Essential Fish Habitat
Imperative Fish Habitat (EFH) was defined by the U. Ersus. Congress in the 1996 changes to the Magnuson-Stevens Fishery Conservation and Management Act, or Magnuson-Stevens Act, as "those waters and substrate required 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 neighborhoods that make these areas suited to fish habitats, and the information and identification of EFH should include habitats used any time during the species' life routine.|2| EFH includes all types of aquatic habitat, just like wetlands, coral reefs, yellow 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 data. EFH has been described for more than a 1, 000 managed types to date.|4| The key purpose of EFH regulations is usually to minimize the adverse effects of fishing and non fishing impacts on EFH for the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Work was amended to establish a fresh requirements to identify and explain EFH to protect, conserve and enhance EFH for the benefit of the fisheries.|5| The Magnuson-Stevens Act provides jurisdiction over the management and conservation of marine seafood species. Federal agencies need to consult with NOAA Fisheries when ever their actions or actions may adversely affect habitat identified by federal local fishery management councils or NOAA Fisheries as EFH.|6| On 12 19, 1997, interim final rules were published in the Federal Register (Vol. 62, No . 244) which indicate procedures for implementation from 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 program (FMP) amendment, and aspect the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Effects from certain fishing techniques and coastal and nautical development and may alter, destruction, or destroy habitats necessary for fish. NOAA Fisheries, the regional fishery management local authorities (FMCs), and other federal agencies work together to minimize these threats.|13| Congress has established councils to classify unfavorable affects on fishes in relation to types of fishing gear, coast developments and non-point and point source pollution, and, 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 identified.|14| FMPs must describe and identify EFH for the fishery, reduce 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 can avoid or minimize the adverse effects of their actions around the habitat of federally handled commercial and recreational the fishing industry.|16| Federal actions agencies which fund, permit, 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 examination of all actions or offered actions authorized, funded, or undertaken by the agency that may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal actions agency with EFH Resource efficiency recommendations.|19| These Conservation Recommendations provide information on how to avoid, minimize, mitigate, or balance those adverse effects.|20| Federal action agencies must provide a written explanation to NOAA Fisheries if these recommendations have not been followed.|21| NOAA The fishing industry must also include measures to minimize the adverse effects of fishing gear and fishing activities on EFH as well.|22| In addition , NOAA Fisheries and the FMCs may touch upon and make recommendations to any state agency on their actions which may affect EFH.|23|
Most consultations are done in the NMFS regional offices: Higher Atlantic Regional Fisheries Office (GARFO), Southeast Regional Office (SERO), West Coast Local 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 agencies and private landowners are not necessary to consult with NMFS. EFH discussions are required if the federal government offers authorized, funded, or done part or all of a proposed activity, and if the action will adversely impact EFH.|24| Negatively affecting EFH includes direct or indirect physical, chemical or biological alterations on the waters or substrate and loss of, or injury to species and their habitat, and other ecosystem components, or reduction in the quality and/or quantity of EFH.
Habitat areas of particular concern or HAPCs are considered high priority areas for conservation, administration, and research.|26| HAPCs are subsets of EFH that merit attention because they meet in least one of the following four criteria:
provide important environmental function;
are sensitive to environmental degradation;
include a an environment type that is/will be stressed by development;
incorporate a habitat type that is uncommon.|27|
Current HAPCs involve 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, snorkeling, swimming or surfing.
Essential Fish Habitat is designated for all federally managed fish under the MSA whereas Essential Habitat is designated intended for the survival and recovery of species listed because threatened or endangered underneath the Endangered Species Act (ESA).|29| Critical refuge include areas occupied by 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 during the time a species is listed beneath the ESA.|31| EFH and Critical Habitat are different in terms of designation and legislation, but they may overlap for sure species such as salmon.|32|
Environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures underlying the water surface, and marine community structures. These habitats are essential for fish and ecosystem health. The fundamental natural environment structure begins with crud. Erosion is stabilized by simply submerged aquatic vegetation. There are two main types of bottoms, hard and soft.|33| A study by simply Christensen at el. (2004) looked at three bottom home types (vegetated marsh edge, submerged aquatic vegetation, and shallow non-vegetated bottom) with regards to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the research showed that brown shrimp selected vegetated areas in salinities 15-25 ppt and would select vegetated areas over marsh edges if they co-occurred. Finding the areas that had the highest abundance helped to identify EFH of young , small brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom provides hard complex vertical composition for attachment of a sponge, seaweed, and coral, which 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 also are 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 are often primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Attributes that affect soft lower side in relation to organisms that use them include sediment wheat size, salinity, dissolved oxygen and flow.
