EFH is defined as those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity. \n\nThis layer represents an overlay of EFH polygons for numerous species, including American Plaice, Atlantic Cod, Atlantic Halibut, Atlantic Herring, Atlantic Sea Scallop, Atlantic Wolffish, Barndoor Skate, Black Sea Bass, Bluefish, Butterfish, Clearnose Skate, Haddock, Little Skate, Longfin Inshore Squid, Mackerel, Monkfish, Northern Shortfin Squid, Ocean Pout, Offshore Hake, Pollock, Quahog, Redfish, Red Crab, Red Hake, Rosette Skate, Scup, Silver Hake, Smooth Skate, Spiny Dogfish, Surfclam, Summer Flounder, Tilefish, Thorny Skate, White Hake, Windowpane Flounder, Winter Flounder, Winter Skate, Witch Flounder, and Yellowtail Flounder. This layer was developed for general visualization and informational purposes only and does not necessarily represent the most important habitats. The Nature Conservancy obtained individual EFH layers from NOAA. The data presented here do not represent EFH for individual species but rather the number of overlapping EFH in any given location.
