Essential Fish Habitat
Essential Fish Habitat (EFH) was defined by the U. Ersus. Congress in the 1996 amendments to the Magnuson-Stevens Fishery Resource efficiency and Management Act, or perhaps Magnuson-Stevens Act, as "those waters and substrate important to fish for spawning, breeding, feeding or growth to maturity. "|1| Utilizing regulations clarified that lakes and rivers include all aquatic areas and their physical, chemical, and biological properties; substrate incorporates the associated biological areas that make these areas suited to fish habitats, and the explanation and identification of EFH should include habitats used without notice during the species' life cycle.|2| EFH involves all types of aquatic habitat, including wetlands, coral reefs, sand, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management local authorities to designate EFH using the best available scientific information. EFH has been described for more than a 1, 000 managed types 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 Act was amended to establish a brand new requirements to identify and identify EFH to protect, conserve and enhance EFH for the main advantage of the fisheries.|5| The Magnuson-Stevens Act has jurisdiction over the management and conservation of marine seafood species. Federal agencies must consult with NOAA Fisheries the moment their actions or activities may adversely affect habitat identified by federal territorial fishery management councils or perhaps NOAA Fisheries as EFH.|6| On 12 19, 1997, interim last rules were published in the Federal Register (Vol. 62, No . 244) which designate procedures for implementation of the EFH provisions of the Magnuson-Stevens Act.|7| These kinds of rules were amended by simply publication of final rules upon January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management system (FMP) amendment, and details the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Influences from certain fishing techniques and coastal and maritime development and may alter, damage, or destroy habitats necessary for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal businesses work together to minimize these hazards.|13| Congress has established councils to classify unfavorable effects on fishes in relation to types of fishing gear, coastal developments and nonpoint and point source pollution, as well as, evaluating how well every single fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed types. As new FMPs will be developed, EFH for recently managed species will also be defined.|14| FMPs need to describe and identify EFH for the fishery, minimize 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 suggest ways federal agencies may avoid or minimize the adverse effects of their actions around the habitat of federally handled 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 actions agency must provide NOAA Fisheries with an diagnosis of all actions or proposed 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 Conservation recommendations.|19| These types of Conservation Recommendations provide information on steer clear of, minimize, mitigate, or balance out those adverse effects.|20| Federal action agencies need to provide a written explanation to NOAA Fisheries if some of these recommendations have not been implemented.|21| NOAA The fishing industry 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 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: Increased Atlantic Regional Fisheries Business office (GARFO), Southeast Regional 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 businesses and private landowners are not forced to consult with NMFS. EFH discussions 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 impact EFH.|24| Detrimentally affecting EFH includes direct or indirect physical, substance or biological alterations on the waters or substrate and loss of, or injury to species and their habitat, and other ecosystem components, or reduction in the quality and/or quantity of EFH.
An environment areas of particular concern or HAPCs are considered high concern areas for conservation, administration, and research.|26| HAPCs are subsets of EFH that merit work because they meet for least one of the following 5 criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a natural environment type that is/will come to be stressed by development;
include a habitat type that is exceptional.|27|
Current HAPCs include important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, amongst other areas of interest. HAPCs are afforded the same regulatory coverage as EFH and do not banish activities from occurring in the area, such as fishing, diving, swimming or surfing.
Imperative Fish Habitat is specified for all federally managed seafood under the MSA whereas Vital Habitat is designated to get the survival and recovery of species listed while threatened or endangered under the Endangered Species Act (ESA).|29| Critical refuge include areas occupied by the threatened or endangered kinds that include physical and organic 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 underneath the ESA.|31| EFH and Critical Habitat will vary in terms of designation and control, but they may overlap for several 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 g?te are essential for fish and ecosystem health. The fundamental home structure begins with gunk. Erosion is stabilized by submerged aquatic vegetation. You will discover two main types of bottoms, hard and very soft.|33| A study simply by Christensen at el. (2004) looked at three bottom natural environment types (vegetated marsh advantage, submerged aquatic vegetation, and shallow non-vegetated bottom) with regards to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the study showed that brown shrimp selected vegetated areas in salinities 15-25 ppt and in addition 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 structure for attachment of a 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, many different fin-fishes, alga, and a dry sponge. Areas of compacted or sheered mud and sediment are 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. Characteristics that affect soft lower side in relation to organisms that employ them include sediment hemp size, salinity, dissolved air and flow.
