Essential Fish Habitat Mapper

December 07, 2017

The EFH Mapper is a one-stop tool for viewing the spatial representations of fish species, their life stages and important habitats. We provide links to supporting materials, including fishery management plans, and the ability to download GIS data.

This one-of-a-kind tool displays maps for essential fish habitat, habitat areas of particular concern, and EFH areas protected from fishing. You can discover the species that spawn, grow, or live in a chosen location on the map and generate a report with supporting documentation. For species with distinct life-stages, the map offers locations for each individual stage. It includes NOAA nautical charts, which are updated monthly and immediately available through the EFH Mapper. You can use the transparency sliders to view underlying ocean and nautical chart base maps. The ocean base map includes surface and subsurface feature names and derived depths.
