Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. H. Congress in the 1996 amendments to the Magnuson-Stevens Fishery Preservation 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 includes the associated biological organizations that make these areas suited to fish habitats, and the description and identification of EFH should include habitats used anytime during the species' life circuit.|2| EFH comes with all types of aquatic habitat, such as wetlands, coral reefs, fine sand, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management local authorities to designate EFH making use of the best available scientific data. EFH has been described for more than a 1, 000 managed types to date.|4| The primary purpose of EFH regulations is to minimize the adverse effects of fishing and non sportfishing 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 benefit 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 ever their actions or actions may adversely affect habitat identified by federal territorial fishery management councils or perhaps NOAA Fisheries as EFH.|6| On Dec 19, 1997, interim final rules were published in the Federal Register (Vol. over 60, No . 244) which indicate procedures for implementation of the EFH provisions of the Magnuson-Stevens Act.|7| These types of rules were amended by publication of final rules upon January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management plan (FMP) amendment, and aspect the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Impacts from certain fishing routines and coastal and submarine development and may alter, harm, or destroy habitats essential for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal companies work together to minimize these threats.|13| Congress has created councils to classify unfavorable effects on fishes in relation to types of fishing gear, coastal developments and nonpoint and point source pollution, and also, evaluating how well every single fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed variety. As new FMPs happen to be developed, EFH for newly managed species will also be defined.|14| FMPs need to describe and identify EFH for the fishery, lessen to the extent practicable the adverse effects of fishing about EFH, and identify additional 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 fisheries.|16| Federal action 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 suggested actions authorized, funded, or undertaken by the agency that may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal actions agency with EFH Conservation recommendations.|19| These Conservation Recommendations provide information on keep away from, minimize, mitigate, or balance those adverse effects.|20| Federal action agencies need to provide a written explanation to NOAA Fisheries if any of these recommendations have not been implemented.|21| NOAA Fisheries must also include measures to reduce the adverse effects of reef fishing gear and fishing actions on EFH as well.|22| In addition , NOAA Fisheries and the FMCs may touch upon and make recommendations to the state agency on their actions which may affect EFH.|23|
Most consultations are done in the NMFS regional offices: Higher Atlantic Regional Fisheries Office (GARFO), Southeast Regional Workplace (SERO), West Coast Regional Office (WCRO), Alaska Territorial Office (AKRO), and Pacific Islands Regional Office (PIRO). National consultations spanning multiple regions can be done at NOAA Fisheries Headquarters.
State agencies and private landowners are not instructed to consult with NMFS. EFH services are required if the federal government has authorized, funded, or carried out part or all of a proposed activity, and if the action will adversely have an impact on EFH.|24| Adversely affecting EFH includes direct or indirect physical, chemical substance or biological alterations from the waters or substrate and loss of, or injury to variety and their habitat, and other environment components, or reduction in the quality and/or quantity of EFH.
Habitat areas of particular concern or perhaps HAPCs are considered high goal areas for conservation, administration, 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 environmental function;
are sensitive to environmental degradation;
include a habitat type that is/will end up being stressed by development;
add a habitat type that is uncommon.|27|
Current HAPCs involve important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, among other areas of interest. HAPCs will be afforded the same regulatory security as EFH and do not rule out activities from occurring inside the area, such as fishing, snorkeling, swimming or surfing.
Necessary Fish Habitat is chosen for all federally managed seafood under the MSA whereas Critical Habitat is designated pertaining to the survival and restoration of species listed seeing that threatened or endangered beneath the Endangered Species Act (ESA).|29| Critical demeure include areas occupied by the threatened or endangered variety that include physical and biological features that are essential to the conservation of the species.|30| Critical Habitat is definitely designated as critical at that time a species is listed underneath the ESA.|31| EFH and Critical Habitat will vary in terms of designation and legislation, but they may overlap for several species such as salmon.|32|
Habitat characteristics include sediment type, type of bottoms (sand, silt and clay), structures base the water surface, and aquatic community structures. These demeure are essential for fish and ecosystem health. The fundamental home structure begins with crud. Erosion is stabilized simply 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 home types (vegetated marsh border, submerged aquatic vegetation, and shallow non-vegetated bottom) in relation to juvenile brown shrimp (Farfantepenaeus aztecus). The results from the study showed that brown prawn selected vegetated areas in salinities 15-25 ppt and in addition they would select vegetated areas over marsh edges every time 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 supplies hard complex vertical framework for attachment of a dry sponge, seaweed, and coral, which often support a diverse reef fish community.|35| This 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 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 are often primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Features that affect soft lower side in relation to organisms that make use of them include sediment grain size, salinity, dissolved o2 and flow.
