Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. Ersus. Congress in the 1996 amendments to the Magnuson-Stevens Fishery Resource efficiency and Management Act, or Magnuson-Stevens Act, as "those waters and substrate required to fish for spawning, breeding, feeding or growth to maturity. "|1| Putting into action regulations clarified that marine environments include all aquatic areas and their physical, chemical, and biological properties; substrate incorporates the associated biological neighborhoods that make these areas well suited for fish habitats, and the explanation and identification of EFH should include habitats used without notice during the species' life spiral.|2| EFH involves all types of aquatic habitat, such as wetlands, coral reefs, mud, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management councils to designate EFH using the best available scientific information. EFH has been described for over a 1, 000 managed varieties to date.|4| The primary purpose of EFH regulations is always to minimize the adverse effects of fishing and non sport fishing impacts on EFH towards the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Work was amended to establish a new requirements to identify and identify EFH to protect, conserve and enhance EFH for the advantage of the fisheries.|5| The Magnuson-Stevens Act possesses jurisdiction over the management and conservation of marine fish species. Federal agencies must consult with NOAA Fisheries when their actions or actions may adversely affect environment identified by federal territorial fishery management councils or NOAA Fisheries as EFH.|6| On December 19, 1997, interim last rules were published in the Federal Register (Vol. sixty two, No . 244) which stipulate procedures for implementation from the EFH provisions of the Magnuson-Stevens Act.|7| These kinds of rules were amended by publication of final rules on January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management plan (FMP) amendment, and fine detail the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Impacts from certain fishing routines and coastal and submarine development and may alter, damage, or destroy habitats important for fish. NOAA Fisheries, the regional fishery management local authorities (FMCs), and other federal companies work together to minimize these hazards.|13| Congress has established councils to classify unfavorable influences on fishes in relation to types of fishing gear, coastal developments and nonpoint and point source pollution, as well as, evaluating how well every fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed kinds. 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, decrease 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 recommend ways federal agencies can easily avoid or minimize the adverse effects of their actions around the habitat of federally supervised commercial and recreational fisheries.|16| Federal action agencies which fund, support, 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 examination of all actions or offered actions authorized, funded, or undertaken by the agency which may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal actions agency with EFH Conservation recommendations.|19| These types of Conservation Recommendations provide information on how to prevent, minimize, mitigate, or offset those adverse effects.|20| Federal action agencies need to provide a written explanation to NOAA Fisheries if any of these recommendations have not been adopted.|21| NOAA The fishing industry must also include measures to minimize the adverse effects of angling gear and fishing activities on EFH as well.|22| In addition , NOAA Fisheries and the FMCs may touch upon and make recommendations to the 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 Office (SERO), West Coast Local Office (WCRO), Alaska Local Office (AKRO), and Pacific Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State firms and private landowners are not forced to consult with NMFS. EFH consultations are required if the federal government has authorized, funded, or taken on 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 on the waters or substrate and loss of, or injury to types and their habitat, and other environment 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, management, and research.|26| HAPCs are subsets of EFH that merit attention because they meet at least one of the following 5 criteria:
provide important environmental function;
are sensitive to environmental degradation;
include a natural environment type that is/will get stressed by development;
add a habitat type that is exceptional.|27|
Current HAPCs consist of important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, among other areas of interest. HAPCs will be afforded the same regulatory protection as EFH and do not leave out activities from occurring in the area, such as fishing, snorkeling, swimming or surfing.
Essential Fish Habitat is specified for all federally managed fish under the MSA whereas Important Habitat is designated to get the survival and restoration of species listed because threatened or endangered underneath the Endangered Species Act (ESA).|29| Critical case include areas occupied by the threatened or endangered types that include physical and scientific features that are essential to the conservation of the species.|30| Critical Habitat is definitely designated as critical at the moment a species is listed underneath the ESA.|31| EFH and Critical Habitat are different in terms of designation and regulation, but they may overlap for several species such as salmon.|32|
Natural environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures base the water surface, and aquatic community structures. These g?te are essential for fish and ecosystem health. The fundamental natural environment structure begins with residue. Erosion is stabilized by simply submerged aquatic vegetation. You will discover two main types of bottoms, hard and delicate.|33| A study by simply Christensen at el. (2004) looked at three bottom environment types (vegetated marsh edge, submerged aquatic vegetation, and shallow non-vegetated bottom) with regards to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the analysis showed that brown prawn selected vegetated areas in salinities 15-25 ppt and in addition they would select vegetated areas over marsh edges when 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 gives hard complex vertical framework for attachment of a dry sponge, seaweed, and coral, which in turn support a diverse reef seafood community.|35| This community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, various 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 may be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Features that affect soft bottom level in relation to organisms that employ them include sediment materials size, salinity, dissolved air and flow.
