Essential Fish Habitat
Necessary Fish Habitat (EFH) was defined by the U. S. Congress in the 1996 amendments to the Magnuson-Stevens Fishery Conservation and Management Act, or Magnuson-Stevens Act, as "those waters and substrate needed to fish for spawning, breeding, nourishing or growth to maturity. "|1| Implementing regulations clarified that lakes and rivers include all aquatic areas and their physical, chemical, and biological properties; substrate includes the associated biological neighborhoods that make these areas suited to fish habitats, and the description and identification of EFH should include habitats used whenever you want during the species' life spiral.|2| EFH comes with all types of aquatic habitat, including wetlands, coral reefs, mud, seagrasses, and rivers.|3|
NOAA Fisheries works with the regional fishery management councils to designate EFH making use of the best available scientific details. EFH has been described for more than a 1, 000 managed types to date.|4| The main purpose of EFH regulations should be 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 new requirements to identify and explain 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 fish species. Federal agencies must consult with NOAA Fisheries the moment their actions or activities may adversely affect habitat identified by federal regional fishery management councils or perhaps NOAA Fisheries as EFH.|6| On December 19, 1997, interim last rules were published inside the Federal Register (Vol. over 60, No . 244) which stipulate procedures for implementation with the EFH provisions of the Magnuson-Stevens Act.|7| These rules were amended simply by publication of final rules on January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management system (FMP) amendment, and detail the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Influences from certain fishing procedures and coastal and submarine development and may alter, damage, or destroy habitats important for fish. NOAA Fisheries, the regional fishery management councils (FMCs), and other federal agencies work together to minimize these hazards.|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, evaluating how well every fishery is managed. The FMCs, with assistance from NOAA Fisheries, has delineated EFH for federally managed kinds. As new FMPs will be developed, EFH for recently managed species will also be identified.|14| FMPs must describe and identify EFH for the fishery, minimize to the extent practicable the adverse effects of fishing upon 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 within the habitat of federally been able commercial and recreational the fishing industry.|16| Federal action agencies which fund, license, or carry out activities that may adversely affect EFH have to consult with NOAA Fisheries.|17| The federal action agency must provide NOAA Fisheries with an examination of all actions or proposed 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 Resource efficiency recommendations.|19| These types of Conservation Recommendations provide information on keep away from, minimize, mitigate, or offset 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 The fishing industry must also include measures to minimize the adverse effects of sport 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 inside the NMFS regional offices: Greater Atlantic Regional Fisheries Workplace (GARFO), Southeast Regional Business office (SERO), West Coast Territorial 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 agencies and private landowners are not necessary to consult with NMFS. EFH discussions are required if the federal government offers authorized, funded, or undertaken part or all of a proposed activity, and if the action will adversely affect EFH.|24| Adversely affecting EFH includes direct or indirect physical, substance or biological alterations with the waters or substrate and loss of, or injury to varieties and their habitat, and other environment components, or reduction with the quality and/or quantity of EFH.
Habitat areas of particular concern or perhaps HAPCs are considered high concern areas for conservation, management, and research.|26| HAPCs are subsets of EFH that merit work because they meet for least one of the following some criteria:
provide important environmental function;
are sensitive to environmental degradation;
include a natural environment type that is/will be stressed by development;
add a habitat type that is unusual.|27|
Current HAPCs consist of important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, between other areas of interest. HAPCs will be afforded the same regulatory safeguard as EFH and do not banish activities from occurring in the area, such as fishing, snorkeling, swimming or surfing.
Essential Fish Habitat is selected for all federally managed seafood under the MSA whereas Vital Habitat is designated for the survival and recovery of species listed while threatened or endangered underneath the Endangered Species Act (ESA).|29| Critical habitats include areas occupied by threatened or endangered variety that include physical and scientific features that are essential to the conservation of the species.|30| Critical Habitat is certainly designated as critical at the moment a species is listed under the ESA.|31| EFH and Critical Habitat vary in terms of designation and regulations, but they may overlap for many species such as salmon.|32|
Natural environment characteristics include sediment type, type of bottoms (sand, silt and clay), structures underlying the water surface, and aquatic community structures. These case are essential for fish and ecosystem health. The fundamental natural environment structure begins with yeast sediment. Erosion is stabilized by submerged aquatic vegetation. You will find two main types of bottoms, hard and smooth.|33| A study by Christensen at el. (2004) looked at three bottom home types (vegetated marsh advantage, submerged aquatic vegetation, and shallow non-vegetated bottom) regarding juvenile brown shrimp (Farfantepenaeus aztecus). The results from the study 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 juvenile brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom supplies hard complex vertical structure for attachment of sponges, seaweed, and coral, which support a diverse reef fish community.|35| This community can comprise invertebra, coral, hard coral, bryozoans, ploychaete worms, tunicates, a range of fin-fishes, alga, and a dry sponge. Areas of compacted or sheered mud and sediment can also be 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 might be primary nursery areas, anadromous fish spawning areas, and anadromous nursery areas. Characteristics that affect soft bottom level in relation to organisms that utilize them include sediment feed size, salinity, dissolved fresh air and flow.
