Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. T. Congress in the 1996 changes to the Magnuson-Stevens Fishery Conservation and Management Act, or perhaps Magnuson-Stevens Act, as "those waters and substrate essential to fish for spawning, breeding, nourishing or growth to maturity. "|1| Putting into action regulations clarified that waters include all aquatic areas and their physical, chemical, and biological properties; substrate involves the associated biological neighborhoods that make these areas suited to fish habitats, and the information and identification of EFH should include habitats used at any time during the species' life routine.|2| EFH comes with all types of aquatic habitat, such as wetlands, coral reefs, fine sand, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management local authorities to designate EFH using the best available scientific info. EFH has been described for over a 1, 000 managed varieties to date.|4| The primary purpose of EFH regulations should be to minimize the adverse effects of fishing and non reef fishing impacts on EFH towards the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Work was amended to establish a fresh requirements to identify and express EFH to protect, conserve and enhance EFH for the advantage 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 the moment their actions or actions may adversely affect natural environment identified by federal local fishery management councils or perhaps NOAA Fisheries as EFH.|6| On January 19, 1997, interim final rules were published inside the Federal Register (Vol. over 60, No . 244) which stipulate procedures for implementation of the EFH provisions of the Magnuson-Stevens Act.|7| These types of rules were amended simply by publication of final rules on January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management system (FMP) amendment, and aspect the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Influences from certain fishing practices 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 organizations work together to minimize these risks.|13| Congress has created councils to classify unfavorable impacts on fishes in relation to types of fishing gear, coastal developments and non-point and point source pollution, and also, 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 identified.|14| FMPs need to describe and identify EFH for the fishery, lessen to the extent practicable the adverse effects of fishing on EFH, and identify additional actions to encourage the conservation and enhancement of EFH.
Through consultations, NOAA Fisheries can recommend ways federal agencies may avoid or minimize the adverse effects of their actions around the habitat of federally supervised commercial and recreational fisheries.|16| Federal actions agencies which fund, grant, or carry out activities which may adversely affect EFH are required to consult with NOAA Fisheries.|17| The federal actions agency must provide NOAA Fisheries with an analysis of all actions or suggested 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 kinds of Conservation Recommendations provide information on steer clear of, minimize, mitigate, or counter those adverse effects.|20| Federal action agencies need to provide a written explanation to NOAA Fisheries if some of these recommendations have not been implemented.|21| NOAA The fishing industry must also include measures to reduce the adverse effects of angling gear and fishing actions on EFH as well.|22| In addition , NOAA Fisheries and the FMCs may touch upon and make recommendations to the state agency on their actions which may affect EFH.|23|
Most consultations are done inside the NMFS regional offices: Greater Atlantic Regional Fisheries Workplace (GARFO), Southeast Regional Workplace (SERO), West Coast Territorial 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 organizations and private landowners are not forced to consult with NMFS. EFH consultations are required if the federal government provides authorized, funded, or undertaken part or all of a proposed activity, and if the action will adversely have an effect on EFH.|24| Detrimentally 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 ecosystem components, or reduction of the quality and/or quantity of EFH.
Habitat areas of particular concern or HAPCs are considered high goal areas for conservation, control, and research.|26| HAPCs are subsets of EFH that merit attention because they meet in least one of the following 4 criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a an environment type that is/will come to be stressed by development;
include a habitat type that is rare.|27|
Current HAPCs contain important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, between other areas of interest. HAPCs will be afforded the same regulatory safeguard as EFH and do not banish activities from occurring inside the area, such as fishing, snorkeling, swimming or surfing.
Fundamental Fish Habitat is specified for all federally managed fish under the MSA whereas Important Habitat is designated for the survival and restoration of species listed seeing that threatened or endangered beneath the Endangered Species Act (ESA).|29| Critical case 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 is definitely designated as critical at that moment a species is listed underneath the ESA.|31| EFH and Critical Habitat are different in terms of designation and control, but they may overlap for certain species such as salmon.|32|
Natural environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures root the water surface, and marine community structures. These g?te are essential for fish and ecosystem health. The fundamental an environment structure begins with sediment. Erosion is stabilized by 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 advantage, submerged aquatic vegetation, and shallow non-vegetated bottom) in terms of juvenile brown shrimp (Farfantepenaeus aztecus). The results from the study showed that brown shrimp selected vegetated areas in salinities 15-25 ppt plus 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 gives hard complex vertical structure for attachment of a dry sponge, seaweed, and coral, which often support a diverse reef fish community.|35| This kind of community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, a range of fin-fishes, alga, and sponges. 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 are often primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Features that affect soft bottom in relation to organisms that make use of them include sediment grain size, salinity, dissolved air and flow.
