Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. H. Congress in the 1996 changes to the Magnuson-Stevens Fishery Conservation and Management Act, or Magnuson-Stevens Act, as "those waters and substrate necessary to fish for spawning, breeding, nourishing or growth to maturity. "|1| Utilizing regulations clarified that waters 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 information and identification of EFH should include habitats used without notice during the species' life spiral.|2| EFH comes with all types of aquatic habitat, just like wetlands, coral reefs, sand, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management councils to designate EFH making use of the best available scientific info. EFH has been described for over a 1, 000 managed variety to date.|4| The key purpose of EFH regulations should be 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 Action 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 provides jurisdiction over the management and conservation of marine fish species. Federal agencies need to consult with NOAA Fisheries the moment their actions or actions may adversely affect environment identified by federal local fishery management councils or NOAA Fisheries as EFH.|6| On January 19, 1997, interim final rules were published inside the Federal Register (Vol. sixty two, No . 244) which indicate procedures for implementation from the EFH provisions of the Magnuson-Stevens Act.|7| These kinds of rules were amended by simply publication of final rules about January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management plan (FMP) amendment, and detail the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Effects from certain fishing methods and coastal and underwater development and may alter, destruction, or destroy habitats essential for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal agencies work together to minimize these hazards.|13| Congress has created councils to classify unfavorable affects on fishes in relation to types of fishing gear, coast developments and nonpoint and point source pollution, and, evaluating how well each fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed types. 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, decrease to the extent practicable the adverse effects of fishing upon EFH, and identify various other actions to encourage the conservation and enhancement of EFH.
Through consultations, NOAA Fisheries can recommend ways federal agencies can avoid or minimize the adverse effects of their actions in the habitat of federally been able commercial and recreational fisheries.|16| Federal action agencies which fund, support, or carry out activities which may adversely affect EFH must consult with NOAA Fisheries.|17| The federal actions agency must provide NOAA Fisheries with an diagnosis of all actions or offered actions authorized, funded, or perhaps undertaken by the agency that may adversely affect EFH.|18| Then NOAA The fishing industry will provide the federal action agency with EFH Resource efficiency recommendations.|19| These kinds of Conservation Recommendations provide information on keep away from, 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 used.|21| NOAA The fishing industry must also include measures to reduce the adverse effects of reef fishing gear and fishing activities on EFH as well.|22| In addition , NOAA The fishing industry and the FMCs may comment on and make recommendations to any state agency on their actions 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 Regional Office (AKRO), and Pacific cycles Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State agencies and private landowners are not necessary to consult with NMFS. EFH consultations are required if the federal government possesses authorized, funded, or taken on part or all of a proposed activity, and if the action will adversely affect EFH.|24| Badly affecting EFH includes direct or indirect physical, chemical or biological alterations in the waters or substrate and loss of, or injury to species and their habitat, and other environment components, or reduction with the quality and/or quantity of EFH.
An environment areas of particular concern or perhaps HAPCs are considered high main concern areas for conservation, administration, and research.|26| HAPCs are subsets of EFH that merit special attention because they meet by least one of the following 5 criteria:
provide important environmental function;
are sensitive to environmental degradation;
include a an environment type that is/will be stressed by development;
will include a habitat type that is uncommon.|27|
Current HAPCs incorporate important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, among other areas of interest. HAPCs happen to 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 selected for all federally managed seafood under the MSA whereas Essential Habitat is designated meant for the survival and recovery of species listed seeing that threatened or endangered under the Endangered Species Act (ESA).|29| Critical habitats include areas occupied by threatened or endangered kinds that include physical and biological features that are essential to the conservation of the species.|30| Critical Habitat is certainly designated as critical at the moment a species is listed within the ESA.|31| EFH and Critical Habitat 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 root the water surface, and aquatic community structures. These case are essential for fish and ecosystem health. The fundamental home structure begins with sediment. Erosion is stabilized by simply submerged aquatic vegetation. There are two main types of bottoms, hard and delicate.|33| A study by simply Christensen at el. (2004) looked at three bottom home types (vegetated marsh edge, submerged aquatic vegetation, and shallow non-vegetated bottom) regarding juvenile brown shrimp (Farfantepenaeus aztecus). The results from the study showed that brown prawn selected vegetated areas in salinities 15-25 ppt plus they would select vegetated areas over marsh edges whenever 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 composition for attachment of sponges, seaweed, and coral, which support a diverse reef fish community.|35| This community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, a number of fin-fishes, alga, and a 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 bottoms are not protected even though they might be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Features that affect soft starting in relation to organisms that use them include sediment materials size, salinity, dissolved fresh air and flow.
