This file represents salmonid freshwater and estuarine Essential Fish Habitat (EFH) in the western United States. Congress, through the Magnuson-Stevens Act, defined EFH as "those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity." This dataset follows the federal codification of delineating EFH using 4th field Hydrologic Units. It spatially depicts designated EFH for Federally-managed Pacific salmon within freshwater and estuarine regions of California, Oregon, Washington, and Idaho. Areas above identified certain impassible dams are not designated EFH, and these have been removed from the 4th field Hydrologic Units. Only areas defined as EFH are present in this dataset. Each Hydrologic Unit polygon has been coded to indicate for which species of salmon (Chinook salmon, coho and/or pink) it represents EFH.

This data set contains sensitive biological resource data for reef, marine, estuarine, and native stream fish species in coastal Hawaii. Vector polygons in this data set represent fish distribution. 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 Hawaii. 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 FISHPT (Fish Points) data layer, part of the larger Hawaii ESI database, for additional fish information.

To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, reef fish assessment surveys are conducted as part of Rapid Ecological Assessments (REA) during Pacific Reef Assessment and Monitoring Program (Pacific RAMP) cruises in the Main Hawaiian Islands region by the NOAA Pacific Islands Fisheries Science Center (PIFSC). REA is a useful method for gathering data pertaining to ecologically significant biological components of a reef habitat over small spatial scales. Because the method provides a quick "snapshot" of major reef biota during a single dive or snorkel survey, it is particularly useful in assessing remote areas that are only rarely visited and where little time can be spent. Surveys are conducted along a set of transect lines. With their high level of taxonomic resolution over small spatial scales, REAs are a good complement to towed diver surveys, which are conducted over larger spatial scales but with a lower level of taxonomic resolution.

Boundaries of fish replenishment areas (FRA) along the leeward (west) coast of Big Island in Hawaii. In order to replenish populations of heavily collected aquatic species, a network of FRAs comprising 35% of the coastline were established by the State of Hawaii in 1999 through the West Hawaii Regional Fisheries Management Area (FMA), administered by Hawaii's Division of Aquatic Resources (DAR). Though fishing is permitted (with some restrictions on lay net fishing), aquarium collecting is prohibited in these areas.

This data set contains sensitive biological resource data for native stream and anchialine pool fish species in coastal Hawaii. (Anchialine pools are small, relatively shallow coastal ponds that occur singly or in groups close to the shoreline. They have direct connections to the ocean either through surface channels or through subsurface cracks and fissures in the lava flows, and they experience regular tidal fluctuations in water levels.) Vector points in this data set represent species occurrences at stream mouths and in anchialine pools. 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 Hawaii. 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.
