Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. T. Congress in the 1996 changes to the Magnuson-Stevens Fishery Resource efficiency and Management Act, or Magnuson-Stevens Act, as "those waters and substrate important to fish for spawning, breeding, feeding or growth to maturity. "|1| Utilizing regulations clarified that seas include all aquatic areas and their physical, chemical, and biological properties; substrate comes with the associated biological residential areas that make these areas ideal for fish habitats, and the explanation and identification of EFH should include habitats used any time during the species' life pattern.|2| EFH incorporates all types of aquatic habitat, such as wetlands, coral reefs, sand, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management local authorities to designate EFH using the best available scientific information. EFH has been described for more than a 1, 000 managed varieties to date.|4| The primary 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 Function was amended to establish a fresh requirements to identify and express EFH to protect, conserve and enhance EFH for the benefit 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 once their actions or actions may adversely affect environment identified by federal regional fishery management councils or perhaps NOAA Fisheries as EFH.|6| On January 19, 1997, interim last rules were published inside the Federal Register (Vol. over 60, No . 244) which indicate procedures for implementation of the EFH provisions of the Magnuson-Stevens Act.|7| These types of rules were amended 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 depth the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Impacts from certain fishing techniques and coastal and nautical development and may alter, harm, or destroy habitats important for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal companies work together to minimize these threats.|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, and, evaluating how well every fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed kinds. As new FMPs will be developed, EFH for newly managed species will also be identified.|14| FMPs must describe and identify EFH for the fishery, minimize to the extent practicable the adverse effects of fishing about EFH, and identify additional 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 around the habitat of federally handled commercial and recreational the fishing industry.|16| Federal actions agencies which fund, support, or carry out activities that may adversely affect EFH must 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 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 these recommendations have not been followed.|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 The fishing industry 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: Higher Atlantic Regional Fisheries Office (GARFO), Southeast Regional Office (SERO), West Coast Regional Office (WCRO), Alaska Regional Office (AKRO), and Ocean Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State firms and private landowners are not instructed to consult with NMFS. EFH consultations are required if the federal government possesses authorized, funded, or carried out part or all of a proposed activity, and if the action will adversely affect EFH.|24| Detrimentally affecting EFH includes immediate or indirect physical, chemical or biological alterations in the waters or substrate and loss of, or injury to varieties and their habitat, and other ecosystem components, or reduction with the quality and/or quantity of EFH.
Home 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 in least one of the following some 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 uncommon.|27|
Current HAPCs consist of important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, among other areas of interest. HAPCs are afforded the same regulatory safeguard as EFH and do not banish activities from occurring inside the area, such as fishing, snorkeling, swimming or surfing.
Essential Fish Habitat is selected for all federally managed seafood under the MSA whereas Important Habitat is designated meant for the survival and restoration of species listed while threatened or endangered beneath the Endangered Species Act (ESA).|29| Critical demeure 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 designated as critical during the time a species is listed within the ESA.|31| EFH and Critical Habitat are different in terms of designation and control, but they may overlap for sure species such as salmon.|32|
Habitat characteristics include sediment type, type of bottoms (sand, silt and clay), structures root the water surface, and aquatic 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 discover two main types of bottoms, hard and soft.|33| A study simply by Christensen at el. (2004) looked at three bottom habitat types (vegetated marsh edge, submerged aquatic vegetation, and shallow non-vegetated bottom) pertaining to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the research showed that brown prawn selected vegetated areas in salinities 15-25 ppt plus 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 juvenile brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom gives hard complex vertical structure for attachment of a sponge, seaweed, and coral, which in turn support a diverse reef fish 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 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. Qualities that affect soft lower part in relation to organisms that make use of them include sediment grain size, salinity, dissolved breathable oxygen and flow.
