Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. Ersus. Congress in the 1996 changes to the Magnuson-Stevens Fishery Conservation and Management Act, or Magnuson-Stevens Act, as "those waters and substrate needed to fish for spawning, breeding, nourishing or growth to maturity. "|1| Implementing regulations clarified that oceans include all aquatic areas and their physical, chemical, and biological properties; substrate comes with the associated biological organizations that make these areas ideal for fish habitats, and the description and identification of EFH should include habitats used at any time during the species' life pattern.|2| EFH contains 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 details. EFH has been described for more than a 1, 000 managed variety to date.|4| The primary purpose of EFH regulations is always to minimize the adverse effects of fishing and non fishing impacts on EFH towards the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Take action was amended to establish a new requirements to identify and explain EFH to protect, conserve and enhance EFH for the main advantage of the fisheries.|5| The Magnuson-Stevens Act possesses jurisdiction over the management and conservation of marine seafood species. Federal agencies need to consult with NOAA Fisheries when their actions or activities may adversely affect environment identified by federal local fishery management councils or perhaps NOAA Fisheries as EFH.|6| On January 19, 1997, interim final rules were published in the Federal Register (Vol. 62, No . 244) which identify procedures for implementation with the EFH provisions of the Magnuson-Stevens Act.|7| These rules were amended simply by publication of final rules upon January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management program (FMP) amendment, and depth the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Has an effect on from certain fishing procedures and coastal and maritime development and may alter, harm, or destroy habitats necessary for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal organizations work together to minimize these hazards.|13| Congress has created councils to classify unfavorable influences on fishes in relation to types of fishing gear, coast developments and nonpoint and point source pollution, along with, evaluating how well each 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 newly managed species will also be identified.|14| FMPs must describe and identify EFH for the fishery, minimize to the extent practicable the adverse effects of fishing about EFH, and identify other 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 for the habitat of federally been able commercial and recreational the fishing industry.|16| Federal actions agencies which fund, support, or carry out activities that may adversely affect EFH are required to consult with NOAA Fisheries.|17| The federal actions agency must provide NOAA Fisheries with an examination of all actions or recommended actions authorized, funded, or undertaken by the agency which may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal actions agency with EFH Preservation recommendations.|19| These kinds 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 minimize the adverse effects of fishing gear and fishing activities on EFH as well.|22| In addition , NOAA Fisheries and the FMCs may touch upon and make recommendations to the state agency on their activities which may affect EFH.|23|
Most consultations are done in the NMFS regional offices: Increased Atlantic Regional Fisheries Office (GARFO), Southeast Regional Business office (SERO), West Coast Regional 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 necessary to consult with NMFS. EFH services are required if the federal government offers authorized, funded, or taken on part or all of a proposed activity, and if the action will adversely influence EFH.|24| Negatively affecting EFH includes immediate or indirect physical, chemical substance or biological alterations of the waters or substrate and loss of, or injury to types and their habitat, and other environment components, or reduction in the quality and/or quantity of EFH.
Natural environment areas of particular concern or HAPCs are considered high goal areas for conservation, administration, 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 an environment type that is/will get stressed by development;
will include a habitat type that is uncommon.|27|
Current HAPCs consist of important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, amongst other areas of interest. HAPCs are afforded the same regulatory safeguard as EFH and do not banish activities from occurring in the area, such as fishing, snorkeling, swimming or surfing.
Imperative Fish Habitat is designated for all federally managed fish under the MSA whereas Critical Habitat is designated pertaining to the survival and restoration of species listed because threatened or endangered underneath the Endangered Species Act (ESA).|29| Critical refuge include areas occupied by the threatened or endangered types that include physical and scientific features that are essential to the conservation of the species.|30| Critical Habitat is certainly designated as critical during the time a species is listed beneath the ESA.|31| EFH and Critical Habitat vary in terms of designation and rules, but they may overlap for many species such as salmon.|32|
Home 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 an environment structure begins with sediment. Erosion is stabilized by submerged aquatic vegetation. You will find two main types of bottoms, hard and delicate.|33| A study by Christensen at el. (2004) looked at three bottom environment types (vegetated marsh border, submerged aquatic vegetation, and shallow non-vegetated bottom) with regards to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the analysis showed that brown prawn selected vegetated areas in salinities 15-25 ppt and in addition they would select vegetated areas over marsh edges when they co-occurred. Finding the areas that had the highest abundance helped to identify EFH of teen brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom provides hard complex vertical framework for attachment of sponges, seaweed, and coral, which support a diverse reef seafood community.|35| This kind of community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, a number of fin-fishes, alga, and sponges. Areas of compacted or sheered mud and sediment are usually 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 may be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Qualities that affect soft starting in relation to organisms that employ them include sediment grain size, salinity, dissolved air and flow.
