Excerpt from Distribution and Abundance of Fishes and Invertebrates in North Atlantic Estuaries: May 1994
The objective of the elmr program is to develop a consistent data base on the presence, distribution, relative abundance, and life history characteristics of ecologically and economically important fishes and invertebrates in the nation's estuaries. The data base is divided into five study regions (figure 1) and con tains the monthly relative abundance of each species' life stage by estuary for three salinity zones (seawater, mixing, and tidal fresh) identified in noaa's National Estuarine Inventory (nei) Data atlas-volume I and supplement (ncaa The nationwide data base contains information for 135 fish and invertebrate spe cies found in 122 estuaries.
Only a few sampling programs Massachusetts Division of Marine Fisheries, Maine Department of Marine Resources inshore trawl surveys) collect fishes and invertebrates with identical methods across groups of estuaries within a region (howe et al. 1991, mdmr Therefore, most existing estuarine fisheries data cannot be compared among estuaries because of the variable sampling strategies. In addition, existing research programs do not focus on how groups of estuaries may be important for regional fishery man agement, and few compile information for species having little or no economic value.
