearby marshes that were restored as part of the Lake Hermitage Marsh Creation Project, representing an ideal model system to examine how seasonal and spatial shifts in salinity due to river diversions influence species composition and food web structure in both natural and different-aged created marshes. Objectives of the overall project included characterizing species compositions and abundances in multiple trophic levels (microbes to upper trophic level predators) and applying bulk (SIA) and compound-specific stable isotope analysis (CSIA) of amino acids (AA) in producer and consumer tissues to describe and compare the structure and complexity of food webs and reveal aspects of fish residency.
