Essential Fish Habitat
Imperative Fish Habitat (EFH) was defined by the U. S. Congress in the 1996 changes to the Magnuson-Stevens Fishery Conservation and Management Act, or perhaps Magnuson-Stevens Act, as "those waters and substrate needed to fish for spawning, breeding, nourishing or growth to maturity. "|1| Putting into action regulations clarified that marine environments include all aquatic areas and their physical, chemical, and biological properties; substrate involves the associated biological neighborhoods that make these areas ideal for fish habitats, and the information and identification of EFH should include habitats used any time during the species' life circuit.|2| EFH includes all types of aquatic habitat, including 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 facts. EFH has been described for over a 1, 000 managed kinds to date.|4| The main purpose of EFH regulations is to minimize the adverse effects of fishing and non sport fishing impacts on EFH to the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Function was amended to establish a new requirements to identify and describe EFH to protect, conserve and enhance EFH for the advantage of the fisheries.|5| The Magnuson-Stevens Act has 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 habitat identified by federal regional fishery management councils or NOAA Fisheries as EFH.|6| On Dec 19, 1997, interim final rules were published inside the Federal Register (Vol. sixty two, No . 244) which designate procedures for implementation on the EFH provisions of the Magnuson-Stevens Act.|7| These kinds of rules were amended by simply publication of final rules in January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management strategy (FMP) amendment, and fine detail the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Influences from certain fishing practices and coastal and submarine development and may alter, harm, or destroy habitats essential for fish. NOAA Fisheries, the regional fishery management local authorities (FMCs), and other federal firms 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 nonpoint 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 types. As new FMPs are developed, EFH for recently managed species will also be described.|14| FMPs need to describe and identify EFH for the fishery, decrease to the extent practicable the adverse effects of fishing on EFH, and identify other 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 for the habitat of federally supervised commercial and recreational the fishing industry.|16| Federal action agencies which fund, licenses, or carry out activities that may adversely affect EFH must consult with NOAA Fisheries.|17| The federal action agency must provide NOAA Fisheries with an examination of all actions or recommended 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 Conservation recommendations.|19| These kinds of Conservation Recommendations provide information on how to prevent, minimize, mitigate, or balance those adverse effects.|20| Federal action agencies must provide a written explanation to NOAA Fisheries if any of these recommendations have not been followed.|21| NOAA Fisheries must also include measures to minimize the adverse effects of reef fishing gear and fishing activities 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 Workplace (SERO), West Coast Local Office (WCRO), Alaska Regional Office (AKRO), and Pacific 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 consultation services are required if the federal government features authorized, funded, or taken on part or all of a proposed activity, and if the action will adversely have an effect on EFH.|24| Adversely affecting EFH includes direct or indirect physical, chemical substance or biological alterations with the waters or substrate and loss of, or injury to species and their habitat, and other environment components, or reduction from the quality and/or quantity of EFH.
Natural environment areas of particular concern or perhaps HAPCs are considered high top priority areas for conservation, supervision, and research.|26| HAPCs are subsets of EFH that merit special attention because they meet by least one of the following 4 criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a habitat type that is/will become stressed by development;
include a habitat type that is rare.|27|
Current HAPCs involve important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, amongst other areas of interest. HAPCs happen to be afforded the same regulatory coverage as EFH and do not exclude activities from occurring in the area, such as fishing, diving, swimming or surfing.
Essential Fish Habitat is specified for all federally managed fish under the MSA whereas Essential Habitat is designated meant for the survival and restoration of species listed as threatened or endangered beneath the Endangered Species Act (ESA).|29| Critical habitats include areas occupied by threatened or endangered variety that include physical and neurological features that are essential to the conservation of the species.|30| Critical Habitat is designated as critical during the time a species is listed beneath the ESA.|31| EFH and Critical Habitat are very different in terms of designation and regulations, but they may overlap for sure species such as salmon.|32|
Natural environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures base the water surface, and marine community structures. These case are essential for fish and ecosystem health. The fundamental home structure begins with yeast sediment. Erosion is stabilized by submerged aquatic vegetation. You will find two main types of bottoms, hard and delicate.|33| A study simply by Christensen at el. (2004) looked at three bottom an environment types (vegetated marsh advantage, submerged aquatic vegetation, and shallow non-vegetated bottom) pertaining to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the analysis showed that brown shrimp 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 teenage brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom delivers hard complex vertical framework for attachment of a dry sponge, seaweed, and coral, which in turn support a diverse reef fish community.|35| This kind of 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 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 level in relation to organisms that make use of them include sediment grain size, salinity, dissolved air and flow.
