Habitat Overview

Regional Fishery Management Councils are required to designate essential fish habitat (EFH) and minimize the impacts of fishing in those areas to the extent practicable. The NEFMC’s 2018 Omnibus EFH Amendment 2 includes current EFH designations for 28 managed stocks.

In January 2025, the Council completed a technical review of EFH information. This review along with the Northeast Regional Habitat Assessment informed the framework actions that will revise 2025 EFH designations for:

• Atlantic cod
• Atlantic herring
• Monkfish
• Skates

Additional actions will follow in 2026 and 2027 for other species.

To evaluate fishing impacts on EFH, the Council uses the Fishing Effects Model. The previous version of this model, the Swept Area Seabed Impact Model, was used in OHA2 to develop and update habitat management areas that restrict specific gear types in certain locations.

Other recent actions addressing fishing effects on habitat include the Clam Dredge Exemption Framework (2020) and the Deep-Sea Coral Amendment (2021) and the discontinued Northern Edge Habitat Scallop Framework (2024).
Habitat Areas of Particular Concern (HAPC) highlight habitats in need of additional conservation. These designations are routinely referenced during EFH consultations that are administered by NOAA Fisheries. The latest Council HAPC in Southern New England, is intended to foster development of conservation recommendations that avoid, minimize, and mitigate impacts from offshore development.

The Council collaborates with other habitat-focused organizations, including the Atlantic States Marine Fisheries Commission’s Habitat Committee and the Atlantic Coastal Fish Habitat Partnership, which the Council joined in 2024.

The Habitat Committee also supports coordinated regional science and monitoring including collaboration with the Mid-Atlantic Fishery Management Council to prepare comment letters to the Bureau of Ocean Energy Management (BOEM) and other agencies.

Plan Amendments, Frameworks, and Specifications

Plan Amendments

April 9, 2018
This action implements approved regulations for the New England Fishery Management Council’s Omnibus Essential Fish Habitat Amendment 2. This rule revises essential fish habitat and habitat area of particular concern designations, revises or creates habitat management areas, including gear restrictions, to protect vulnerable habitat from fishing gear impacts, establishes dedicated habitat research areas, and implements several administrative measures related to reviewing these measures, as well as other regulatory adjustments to implement these measures. This action is necessary to comply with the requirements of the Magnuson-Stevens Fishery Conservation and Management Act to periodically review essential fish habitat designations and protections. The measures are designed to minimize to the extent practicable the adverse effects of fishing on essential fish habitat.
June 25, 2021
The Deep-Sea Coral Amendment includes management areas to protect coral habitat from the impacts of fishing gears, provisions to encourage further research on deep-sea corals and fisheries, and measures to facilitate future updates to coral management approaches.
April 21, 1999
Omnibus Habitat Amendment 1 (OHA1) was prepared by the New England Fishery Management Council (NEFMC) to implement the essential fish habitat (EFH) provisions of the Magnuson-Stevens Fishery Conservation and Management Act as reauthorized in 1996.

Framework Adjustments/Specifications

February 5, 2024
This omnibus action establishes a new Habitat Area of Particular Concern (HAPC) in Southern New England through framework adjustments to the groundfish, scallop, monkfish, skate, and Atlantic herring plans.
May 19, 2020
This framework adjustment would allow surfclam and mussel dredging under restrictive conditions in the Great South Channel Habitat Management Area (GSC HMA).
