Priority Ocean Areas for Protection in the Mid-Atlantic
Findings of NRDC's Marine Habitat Workshop
Benthic: of or pertaining to the bottom of a water body.
Biomass: the weight of a population of fish, the spawning adult portion of that population, or the weight of several populations.
Coral reefs: large living structures of calcium carbonate produced primarily by coral polyps. Polyps are tiny organisms that build and surround them-selves with calcium-carbonate skeletons. Coral reefs can range in size from a few feet to thousands of miles.
Crustaceans: a type of invertebrate that includes lobsters, crabs, shrimps, and barnacles. They characteristically have a segmented body and exoskeleton, and paired, jointed limbs.
Demersal: fish that live on or near the ocean bottom. Also called benthic fish, groundfish, or bottom fish.
Epifauna: benthic fauna living on the substrate (as on a hard seafloor) or on other organisms.
Exclusive Economic Zone (EEZ): adjacent to state waters, which extend 3 miles out from the coast. The U.S. EEZ includes waters from 3 to 200 nautical miles from shore.
Fishery: the combination of fish and fishers in a region, the latter fishing for similar or the same species with similar or the same gear types.
Fishery Management Council: one of eight regional councils around the United States that are responsible for developing Fishery Management Plans in each region. Evolved out of the Magnuson-Stevens Fishery Conservation and Management Act of 1976.
Habitat Area of Particular Concern (HAPC): a habitat area designated by a Fishery Management Council under the Magnuson-Stevens Fishery Conservation and Management Act of 1976.
Infauna: benthic fauna living in the substrate and especially in the soft seafloor.
Invertebrates: animals without a backbone. In fishery-management terms, this refers to shellfish, including lobsters, clams, shrimps, oysters, crabs, and sea urchins. Many other invertebrate species are not fished.
Isobath: a line on a map connecting points of equal bathymetry, i.e., equal depth, in the ocean or another water body.
Macrofauna: large animals (for example, fish).
Megafauna: larger animals (for example, whales).
Pelagic fish: fish that live in the open ocean at or near the water’s surface and usually migrate long distances. Examples include swordfish, tuna, and many species of shark.
