This book was released on 2013 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Under the Endangered Species Act (ESA), the U.S. Fish and Wildlife Service (USFWS) listed the southwest Alaska distinct population segment (SWDPS) of the northern sea otter as threatened in 2005. In 2006, National Marine Fisheries Service (NMFS) and the USFWS consulted on the effects of the groundfish, crab, and scallop fisheries on the SWDPS of the northern sea otter. The consultation concluded with a determination that the fisheries were not likely to adversely affect the SWDPS. In 2009, the USFWS designated critical habitat of the SWDPS of the northern sea otter, and consequently, NMFS is requesting reinitiating consultation under section 7 of the ESA. The fisheries analyzed are: Alaska groundfish fisheries as authorized by the Fishery Management Plan for Groundfish of the Bering Sea and Aleutian Islands Management Area, the Fishery Management Plan for Groundfish of the Gulf of Alaska, and the State of Alaska parallel groundfish fisheries in State of Alaska waters; Alaska king and Tanner crab fisheries as authorized by the Fishery Management Plan for Bering Sea/Aleutian Islands King and Tanner Crabs; Alaska salmon fisheries as authorized by the Fishery Management Plan for the Salmon Fisheries in the EEZ off Alaska; Alaska scallop fisheries as authorized by the Fishery Management Plan for the Scallop Fishery off Alaska. In addition, this consultation pertains to the effect on SWDPS of northern sea otters and their critical habitat from Pacific halibut fisheries in U.S. Convention waters off Alaska within International Pacific Halibut Commission regulatory areas 2C, 3A, 3B, 4A, 4B, 4C, 4D, and 4E. In this analysis, the potential direct and indirect impacts of federal fisheries and fisheries managed by the State of Alaska with federal coordination or oversight are evaluated in the context of the SWDPS of the northern sea otter and its designated critical habitat. The best available commercial information is used to describe the potential impacts of the fisheries on sea otters and on their designated critical habitat. Cumulative effects of non-federal actions also are examined. Effects of the fisheries on sea otters and their critical habitat can be either direct or indirect effects. Direct effects include the incidental take of sea otters in fishing gear and the disturbance of sea otters by fishing vessels. The potential for incidental takes of SWDPS of northern sea otters in the fisheries analyzed in this biological assessment is discountable. Potential indirect effect on the SWDPS of northern sea otters or on their critical habitat is due to impacts on prey resources. Prey species are varied and include urchins, crabs, and bivalves, which may be directly or indirectly harvested in one or more target fisheries. Primary Constituent Elements (PCEs) for critical habitat include food, water, air, light, minerals, or other nutritional or physiological requirements (73 FR 76457, December 16, 2008). Fishery indirect effects on prey would be primarily from the direct or incidental harvest of these species or effects on the habitat that support these prey resources. Fishery catch data within critical habitat, with particular attention to incidental catch of potential sea otter prey and fishery activities that may impact habitat supporting prey, are provided. This information is used to determine the potential impact of the fisheries on prey resources of the SWDPS of the northern sea otter and the potential impacts of the fisheries on the PCEs provided by designated critical habitat. The impacts of the fisheries are so small as to not have a measureable effect on the SWDPS of the northern sea otter, their prey, or designated critical habitat. The effects are therefore insignificant."--Executive summary.

Book excerpt: "This document is an environmental assessment/regulatory impact review/initial regulatory flexibility analysis analyzing proposed management measures that would apply to the directed groundfish fishery in the Gulf of Alaska (GOA). The measures under consideration would set Pacific halibut prohibited species catch (PSC) limits in Federal regulation, decrease the annual GOA halibut PSC limits for trawl and hook-and-line groundfish fisheries, and implement additional halibut PSC management measures for the GOA groundfish fisheries. The purpose of this action is to minimize halibut bycatch in the GOA groundfish fisheries to the extent practicable and to promote the Jong-term conservation and abundance of halibut for all users of the resource. The proposed action is not expected to have significant impacts on the human environment"--Cover letter summary.

