Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. H. Congress in the 1996 changes to the Magnuson-Stevens Fishery Preservation and Management Act, or Magnuson-Stevens Act, as "those waters and substrate important to fish for spawning, breeding, nourishing 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 residential areas that make these areas suited to fish habitats, and the information and identification of EFH should include habitats used anytime during the species' life cycle.|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 councils to designate EFH making use of the best available scientific details. EFH has been described for more than a 1, 000 managed variety to date.|4| The key purpose of EFH regulations is to minimize the adverse effects of fishing and non reef fishing impacts on EFH for the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Work was amended to establish a brand 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 offers jurisdiction over the management and conservation of marine seafood species. Federal agencies need to consult with NOAA Fisheries when ever their actions or activities may adversely affect natural environment identified by federal regional fishery management councils or perhaps 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 with the EFH provisions of the Magnuson-Stevens Act.|7| These 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 system (FMP) amendment, and detail the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Affects from certain fishing practices and coastal and marine development and may alter, destruction, or destroy habitats important for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal agencies work together to minimize these dangers.|13| Congress has established councils to classify unfavorable influences on fishes in relation to types of fishing gear, seaside developments and nonpoint 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 varieties. As new FMPs are developed, EFH for newly managed species will also be described.|14| FMPs need to describe and identify EFH for the fishery, lessen 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 can 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, licenses, or carry out activities which may adversely affect EFH are required to consult with NOAA Fisheries.|17| The federal action agency must provide NOAA Fisheries with an analysis of all actions or suggested actions authorized, funded, or perhaps 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 Conservation Recommendations provide information on keep away from, minimize, mitigate, or counteract those adverse effects.|20| Federal action agencies need to provide a written explanation to NOAA Fisheries if these recommendations have not been implemented.|21| NOAA The fishing industry must also include measures to reduce the adverse effects of sportfishing gear and fishing actions on EFH as well.|22| In addition , NOAA Fisheries and the FMCs may touch upon and make recommendations to any state agency on their activities which may affect EFH.|23|
Most consultations are done in the NMFS regional offices: Greater Atlantic Regional Fisheries Business office (GARFO), Southeast Regional Business 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 instructed to consult with NMFS. EFH services are required if the federal government has authorized, funded, or carried out part or all of a proposed activity, and if the action will adversely affect EFH.|24| Negatively affecting EFH includes direct or indirect physical, substance or biological alterations with the waters or substrate and loss of, or injury to species and their habitat, and other ecosystem components, or reduction of the quality and/or quantity of EFH.
Habitat areas of particular concern or perhaps HAPCs are considered high top 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 some criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a habitat type that is/will come to be stressed by development;
add a habitat type that is unusual.|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 security as EFH and do not rule out activities from occurring inside the area, such as fishing, diving, swimming or surfing.
Imperative Fish Habitat is designated for all federally managed seafood under the MSA whereas Vital Habitat is designated meant for the survival and restoration of species listed as threatened or endangered underneath the Endangered Species Act (ESA).|29| Critical demeure include areas occupied by threatened or endangered species that include physical and biological features that are essential to the conservation of the species.|30| Critical Habitat is usually designated as critical at that moment a species is listed beneath the ESA.|31| EFH and Critical Habitat are different in terms of designation and regulation, but they may overlap for sure species such as salmon.|32|
Home characteristics include sediment type, type of bottoms (sand, silt and clay), structures base the water surface, and marine community structures. These habitats are essential for fish and ecosystem health. The fundamental an environment structure begins with crud. Erosion is stabilized simply by submerged aquatic vegetation. There are two main types of bottoms, hard and very soft.|33| A study by simply Christensen at el. (2004) looked at three bottom an environment types (vegetated marsh edge, submerged aquatic vegetation, and shallow non-vegetated bottom) in relation to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the analysis showed that brown prawn 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 supplies hard complex vertical structure for attachment of a dry 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 range of fin-fishes, alga, and sponges. 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 bottoms are not protected even though they can be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Features that affect soft lower part in relation to organisms that employ them include sediment materials size, salinity, dissolved fresh air and flow.
