Essential Fish Habitat
Fundamental Fish Habitat (EFH) was defined by the U. S. Congress in the 1996 changes to the Magnuson-Stevens Fishery Conservation and Management Act, or Magnuson-Stevens Act, as "those waters and substrate necessary to fish for spawning, breeding, nourishing 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 areas 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 pattern.|2| EFH involves all types of aquatic habitat, including wetlands, coral reefs, yellow sand, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management councils to designate EFH making use of the best available scientific data. EFH has been described for over a 1, 000 managed types to date.|4| The primary purpose of EFH regulations is usually to minimize the adverse effects of fishing and non angling impacts on EFH to the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Action was amended to establish a brand 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 need to consult with NOAA Fisheries once their actions or actions may adversely affect home identified by federal local fishery management councils or NOAA Fisheries as EFH.|6| On Dec 19, 1997, interim last rules were published in the Federal Register (Vol. 62, No . 244) which specify procedures for implementation of the EFH provisions of the Magnuson-Stevens Act.|7| These rules were amended simply by publication of final rules about January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management strategy (FMP) amendment, and details the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Impacts from certain fishing techniques and coastal and underwater development and may alter, damage, or destroy habitats necessary for fish. NOAA Fisheries, the regional fishery management local authorities (FMCs), and other federal firms work together to minimize these dangers.|13| Congress has established 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 varieties. As new FMPs are developed, EFH for recently managed species will also be described.|14| FMPs must describe and identify EFH for the fishery, minimize to the extent practicable the adverse effects of fishing upon EFH, and identify additional 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 within the habitat of federally handled commercial and recreational the fishing industry.|16| Federal action agencies which fund, grant, 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 evaluation of all actions or offered actions authorized, funded, or perhaps undertaken by the agency that may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal action agency with EFH Preservation recommendations.|19| These kinds of Conservation Recommendations provide information on keep away from, minimize, mitigate, or balance out those adverse effects.|20| Federal action agencies must provide a written explanation to NOAA Fisheries if some of these recommendations have not been followed.|21| NOAA Fisheries must also include measures to reduce the adverse effects of sport fishing gear and fishing actions on EFH as well.|22| In addition , NOAA The fishing industry and the FMCs may discuss and make recommendations to the state agency on their activities which may affect EFH.|23|
Most consultations are done inside the NMFS regional offices: Increased Atlantic Regional Fisheries Workplace (GARFO), Southeast Regional Business 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 organizations and private landowners are not forced to consult with NMFS. EFH services are required if the federal government provides authorized, funded, or done part or all of a proposed activity, and if the action will adversely affect EFH.|24| Negatively affecting EFH includes direct or indirect physical, chemical substance or biological alterations in the waters or substrate and loss of, or injury to kinds and their habitat, and other environment components, or reduction on the quality and/or quantity of EFH.
Home areas of particular concern or perhaps HAPCs are considered high priority areas for conservation, managing, and research.|26| HAPCs are subsets of EFH that merit 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 get stressed by development;
include a habitat type that is uncommon.|27|
Current HAPCs incorporate important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, amongst other areas of interest. HAPCs will be afforded the same regulatory security as EFH and do not exclude activities from occurring inside the area, such as fishing, diving, swimming or surfing.
Essential Fish Habitat is specified for all federally managed seafood under the MSA whereas Crucial Habitat is designated pertaining to the survival and restoration of species listed since threatened or endangered under the Endangered Species Act (ESA).|29| Critical habitats include areas occupied by threatened or endangered kinds that include physical and natural features that are essential to the conservation of the species.|30| Critical Habitat can be designated as critical during the time a species is listed underneath the ESA.|31| EFH and Critical Habitat differ in terms of designation and control, but they may overlap for sure species such as salmon.|32|
An environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures hidden the water surface, and aquatic community structures. These habitats are essential for fish and ecosystem health. The fundamental home structure begins with residue. Erosion is stabilized simply by submerged aquatic vegetation. You will find two main types of bottoms, hard and soft.|33| A study by simply Christensen at el. (2004) looked at three bottom home types (vegetated marsh border, submerged aquatic vegetation, and shallow non-vegetated bottom) pertaining to 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 teenage brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom gives hard complex vertical structure for attachment of sponges, seaweed, and coral, which in turn support a diverse reef seafood community.|35| This community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, a variety of fin-fishes, alga, and sponges. 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 are often primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Qualities that affect soft lower part in relation to organisms that utilize them include sediment feed size, salinity, dissolved oxygen and flow.
