NOAA's Estuarine Living l\/larine Resources Program 



The Strategic Environmental Assessments (SEA) Division of NOAA's Office of Ocean Resources Conservation 

 and Assessment (ORCA) was created in response to the need for comprehensive information on the effects of 

 human activities on the Nation's coastal ocean. The SEA Division performs assessments of the estuarine and 

 coastal environments and of the resources of the U.S. Exclusive Economic Zone. 



In June 1985, NOAA began a program to develop a comprehensive data base on the life history, relative 

 abundance, and distribution of fishes and invertebrates in estuaries throughout the Nation (Monaco 1 986). The 

 Estuarine Living Marine Resources (ELMR) program has been conducted jointly by the SEA Division, the National 

 Marine Fisheries Service (NMFS), and other agencies and institutions. The Nationwide ELMR data base was 

 completed in January 1994, and includes data for 135 species found in 122 estuaries and coastal embayments. 

 Seven reports and reprints are now available free upon request, and two others are scheduled for completion in 

 1994 (see below). This report, Distribution and Abundance of Fishes and Invertebrates in Mid-Atlantic Estuaries, 

 summarizes information on the distribution and abundance of 61 fish and invertebrate species in 22 Mid-Atlantic 

 estuaries. A National report summarizing the data and results from the program will be published in 1995. 



Three salinity zones, as defined in Volume 1 of NOAA's National Estuarine Inventory Data Atlas (NOAA 1 985), 

 provided the spatial framework for organizing information on species distribution and abundance within each 

 estuary. These salinity zones are tidal fresh (0.0 to 0.5 ppt), mixing (0.5 to 25 ppt), and seawater (>25 ppt). The 

 primary data developed for each species include spatial distribution by salinity zone, temporal distribution by 

 month, and relative abundance by life stage, e.g., adult, spawning, juvenile, larva, and egg.
