Essential Fish Habitat
Necessary 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 Magnuson-Stevens Act, as "those waters and substrate essential to fish for spawning, breeding, nourishing or growth to maturity. "|1| Putting into action regulations clarified that oceans include all aquatic areas and their physical, chemical, and biological properties; substrate includes the associated biological areas that make these areas ideal for fish habitats, and the information and identification of EFH should include habitats used anytime during the species' life circuit.|2| EFH contains all types of aquatic habitat, just like wetlands, coral reefs, fine 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 variety to date.|4| The key purpose of EFH regulations is usually to minimize the adverse effects of fishing and non sport fishing impacts on EFH to the maximum extent practicable.
In 1996, the Magnuson-Stevens Fishery Conservation and Management Act was amended to establish a fresh requirements to identify and describe EFH to protect, conserve and enhance EFH for the main benefit of the fisheries.|5| The Magnuson-Stevens Act provides jurisdiction over the management and conservation of marine seafood species. Federal agencies must consult with NOAA Fisheries when their actions or activities may adversely affect environment identified by federal local fishery management councils or perhaps NOAA Fisheries as EFH.|6| On 12 , 19, 1997, interim final rules were published inside the Federal Register (Vol. over 60, No . 244) which indicate procedures for implementation on the EFH provisions of the Magnuson-Stevens Act.|7| These kinds of rules were amended simply by publication of final rules in January 17, 2002 (Vol. 67, No . 12).|8| he rules, in two subparts, address requirements for fishery management approach (FMP) amendment, and detail the coordination, consultation, and recommendation requirements of the Magnuson-Stevens Act.
Has an effect on from certain fishing procedures and coastal and maritime development and may alter, harm, or destroy habitats important for fish. NOAA Fisheries, the regional fishery management local authorities (FMCs), and other federal agencies work together to minimize these dangers.|13| Congress has established councils to classify unfavorable affects on fishes in relation to types of fishing gear, seaside developments and non-point and point source pollution, along with, evaluating how well every single 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 newly managed species will also be identified.|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 other 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 around the habitat of federally handled commercial and recreational fisheries.|16| Federal actions agencies which fund, permit, 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 analysis of all actions or offered actions authorized, funded, or perhaps undertaken by the agency which may adversely affect EFH.|18| Then NOAA Fisheries will provide the federal action agency with EFH Resource efficiency recommendations.|19| These kinds of Conservation Recommendations provide information on how to prevent, 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 adopted.|21| NOAA The fishing industry must also include measures to minimize the adverse effects of sportfishing gear and fishing activities on EFH as well.|22| In addition , NOAA Fisheries and the FMCs may discuss and make recommendations to the state agency on their actions which may affect EFH.|23|
Most consultations are done inside the NMFS regional offices: Higher Atlantic Regional Fisheries Business office (GARFO), Southeast Regional Business office (SERO), West Coast Regional Office (WCRO), Alaska Regional Office (AKRO), and Ocean 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 meetings are required if the federal government has authorized, funded, or done part or all of a proposed activity, and if the action will adversely influence EFH.|24| Detrimentally affecting EFH includes immediate or indirect physical, chemical or biological alterations with the waters or substrate and loss of, or injury to kinds and their habitat, and other environment 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, control, and research.|26| HAPCs are subsets of EFH that merit attention because they meet for least one of the following four criteria:
provide important environmental function;
are sensitive to environmental degradation;
include a natural environment type that is/will come to be stressed by development;
incorporate a habitat type that is rare.|27|
Current HAPCs consist of important habitats like estuaries, canopy kelp, corals, seagrass, and rocky reefs, among other areas of interest. HAPCs will be afforded the same regulatory coverage as EFH and do not don't include activities from occurring inside the area, such as fishing, snorkeling, swimming or surfing.
Essential Fish Habitat is designated for all federally managed fish under the MSA whereas Important Habitat is designated pertaining to the survival and restoration of species listed because threatened or endangered beneath the Endangered Species Act (ESA).|29| Critical g?te include areas occupied by the threatened or endangered types that include physical and natural features that are essential to the conservation of the species.|30| Critical Habitat is usually designated as critical during the time a species is listed beneath the ESA.|31| EFH and Critical Habitat are different 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 marine community structures. These habitats are essential for fish and ecosystem health. The fundamental environment structure begins with crud. Erosion is stabilized by submerged aquatic vegetation. There are two main types of bottoms, hard and delicate.|33| A study by Christensen at el. (2004) looked at three bottom environment types (vegetated marsh advantage, submerged aquatic vegetation, and shallow non-vegetated bottom) in terms of juvenile brown shrimp (Farfantepenaeus aztecus). The results from the analysis 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 teenage brown shrimp.|34|
Hard bottom also known as coral reefs or live bottom gives hard complex vertical composition for attachment of a sponge, seaweed, and coral, which often support a diverse reef seafood 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 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 make use of them include sediment wheat size, salinity, dissolved o2 and flow.
