Essential Fish Habitat
Fundamental Fish Habitat (EFH) was defined by the U. S i9000. 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| Employing regulations clarified that marine environments include all aquatic areas and their physical, chemical, and biological properties; substrate incorporates the associated biological areas that make these areas well suited for fish habitats, and the explanation and identification of EFH should include habitats used any time during the species' life cycle.|2| EFH incorporates all types of aquatic habitat, such as wetlands, coral reefs, mud, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management councils to designate EFH using the best available scientific info. EFH has been described for over a 1, 000 managed varieties to date.|4| The main purpose of EFH regulations is usually to minimize the adverse effects of fishing and non angling impacts on EFH towards the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Action was amended to establish a brand new requirements to identify and illustrate EFH to protect, conserve and enhance EFH for the benefit of the fisheries.|5| The Magnuson-Stevens Act offers jurisdiction over the management and conservation of marine fish species. Federal agencies must consult with NOAA Fisheries when ever their actions or actions may adversely affect natural environment identified by federal territorial fishery management councils or NOAA Fisheries as EFH.|6| On 12 , 19, 1997, interim last rules were published inside the Federal Register (Vol. sixty two, No . 244) which stipulate procedures for implementation on 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 approach (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, destruction, 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 established councils to classify unfavorable has an effect on on fishes in relation to types of fishing gear, coast developments and nonpoint and point source pollution, as well as, evaluating how well each 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 must describe and identify EFH for the fishery, minimize to the extent practicable the adverse effects of fishing upon EFH, and identify other 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 within the habitat of federally managed commercial and recreational fisheries.|16| Federal action agencies which fund, grant, or carry out activities which may adversely affect EFH have to consult with NOAA Fisheries.|17| The federal action agency must provide NOAA Fisheries with an assessment of all actions or recommended 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 Resource efficiency recommendations.|19| These Conservation Recommendations provide information on how to prevent, minimize, mitigate, or balance out those adverse effects.|20| Federal action agencies must provide a written explanation to NOAA Fisheries if these recommendations have not been followed.|21| NOAA The fishing industry must also include measures to minimize the adverse effects of angling 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 the state agency on their actions which may affect EFH.|23|
Most consultations are done in the NMFS regional offices: Increased Atlantic Regional Fisheries Workplace (GARFO), Southeast Regional Business office (SERO), West Coast Territorial Office (WCRO), Alaska Territorial Office (AKRO), and Ocean 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 services are required if the federal government offers authorized, funded, or undertaken part or all of a proposed activity, and if the action will adversely have an impact on EFH.|24| Adversely affecting EFH includes immediate or indirect physical, chemical or biological alterations from the waters or substrate and loss of, or injury to kinds and their habitat, and other ecosystem components, or reduction with 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 by least one of the following 5 criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a home type that is/will get stressed by development;
incorporate a habitat type that is rare.|27|
Current HAPCs contain important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, among other areas of interest. HAPCs happen to be afforded the same regulatory protection as EFH and do not banish activities from occurring in the area, such as fishing, snorkeling, swimming or surfing.
Necessary Fish Habitat is specified for all federally managed seafood under the MSA whereas Important Habitat is designated for the survival and recovery of species listed since threatened or endangered within the Endangered Species Act (ESA).|29| Critical demeure include areas occupied by the threatened or endangered kinds that include physical and scientific features that are essential to the conservation of the species.|30| Critical Habitat is designated as critical at the time a species is listed underneath the ESA.|31| EFH and Critical Habitat differ in terms of designation and rules, but they may overlap for certain species such as salmon.|32|
Environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures hidden the water surface, and aquatic community structures. These case are essential for fish and ecosystem health. The fundamental environment structure begins with gunk. Erosion is stabilized by simply submerged aquatic vegetation. You will find 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 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 prawn selected vegetated areas in salinities 15-25 ppt plus they would select vegetated areas over marsh edges after 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 provides hard complex vertical composition for attachment of a sponge, seaweed, and coral, which support a diverse reef seafood community.|35| This community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, various fin-fishes, alga, and sponges. Areas of compacted or sheered mud and sediment also are 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 can be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Features that affect soft starting in relation to organisms that make use of them include sediment grain size, salinity, dissolved oxygen and flow.
