Essential Fish Habitat
Imperative Fish Habitat (EFH) was defined by the U. H. Congress in the 1996 changes to the Magnuson-Stevens Fishery Resource efficiency and Management Act, or Magnuson-Stevens Act, as "those waters and substrate necessary to fish for spawning, breeding, nourishing or growth to maturity. "|1| Utilizing regulations clarified that waters include all aquatic areas and their physical, chemical, and biological properties; substrate incorporates the associated biological areas that make these areas suitable for fish habitats, and the description and identification of EFH should include habitats used any time during the species' life cycle.|2| EFH comes with all types of aquatic habitat, such as wetlands, coral reefs, sand, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management councils to designate EFH making use of the best available scientific facts. EFH has been described for over a 1, 000 managed species to date.|4| The main purpose of EFH regulations is to minimize the adverse effects of fishing and non sportfishing impacts on EFH towards the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Action was amended to establish a new requirements to identify and explain EFH to protect, conserve and enhance EFH for the advantage of the fisheries.|5| The Magnuson-Stevens Act has jurisdiction over the management and conservation of marine seafood species. Federal agencies need to consult with NOAA Fisheries when their actions or actions may adversely affect an environment identified by federal local fishery management councils or NOAA Fisheries as EFH.|6| On Dec 19, 1997, interim last rules were published in the Federal Register (Vol. 62, No . 244) which indicate procedures for implementation of the EFH provisions of the Magnuson-Stevens Act.|7| These rules were amended by publication of final rules about January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management system (FMP) amendment, and depth the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Affects from certain fishing practices and coastal and submarine development and may alter, harm, or destroy habitats essential for fish. NOAA Fisheries, the regional fishery management local authorities (FMCs), and other federal firms work together to minimize these hazards.|13| Congress has created councils to classify unfavorable effects on fishes in relation to types of fishing gear, seaside developments and non-point and point source pollution, along with, evaluating how well each fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed species. As new FMPs are developed, EFH for recently managed species will also be described.|14| FMPs must describe and identify EFH for the fishery, minimize to the extent practicable the adverse effects of fishing upon EFH, and identify other actions to encourage the conservation and enhancement of EFH.
Through consultations, NOAA Fisheries can suggest ways federal agencies may avoid or minimize the adverse effects of their actions for the habitat of federally supervised commercial and recreational the fishing industry.|16| Federal actions agencies which fund, license, or carry out activities which may adversely affect EFH have to consult with NOAA Fisheries.|17| The federal action agency must provide NOAA Fisheries with an examination of all actions or offered actions authorized, funded, or perhaps undertaken by the agency that may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal actions agency with EFH Conservation recommendations.|19| These kinds of Conservation Recommendations provide information on keep away from, minimize, mitigate, or balance those adverse effects.|20| Federal action agencies must provide a written explanation to NOAA Fisheries if some of these recommendations have not been used.|21| NOAA The fishing industry must also include measures to reduce the adverse effects of fishing gear and fishing activities on EFH as well.|22| In addition , NOAA The fishing industry and the FMCs may comment on and make recommendations to the state agency on their activities which may affect EFH.|23|
Most consultations are done inside the NMFS regional offices: Increased Atlantic Regional Fisheries Office (GARFO), Southeast Regional Office (SERO), West Coast Territorial Office (WCRO), Alaska Territorial Office (AKRO), and Pacific Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State companies and private landowners are not forced to consult with NMFS. EFH services are required if the federal government features authorized, funded, or done part or all of a proposed activity, and if the action will adversely impact EFH.|24| Adversely affecting EFH includes immediate or indirect physical, chemical substance or biological alterations with the waters or substrate and loss of, or injury to types and their habitat, and other environment components, or reduction on the quality and/or quantity of EFH.
Habitat areas of particular concern or perhaps HAPCs are considered high priority areas for conservation, managing, and research.|26| HAPCs are subsets of EFH that merit work because they meet by least one of the following 5 criteria:
provide important environmental function;
are sensitive to environmental degradation;
include a home type that is/will get stressed by development;
add a habitat type that is exceptional.|27|
Current HAPCs incorporate important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, amongst other areas of interest. HAPCs happen to be afforded the same regulatory coverage as EFH and do not exclude activities from occurring inside the area, such as fishing, snorkeling, swimming or surfing.
Necessary Fish Habitat is chosen for all federally managed seafood under the MSA whereas Crucial Habitat is designated intended for the survival and restoration of species listed while threatened or endangered within the Endangered Species Act (ESA).|29| Critical case include areas occupied by threatened or endangered variety that include physical and biological features that are essential to the conservation of the species.|30| Critical Habitat is usually designated as critical at the time a species is listed under the ESA.|31| EFH and Critical Habitat differ in terms of designation and control, but they may overlap for many species such as salmon.|32|
An environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures underlying the water surface, and aquatic community structures. These refuge are essential for fish and ecosystem health. The fundamental environment structure begins with yeast sediment. Erosion is stabilized by submerged aquatic vegetation. You will find two main types of bottoms, hard and gentle.|33| A study simply by Christensen at el. (2004) looked at three bottom home types (vegetated marsh advantage, submerged aquatic vegetation, and shallow non-vegetated bottom) pertaining to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the study showed that brown prawn selected vegetated areas in salinities 15-25 ppt and would select vegetated areas over marsh edges when they co-occurred. Finding the areas that had the highest abundance helped to identify EFH of teenage brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom supplies hard complex vertical framework for attachment of a dry sponge, seaweed, and coral, which often support a diverse reef fish community.|35| This community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, a variety of fin-fishes, alga, and a sponge. Areas of compacted or sheered mud and sediment also are a form of hard bottom.|36|
Soft bottom consists of unconsolidated sediment and unvegetated areas. In some regions soft feet are not protected even though they can be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Attributes that affect soft bottom level in relation to organisms that make use of them include sediment grain size, salinity, dissolved breathable oxygen and flow.
