Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. H. Congress in the 1996 amendments to the Magnuson-Stevens Fishery Conservation 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 seas include all aquatic areas and their physical, chemical, and biological properties; substrate contains the associated biological neighborhoods that make these areas well suited for fish habitats, and the explanation and identification of EFH should include habitats used at any time during the species' life spiral.|2| EFH involves all types of aquatic habitat, just like wetlands, coral reefs, mud, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management local authorities to designate EFH using the best available scientific facts. EFH has been described for more than 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 towards the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Function was amended to establish a new requirements to identify and explain EFH to protect, conserve and enhance EFH for the advantage of the fisheries.|5| The Magnuson-Stevens Act offers jurisdiction over the management and conservation of marine seafood species. Federal agencies must consult with NOAA Fisheries the moment their actions or actions may adversely affect natural 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. sixty two, No . 244) which identify procedures for implementation in the EFH provisions of the Magnuson-Stevens Act.|7| These kinds of rules were amended by publication of final rules about January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management program (FMP) amendment, and details the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Impacts from certain fishing techniques and coastal and marine development and may alter, damage, or destroy habitats important 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, 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 newly managed species will also be identified.|14| FMPs need to describe and identify EFH for the fishery, reduce to the extent practicable the adverse effects of fishing upon EFH, and identify different actions to encourage the conservation and enhancement of EFH.
Through consultations, NOAA Fisheries can recommend ways federal agencies can easily avoid or minimize the adverse effects of their actions for the habitat of federally managed commercial and recreational the fishing industry.|16| Federal actions agencies which fund, permit, or carry out activities which may adversely affect EFH are required to consult with NOAA Fisheries.|17| The federal actions agency must provide NOAA Fisheries with an evaluation of all actions or offered actions authorized, funded, or perhaps undertaken by the agency which may adversely affect EFH.|18| Then NOAA The fishing industry 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 offset 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 reduce the adverse effects of sport 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: Better Atlantic Regional Fisheries Workplace (GARFO), Southeast Regional Business office (SERO), West Coast Territorial Office (WCRO), Alaska Local Office (AKRO), and Ocean Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State companies and private landowners are not instructed to consult with NMFS. EFH consultation services are required if the federal government has authorized, funded, or done part or all of a proposed activity, and if the action will adversely impact EFH.|24| Adversely affecting EFH includes immediate or indirect physical, substance or biological alterations on the waters or substrate and loss of, or injury to variety and their habitat, and other environment components, or reduction from the quality and/or quantity of EFH.
Home areas of particular concern or HAPCs are considered high concern areas for conservation, control, and research.|26| HAPCs are subsets of EFH that merit special attention because they meet for least one of the following 5 criteria:
provide important ecological function;
are sensitive to environmental degradation;
include a an environment type that is/will be stressed by development;
incorporate a habitat type that is exceptional.|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 security as EFH and do not banish activities from occurring in the area, such as fishing, snorkeling, swimming or surfing.
Necessary Fish Habitat is designated for all federally managed fish under the MSA whereas Vital Habitat is designated for the survival and recovery of species listed since threatened or endangered beneath the Endangered Species Act (ESA).|29| Critical case include areas occupied by threatened or endangered variety that include physical and biological features that are essential to the conservation of the species.|30| Critical Habitat can be designated as critical at 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 several species such as salmon.|32|
Natural 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 natural environment structure begins with sediment. Erosion is stabilized simply by submerged aquatic vegetation. You will find two main types of bottoms, hard and gentle.|33| A study simply by Christensen at el. (2004) looked at three bottom habitat types (vegetated marsh border, submerged aquatic vegetation, and shallow non-vegetated bottom) regarding juvenile brown shrimp (Farfantepenaeus aztecus). The results from the analysis showed that brown prawn selected vegetated areas in salinities 15-25 ppt and 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 teen brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom gives hard complex vertical framework for attachment of a dry sponge, seaweed, and coral, which support a diverse reef seafood community.|35| This community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, many different 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 underside are not protected even though they could be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Characteristics that affect soft lower side in relation to organisms that make use of them include sediment hemp size, salinity, dissolved oxygen and flow.
