Essential Fish Habitat
Fundamental Fish Habitat (EFH) was defined by the U. S i9000. Congress in the 1996 amendments to the Magnuson-Stevens Fishery Resource efficiency and Management Act, or perhaps Magnuson-Stevens Act, as "those waters and substrate important to fish for spawning, breeding, feeding or growth to maturity. "|1| Putting into action regulations clarified that lakes and rivers include all aquatic areas and their physical, chemical, and biological properties; substrate incorporates the associated biological organizations that make these areas ideal for fish habitats, and the information and identification of EFH should include habitats used anytime during the species' life routine.|2| EFH includes all types of aquatic habitat, including wetlands, coral reefs, yellow sand, 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 more than a 1, 000 managed kinds to date.|4| The key purpose of EFH regulations is always 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 new requirements to identify and describe EFH to protect, conserve and enhance EFH for the main benefit of the fisheries.|5| The Magnuson-Stevens Act possesses jurisdiction over the management and conservation of marine fish species. Federal agencies need to consult with NOAA Fisheries when ever their actions or activities may adversely affect an environment identified by federal regional fishery management councils or perhaps NOAA Fisheries as EFH.|6| On 12 , 19, 1997, interim last rules were published inside the Federal Register (Vol. over 60, No . 244) which indicate procedures for implementation in the EFH provisions of the Magnuson-Stevens Act.|7| These types of rules were amended by simply publication of final rules on January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management strategy (FMP) amendment, and depth the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Influences from certain fishing procedures and coastal and underwater development and may alter, damage, or destroy habitats necessary for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal companies work together to minimize these dangers.|13| Congress has created councils to classify unfavorable affects 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 fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed variety. As new FMPs happen to be developed, EFH for recently managed species will also be described.|14| FMPs must describe and identify EFH for the fishery, reduce to the extent practicable the adverse effects of fishing upon EFH, and identify additional actions to encourage the conservation and enhancement of EFH.
Through consultations, NOAA Fisheries can suggest ways federal agencies can easily avoid or minimize the adverse effects of their actions on the habitat of federally maintained commercial and recreational the fishing industry.|16| Federal action 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 offered 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 types of Conservation Recommendations provide information on how to prevent, 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 adopted.|21| NOAA Fisheries must also include measures to reduce the adverse effects of fishing gear and fishing actions on EFH as well.|22| In addition , NOAA The fishing industry and the FMCs may discuss and make recommendations to the state agency on their actions which may affect EFH.|23|
Most consultations are done in the NMFS regional offices: Better Atlantic Regional Fisheries Workplace (GARFO), Southeast Regional Office (SERO), West Coast Regional Office (WCRO), Alaska Regional Office (AKRO), and Pacific cycles Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State businesses and private landowners are not instructed to consult with NMFS. EFH consultation services are required if the federal government has authorized, funded, or performed part or all of a proposed activity, and if the action will adversely influence EFH.|24| Negatively affecting EFH includes direct 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 with the quality and/or quantity of EFH.
Environment areas of particular concern or perhaps HAPCs are considered high priority areas for conservation, control, and research.|26| HAPCs are subsets of EFH that merit special attention because they meet at least one of the following 4 criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a habitat type that is/will come to be stressed by development;
will include a habitat type that is unusual.|27|
Current HAPCs involve 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.
Necessary Fish Habitat is chosen for all federally managed fish under the MSA whereas Crucial Habitat is designated to get the survival and recovery of species listed while threatened or endangered under the Endangered Species Act (ESA).|29| Critical habitats include areas occupied by the threatened or endangered variety that include physical and natural features that are essential to the conservation of the species.|30| Critical Habitat can be designated as critical at the moment a species is listed beneath the ESA.|31| EFH and Critical Habitat will vary in terms of designation and rules, but they may overlap for certain species such as salmon.|32|
Habitat characteristics include sediment type, type of bottoms (sand, silt and clay), structures base the water surface, and marine community structures. These refuge are essential for fish and ecosystem health. The fundamental natural environment structure begins with crud. Erosion is stabilized simply 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 habitat types (vegetated marsh advantage, 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 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 provides hard complex vertical composition for attachment of a dry sponge, seaweed, and coral, which in turn support a diverse reef fish community.|35| This kind of 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 are also 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 could be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Characteristics that affect soft starting in relation to organisms that utilize them include sediment grain size, salinity, dissolved o2 and flow.
