Essential Fish Habitat
Imperative Fish Habitat (EFH) was defined by the U. S i9000. Congress in the 1996 changes to the Magnuson-Stevens Fishery Preservation and Management Act, or Magnuson-Stevens Act, as "those waters and substrate important to fish for spawning, breeding, nourishing or growth to maturity. "|1| Applying regulations clarified that marine environments include all aquatic areas and their physical, chemical, and biological properties; substrate contains the associated biological communities that make these areas suitable for fish habitats, and the explanation and identification of EFH should include habitats used without notice during the species' life routine.|2| EFH contains all types of aquatic habitat, just like wetlands, coral reefs, mud, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management local authorities to designate EFH making use of the best available scientific facts. EFH has been described for over a 1, 000 managed variety to date.|4| The main purpose of EFH regulations is usually to minimize the adverse effects of fishing and non angling impacts on EFH to the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Function was amended to establish a fresh requirements to identify and identify 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 fish species. Federal agencies need to consult with NOAA Fisheries the moment their actions or activities may adversely affect habitat identified by federal local fishery management councils or perhaps NOAA Fisheries as EFH.|6| On January 19, 1997, interim final rules were published in the Federal Register (Vol. sixty two, No . 244) which specify procedures for implementation of the EFH provisions of the Magnuson-Stevens Act.|7| These rules were amended by simply publication of final rules about January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management plan (FMP) amendment, and detail the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Has an effect on from certain fishing practices and coastal and marine development and may alter, harm, or destroy habitats necessary for fish. NOAA Fisheries, the regional fishery management local authorities (FMCs), and other federal organizations work together to minimize these risks.|13| Congress has created councils to classify unfavorable effects on fishes in relation to types of fishing gear, coast developments and non-point and point source pollution, as well as, evaluating how well every single fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed varieties. As new FMPs are developed, EFH for newly managed species will also be defined.|14| FMPs must describe and identify EFH for the fishery, decrease to the extent practicable the adverse effects of fishing on EFH, and identify different actions to encourage the conservation and enhancement of EFH.
Through consultations, NOAA Fisheries can recommend ways federal agencies may avoid or minimize the adverse effects of their actions within the habitat of federally supervised commercial and recreational fisheries.|16| Federal actions agencies which fund, permit, or carry out activities that may adversely affect EFH have to consult with NOAA Fisheries.|17| The federal actions agency must provide NOAA Fisheries with an diagnosis of all actions or proposed actions authorized, funded, or undertaken by the agency that may adversely affect EFH.|18| Then NOAA The fishing industry will provide the federal actions agency with EFH Preservation recommendations.|19| These kinds of Conservation Recommendations provide information on steer clear of, minimize, mitigate, or offset those adverse effects.|20| Federal action agencies must provide a written explanation to NOAA Fisheries if these recommendations have not been used.|21| NOAA The fishing industry must also include measures to reduce the adverse effects of sportfishing gear and fishing activities on EFH as well.|22| In addition , NOAA Fisheries and the FMCs may discuss and make recommendations to any state agency on their activities which may affect EFH.|23|
Most consultations are done in the NMFS regional offices: Greater Atlantic Regional Fisheries Workplace (GARFO), Southeast Regional Office (SERO), West Coast Regional Office (WCRO), Alaska Territorial Office (AKRO), and Ocean Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State organizations and private landowners are not needed to consult with NMFS. EFH consultation services are required if the federal government possesses authorized, funded, or done part or all of a proposed activity, and if the action will adversely have an impact on EFH.|24| Detrimentally affecting EFH includes direct or indirect physical, chemical or biological alterations on the waters or substrate and loss of, or injury to variety and their habitat, and other ecosystem components, or reduction from the quality and/or quantity of EFH.
Environment areas of particular concern or HAPCs are considered high priority areas for conservation, supervision, and research.|26| HAPCs are subsets of EFH that merit work because they meet by least one of the following four criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a an environment type that is/will get stressed by development;
include a habitat type that is uncommon.|27|
Current HAPCs contain important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, amongst other areas of interest. HAPCs will be afforded the same regulatory safeguard as EFH and do not banish activities from occurring inside the area, such as fishing, snorkeling, swimming or surfing.
Fundamental Fish Habitat is chosen for all federally managed seafood under the MSA whereas Crucial Habitat is designated meant for the survival and restoration of species listed since threatened or endangered beneath the Endangered Species Act (ESA).|29| Critical refuge include areas occupied by the threatened or endangered variety that include physical and scientific features that are essential to the conservation of the species.|30| Critical Habitat is designated as critical at the moment a species is listed beneath the ESA.|31| EFH and Critical Habitat vary in terms of designation and legislation, but they may overlap for certain species such as salmon.|32|
Natural environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures base the water surface, and marine community structures. These habitats are essential for fish and ecosystem health. The fundamental environment structure begins with residue. Erosion is stabilized by submerged aquatic vegetation. You will find two main types of bottoms, hard and smooth.|33| A study by Christensen at el. (2004) looked at three bottom natural environment types (vegetated marsh advantage, submerged aquatic vegetation, and shallow non-vegetated bottom) in relation to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the analysis showed that brown shrimp selected vegetated areas in salinities 15-25 ppt and they would select vegetated areas over marsh edges after 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 delivers 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 dry sponge. Areas of compacted or sheered mud and sediment can also be a form of hard bottom.|36|
Soft bottom consists of unconsolidated sediment and unvegetated areas. In some regions soft underside are not protected even though they might be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Attributes that affect soft lower part in relation to organisms that use them include sediment grain size, salinity, dissolved oxygen and flow.
