Field studies to characterize the alongshore epifauna (shrimp, crabs, echinoderms, and small fishes) along the western shore of southern Biscayne Bay were started in 2005 and then expanded in 2007 as part of the monitoring program of the Comprehensive Everglades Restoration Program (CERP). Species abundance indices (occurrence and density) and community metrics (diversity and other) were examined and followed over time. Relationships to salinity were explored and, as the time series lengthened, Habitat Suitabiity Indices (HSI) in relation to salinity and submerged aquatic vegetation (SAV) could be developed. In 2012, the alongshore epifauna project became integrated three other projects in IBBEAM (Integrated Biscayne Bay Ecological Assessment and Monitoring) and continues to provide feedback for CERP on the effects of CERP project implementations in an adaptive management process. Most recently IBBEAM is monitoring the effects of advance implementations of the Biscayne Bay Coastal Wetlands Project, a component of CERP.

This data set contains sensitive biological resource data for anadromous fish species in the Bristol Bay Subarea. The Subarea includes marine and coastal areas of Bristol Bay and part of the southern Alaska Peninsula. (This area extends from directly south of Goodnews Bay to slightly north of Port Seniavan along the Bristol Bay side of the Alaska Peninsula, as well as the Pacific Ocean side of the Alaska Peninsula from Cape Providence to Kupreanof Peninsula.) Vector lines in this data set represent species occurrences in rivers and streams. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for the Bristol Bay Subarea. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the FISH (Fish Polygons) data layer, part of the larger Bristol Bay Subarea ESI database, for additional fish information.

Juvenile spotted seatrout and other sportfish are being monitored annually over a 6-mo period in Florida Bay to assess their abundance over time relative to restoration of a more natural pattern of freshwater flow from the Florida Everglades through implementation of the Comprehensive Everglades Restoration Plan (CERP). This monitoring and assessment project will provide a scientific basis for the selection of spatial and temporal abundance indices, performance measures, and targets to determine the effect of CERP on Florida Bay resources. Monitoring annually during the period of greatest abundance, May through October, will provide data to determine whether there is a significant relationship of sport fish distribution and abundance to salinity and other environmental variables. Habitat suitability models will be developed from the data and will be used to predict distribution and abundance under different scenarios of freshwater inflow, past and future. This data set provides information on stomach contents of juvenile spotted seatrout. This dataset also contains the data on potential prey species (caridean and penaeid shrimps and small fishes) caught in the trawl at a subset of stations sampled.

The toxicity of sediments in Biscayne Bay and many adjoining tributaries was determined as part of a bioeffects assessments program managed by NOAA's National Status and Trends Program. Biscayne Bay was selected by NOAA for this survey because data from the NSandT Mussel Watch Program and data from previous surveys of the bay had shown a potential for toxicity and other adverse biological effects. In addition, no bay-wide information had been generated on the toxicological condition of the bay sediments and several agencies had indicated a need for this type of data and a willingness to assist NOAA in collecting them. The study area was defined as extending from Dumbfoundling Bay at the north end to Little Card Sound at the south end, seaward to the barrier islands or reef, and landward to the shoreline or saltwater control structures. This area was determined to encompass a total of 484 kilometers of the sea floor. During 1995 and 1996, 226 samples were collected from randomly-chosen locations and tested for toxicity and analyzed for chemical concentrations. Data from these tests and analyses are included in the report. Samples for benthic community analyses were collected at one-third of the stations; however, data from those analyses are not included in the report but are available from NOAA's online database http://nbi.noaa.gov/data/. The survey was designed to characterize sediment quality throughout the greater Biscayne Bay area. Surficial sediment samples were collected during 1995 and 1996 from 226 randomly-chosen locations throughout nine major regions. Laboratory toxicity tests were performed as indicators of potential ecotoxicological effects in sediments. A battery of tests was performed to generate information from different phases (components) of the sediments. Tests were selected to represent a range in toxicological endpoints from acute to chronic sublethal responses. Toxicological tests were conducted to measure: reduced survival of adult amphipods exposed to solid-phase sediments; impaired fertilization success and abnormal morphological development in gametes and embryos, respectively, of sea urchins exposed to pore waters; reduced metabolic activity of a marine bioluminescent bacteria exposed to organic solvent extracts; induction of a cytochrome P-450 reporter gene system in exposures to solvent extracts; and reduced reproductive success in marine copepods exposed to solid-phase sediments.

Between May 5, 1993 and September 19, 1994, we collected quantitative 1-m2 area drop samples and measured a variety of habitat attributes using field surveys and aerial photography to characterize three existing marshes (Atkinson Island, Hog Island, and Cedar Point) in Galveston Bay. We also compared nekton densities among different types of intertidal and shallow subtidal habitats (pond, channel, cove, open bay, and four marsh types). The vegetated surface consistently contained more species and dominant species exhibited at least some degree of habitat selection. To maximize fishery habitat, we recommend placing greater emphasis on constructing low marsh edge habitat by creating large areas of Spartina alterniflora and Scirpus maritimus marsh interspersed with a dense network of shallow channels and interconnected ponds.

Seagrasses are highly productive ecosystems. A before-after-control-impact (BACI) design was used to examine effects of dredging on seagrasses and the animals that inhabit them. The control site North Biscayne Bay (NBB) and impacted site Port of Miami (POM) had seagrass densities decreased during the before, Fish and Invertebrate Assessment Network (FIAN) 2006-2011 and after, Faunal Monitoring Due to Harbor Dredging (FMHD) 2014-2016 studies. Turbidity levels increased at NBB and POM basins during the FMHD study, especially in 2016. Animal populations decreased significantly in NBB and POM in the FMHD study compared to the FIAN study. If seagrass communities are not stabilized, animal numbers will likely continue to decrease. There could be impacts on several fisheries vital to the South Florida economy. Additional research could determine if animal populations and seagrass densities have rebounded or continued to decrease.
