Survey distribution maps created through analysis of species distributions from surveys using various gear types for scallop species in the Scallop Fishery Management Plan, including areas of the Bering Sea, Aleutian Islands, and Gulf of Alaska.

Species distribution model maps created through analysis of NMFS bottom-trawl surveys and habitat covariates for groundfish species in the Gulf of Alaska Groundfish Fishery Management Plan.

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 biological resource data for estuarine, benthic, and pelagic fish in Southeast Alaska. Vector polygons in this data set represent locations of fish concentration areas. 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 Southeast Alaska. 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 FISHL (Fish Lines) and FISHPT (Fish Points) data layers, part of the larger Southeast Alaska ESI database, for additional fish information.

This data set contains biological resource data for anadromous fish streams in Southeast Alaska. Vector points in this data set represent locations of fish streams.

This archive information package contains fish presence and stream habitat data collected in southeast Alaska, between May 2017 and October 2020 to identify anadromous fish stream habitat. During this time the Alaska Department of Fish and Game Habitat Section staff completed 1,051 stream surveys in remote and urban areas, using backpack electrofisher, fish traps, clinometers, tape measures, and rangefinder/hypsometer. Data collected include fish species presence, notable fish habitat features, substrate characteristics, fish barriers, and other additional notes. These data are provided in both Excel spreadsheet and ESRI shapefile formats.

Essential Fish Habitat (EFH) maps depict the area of EFH for each life stage of fish managed under a Fishery Management Plan within the Gulf of Alaska, Bering Sea, Aleutian Islands, and Arctic. EFH shapefiles were created by Region (AI, BS, GOA, Arctic) and life stage.
