Estuarine Living Marine Resources: Southeast Regional Distribution and Abundance (NCEI Accession 0163992)
This is the original (1991) Southeast regional component of NOAA's Estuarine Living Marine Resources (ELMR) Project, a national database of ecologically and economically important fishes and invertebrates in the Nation's estuaries. The distribution and relative abundance are depicted in a consistent format for 40 species of fishes and invertebrates, in 20 estuaries in coastal North Carolina, South Carolina, Georgia, and the east coast of Florida. Species were selected according to a set of criteria, which consider their commercial, recreational, and ecological value. For each species, five life stages are considered - adults, juveniles, larvae, spawning, and eggs - with some exceptions based on individual species life history. Each estuary is subdivided into one to three salinity zones (Tidal Fresh, Mixing, and Seawater). Relative abundance was ranked on a five-tier scale by month for each life stage of each species, in each salinity zone of each estuary. Details of the methods for the original Southeast ELMR component can be found in Nelson et al. (1991) and Nelson and Monaco (2000).

Supplemental Information | A data sheet was developed for each species in each estuary to facilitate the review and presentation of the information. Data compiled for each species/life stage included: (1) the salinity zone(s) it occupies (Tidal Fresh, Mixing, Seawater), (2) its temporal distribution in those zones by month (Jan-Dec), and (3) its relative abundance in those zones. Relative abundance values are ranked as 0 = not present, n = no information available, 2 = rare, 3 = common, 4 = abundant, and 5 = highly abundant. The abundance of a species life stage was considered relative to that of the same life stage of other "similar" species within a "guild", i.e. with similar life modes and sampling susceptibilities. These guilds are: Sessile Invertebrates, Shrimps and Squids, Large Crustaceans, Shallow Water Fishes, Pelagic Fishes, and Demersal Fishes. The draft relative abundance ranking were then verified through an extensive review process utilizing expert knowledge and field experiences of fisheries scientists, managers, and field biologists. The Southeast ELMR project was launched in 1987, and results published in 1991. For a complete description of the methods and results see Nelson et al. (1991) and Nelson and Monaco (2000). The quality and quantity of available data vary by species, life stage, and estuary. In general, data quality is best for well-studied, commercially- and recreationally-harvested species. Data quality regarding salinity zone boundaries may be affected by factors such as variations in freshwater inflow, wind, and tides. The qualitative nature of distributional data precludes statistical comparisons of species abundances. Data reliability was ranked using the following categories and criteria: (1) Highly certain: Substantial sampling data are available, and distribution, behavior, and preferred habitats are well documented within an estuary. (2) Moderately certain: Some sampling data are available for an estuary, and distribution, preferred habitat, and behavior are well documented in similar estuaries. 3) Reasonable inference: Little or no site sampling data are available, but information on distributions, ecology, and preferred habitats are documented in similar estuaries. These rankings of data reliability for each species and estuary are reported in the DATA_RELIABILITY column, and in Table 4 of the ELMR Southeast Report (Nelson et al. 1991).

Purpose | Estuaries are among the most productive natural systems and are important nursery areas that provide food, refuge from predation, and valuable habitat for many species. In spite of the well documented importance of estuaries to fishes and invertebrates, few consistent and comprehensive data bases exist that allow examinations of relationships between estuarine species found in or among groups of estuaries. In 1985, NOAA launched the Estuarine Living Marine Resources (ELMR) Project to develop a consistent database on the distribution, relative abundance, and life history characteristics of ecologically and economically important fishes and invertebrates in the Nation's estuaries. The project applied consistent data development methods to enable comparisons among species, specific life stages, and times of year within estuarine systems. The database is divided into five study regions: West Coast, Gulf of Mexico, Southeast, Mid-Atlantic, and North Atlantic. The Nationwide ELMR database now includes information for 153 species found in 122 estuaries and coastal bays. A series of reports have been published which summarize the methods and results of the ELMR Program. These include a National report (2000), regional data summary reports for the North Atlantic (1994), Mid-Atlantic (1994), Southeast (1991), Gulf of Mexico (1992), and West Coast (1990), and regional life history summary reports for the West Coast (1991) and Gulf of Mexico (1997). Copies of these reports are available free upon request, and some are available as pdf. |
