Distribution and Abundance of Fishes and Invertebrates in Mid-Atlantic Estuaries Introduction Rationale This report presents information on the spatial and temporaldistribution, and relative abundance of 61 fish and invertebrate species in 22 estuaries along the Atlantic coast from Virginia to Massachusetts. Its purpose is to disseminate data developed in the Na- tional Oceanic and Atmospheric Administration's (NOAA) Estuarine Living Marine Resources (ELMR) program (inside front cover). The ELMR program is conducted by the Biogeographic Characterization Branch of the Strategic Environmental Assessments (SEA) Division, in cooperation with regional research institutions (Figure 1). The presence, distribution, and relative abundance of each species and the time period it utilizes each estuary are the primary data compiled. The data and framework presented in this report are illustrative of the nationwide ELMR program. The objective of the ELMR program is to develop a consistent data base on the distribution, abundance, and life history characteristics of important fishes and invertebrates in the Nation's estuaries. The Nation- wide data base is divided into five study regions (Figure 1). The data base contains the monthly relative abun- dance of each species' life stage by estuary for three salinity zones (seawater, mixing, and tidal fresh) iden- tified in NOAA's National Estuarine Inventory (NEI) Data Atlas-Volume I (NOAA 1985). The Nationwide data base contains information for 135 fish and inver- tebrate species found in 122 estuaries. Estuaries are among the most productive natural sys- tems and are important nursery areas that provide food, refuge from predation, and val