This book was released on 2019 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex ecological interactions such as predation and competition play an important role in shaping the structure and function of marine communities. In fact, these processes can have greater impacts than those related to fishing. We assessed ecological interactions among economically important fishes in the Gulf of Alaska – a large marine ecosystem that has recently undergone considerable shifts in community composition. Specifically, we developed an index of predation for Walleye Pollock (Gadus chalcogrammus) to examine spatiotemporal changes in consumption, quantify portfolio effects, and better understand diversity-stability relationships within the demersal food web. We also evaluated the potential for competition between two important pollock predators, Arrowtooth Flounder (Atheresthes stomias) and Pacific Halibut (Hippoglossus stenolepis). We found highly variable predation intensity on Gulf of Alaska pollock. The combination of a single dominant predator and synchronous consumption dynamics indicated strong top-down control in the region. Spatial heterogeneity, however, may offset trophic instability at the basin scale. Assessments of resource partitioning provided little indication for competition between Arrowtooth Flounder and Pacific Halibut of similar lengths. Morphological differences between the two flatfish predators prompted an exploration into whether our conclusions about resource partitioning were dependent upon the size metric used. From this study, we found a relatively early onset of piscivory for Arrowtooth Flounder. Relationships between predator size and prey size also suggested gape limitation among Pacific Halibut sampled. Trophic niche separation was more pronounced for fishes with larger gapes, indicating greater potential for competition among smaller Arrowtooth Flounder and Pacific Halibut in Southeast Alaska. Reexamining basin-scale relationships between spatial and dietary overlap according to gape size would further elucidate the effects an increasing Arrowtooth Flounder population has had on changes in Pacific Halibut size-at-age. Results from this dissertation improve our understanding about the impacts of complex ecological interactions on population and community dynamics, and how those interactions may change in time, space, and under different environmental conditions.

Available in PDF, EPUB and Kindle. Book excerpt: "This Environmental Assessment/Regulatory Impact Review/Final Regulatory Flexibility Analysis analyzes Amendment 34 which amends the Bering Sea and Aleutian Islands Crab Rationali zation Program to exempt additional recipients of crab quota share from Gulf of Alaska Pacific cod and pollock harvest limits, called sideboards. Sideboards apply to some vessels and license limitation program licenses that are used to participate in these fisheries. The North Pacific Fishery Management Council determined that these recipients demonstrated a sufficient level of historical participation in Gulf of Alaska Pacific cod or pollock fisheries and should be exempt from the Gulf of Alaska Pacific cod and pollock sideboards. This action is necessary to give these recipients an opportunity to participate in the Gulf of Alaska Pacific cod and pollock fisheries at historical levels. This final rule revises regulations governing exemptions from and calculations of sideboard harvest limits in the Gulf of Alaska Pacific cod and pollock fisheries and revises Tables 17 and 18 that establish the 20II - 2012 Gulf of Alaska ground fish harvest sideboard limits. To fully implement Amendment 34 NMFS will reissue Federal fisheries permits and license limitation program licenses to all participants that are affected by the action."--Cover letter; Portfolio comprised of three related PDF documents digitized and organized by: NOAA Office of Program Planning and Integration (PPI) National Environmental Policy Act (NEPA) staff.

This book was released on 2013 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: This EA/RIR/IRFA analyzes the impacts of four alternatives to close specific areas of the Central Gulf of Alaska Regulatory Area (Central GOA) to the use of trawl gear and pot gear or as a suboption, in lieu of a closure to require additional observer coverage in these areas. Based on the Council's recommendation, NMFS determined that increased observer coverage in specific areas of the Central GOA would interfere with the goals and objectives of the restructured observer program and is not necessary. The intent to improve Tanner crab bycatch information is addressed in the restructured observer program, which was implemented in 2013. The Council's preferred alternative is to close a portion of Marmot Bay northeast of Kodiak Island to the use of trawl gear, except for the use of pelagic trawl gear to target pollock. The Council's preferred alternative for the Marmot Bay Protection Area trawl closure will be combined with the Council's preferred alternative requiring modified nonpelagic trawl gear to be used when targeting flatfish in Central Gulf of Alaska Regulatory Area to form a suite of management measures for the protection and conservation of Tanner crab and reduce the potential for adverse impacts by nonpelagic gear on benthic habitat.
