Essential Fish Habitat
Essential Fish Habitat (EFH) was defined by the U. H. Congress in the 1996 changes to the Magnuson-Stevens Fishery Preservation and Management Act, or Magnuson-Stevens Act, as "those waters and substrate essential to fish for spawning, breeding, feeding or growth to maturity. "|1| Putting into action regulations clarified that waters include all aquatic areas and their physical, chemical, and biological properties; substrate incorporates the associated biological neighborhoods that make these areas ideal for fish habitats, and the explanation and identification of EFH should include habitats used at any time during the species' life routine.|2| EFH includes all types of aquatic habitat, including wetlands, coral reefs, sand, 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 species to date.|4| The key purpose of EFH regulations is usually to minimize the adverse effects of fishing and non sportfishing impacts on EFH to the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Take action was amended to establish a brand new requirements to identify and express EFH to protect, conserve and enhance EFH for the benefit of the fisheries.|5| The Magnuson-Stevens Act features jurisdiction over the management and conservation of marine fish species. Federal agencies must consult with NOAA Fisheries the moment their actions or actions may adversely affect natural environment identified by federal regional fishery management councils or perhaps NOAA Fisheries as EFH.|6| On January 19, 1997, interim final rules were published in the Federal Register (Vol. over 60, No . 244) which specify procedures for implementation in the EFH provisions of the Magnuson-Stevens Act.|7| These kinds of rules were amended simply by publication of final rules upon January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management strategy (FMP) amendment, and aspect the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Influences from certain fishing techniques and coastal and underwater development and may alter, harm, or destroy habitats important for fish. NOAA Fisheries, the regional fishery management local authorities (FMCs), and other federal firms work together to minimize these hazards.|13| Congress has established councils to classify unfavorable affects on fishes in relation to types of fishing gear, coastal 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 varieties. As new FMPs happen to be developed, EFH for recently managed species will also be defined.|14| FMPs need to describe and identify EFH for the fishery, lessen to the extent practicable the adverse effects of fishing in EFH, and identify various other actions to encourage the conservation and enhancement of EFH.
Through consultations, NOAA Fisheries can recommend ways federal agencies can avoid or minimize the adverse effects of their actions within the habitat of federally managed commercial and recreational fisheries.|16| Federal actions agencies which fund, support, or carry out activities that may adversely affect EFH are required to consult with NOAA Fisheries.|17| The federal actions agency must provide NOAA Fisheries with an assessment of all actions or recommended actions authorized, funded, or undertaken by the agency that may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal action agency with EFH Resource efficiency recommendations.|19| These types of Conservation Recommendations provide information on how to prevent, minimize, mitigate, or balance out those adverse effects.|20| Federal action agencies need to provide a written explanation to NOAA Fisheries if these recommendations have not been used.|21| NOAA Fisheries must also include measures to reduce the adverse effects of angling gear and fishing activities on EFH as well.|22| In addition , NOAA The fishing industry and the FMCs may discuss and make recommendations to any state agency on their activities which may affect EFH.|23|
Most consultations are done inside the NMFS regional offices: Better Atlantic Regional Fisheries Office (GARFO), Southeast Regional Workplace (SERO), West Coast Regional Office (WCRO), Alaska Local Office (AKRO), and Pacific cycles Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State companies and private landowners are not required to consult with NMFS. EFH services are required if the federal government features authorized, funded, or performed part or all of a proposed activity, and if the action will adversely have an effect on EFH.|24| Negatively affecting EFH includes immediate or indirect physical, chemical substance or biological alterations of the waters or substrate and loss of, or injury to variety and their habitat, and other environment components, or reduction of the quality and/or quantity of EFH.
Environment areas of particular concern or perhaps HAPCs are considered high main concern areas for conservation, supervision, and research.|26| HAPCs are subsets of EFH that merit special attention because they meet at least one of the following some criteria:
provide important environmental function;
are sensitive to environmental degradation;
include a 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, between other areas of interest. HAPCs happen to be afforded the same regulatory coverage as EFH and do not banish activities from occurring inside the area, such as fishing, diving, swimming or surfing.
Essential Fish Habitat is designated for all federally managed fish under the MSA whereas Essential Habitat is designated for the survival and restoration of species listed as threatened or endangered underneath the Endangered Species Act (ESA).|29| Critical habitats include areas occupied by the threatened or endangered varieties that include physical and neurological features that are essential to the conservation of the species.|30| Critical Habitat is designated as critical during the time a species is listed beneath the ESA.|31| EFH and Critical Habitat vary in terms of designation and regulation, but they may overlap for many species such as salmon.|32|
Natural environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures hidden the water surface, and marine community structures. These demeure are essential for fish and ecosystem health. The fundamental environment structure begins with crud. Erosion is stabilized by simply 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 home types (vegetated marsh edge, submerged aquatic vegetation, and shallow non-vegetated bottom) in relation to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the study showed that brown shrimp selected vegetated areas in salinities 15-25 ppt and in addition they would select vegetated areas over marsh edges if 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 composition for attachment of a dry sponge, seaweed, and coral, which often support a diverse reef seafood community.|35| This community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, a range of fin-fishes, alga, and a dry sponge. Areas of compacted or sheered mud and sediment are usually 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. Features that affect soft bottom in relation to organisms that use them include sediment wheat size, salinity, dissolved fresh air and flow.
