Book excerpt: North Atlantic right whales (Eubalaena glacialis) are among the most critically endangered cetacean species in the world. Despite having protected status, both internationally and in Canadian waters, the right whale population that frequents Canadian waters remains at low abundance, with an estimated population of around 325 individuals (EC 2006). It has been estimated that at least thirty percent of right whale deaths result from their interaction with human activities, and entanglement in fishing gear is a significant cause for known injury and mortality (Knowlton and Kraus 2001). This report has identified the different gear types and fisheries that right whales encounter in Scotia-Fundy region, as well as the potential they pose for entanglement. Commercial landings data for the time series between 1999 and 2005 inclusive were used to assess the spatial and temporal distribution of fishing activity. These fishery distributions were compared to the patterns of right whale aggregation in Scotia-Fundy waters in order to estimate the potential for right whale/gear interaction among the different gear types/fisheries over time and space. Of all the gears that right whales encounter in their summer habitat, the groundfish gillnet, groundfish hook and line, and crab trap fisheries pose the greatest potential for entanglement. These gear types are relatively more likely to lead to entanglement because (1) these are the most active fisheries in Scotia-Fundy during the period of right whale aggregation, and (2) the design of the gears and their methods of deployment lend themselves to possible entanglements. The results of this study may be used to advise industry and management on actions that would minimize the risk of entanglement to right whales, while correspondingly minimizing any disruption of the commercial fisheries in the Scotia-Fundy region

This book was released on 2021-06-23 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potentially harmful contact between fisheries and marine vulnerable species represents a global conservation issue and efforts to mitigate the negative repercussions of these interactions belong in strategies for ensuring the sustainability of fisheries. This literature review offers a survey of mitigation measures and techniques that have been developed and tested around the world, aiming to address both the incidental catch of highly mobile species – specifically, cetaceans, seabirds, sharks and rays, and sea turtles – and depredation caused by dolphins. Based on research detailed in over 300 documents, including peer-reviewed publications, reports from international organizations and papers available on the internet, most of the mitigation techniques illustrated are still under development, with only a few already adopted through legislation. The selected mitigation measures are grouped by main types of fishing gear – gillnets and trammel nets, longlines and lines, trawls, purse seines, traps and pots – and further subdivided according to which of the four main groups of vulnerable species – cetaceans, seabirds, sharks and rays, or sea turtles – they are designed to protect. Preventive and curative approaches covering both technical measures (gear modifications, strategies, as well as acoustic, visual, magnetic and chemosensory deterrents) and management measures are described.

Available in PDF, EPUB and Kindle. Book excerpt: Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined. An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.

Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

The United States Coast Pilot consists of a series of nautical books that cover a variety of information important to navigators of coastal and intracoastal waters and the Great Lakes. Issued in nine volumes, they contain supplemental information that is difficult to portray on a nautical chart. Topics in the Coast Pilot include channel descriptions, anchorages, bridge and cable clearances, currents, tide and water levels, prominent features, pilotage, towage, weather, ice conditions, wharf descriptions, dangers, routes, traffic separation schemes, small-craft facilities, and Federal regulations applicable to navigation. Coast Pilot 1 covers the coasts of Maine, New Hampshire, and part of Massachusetts, from West Quoddy Head in Maine to Provincetown in Massachusetts. Major ports are at Portsmouth, NH and Boston, MA. Coast Pilot 2 covers the Atlantic coast from Cape Cod to Sandy Hook, embracing part of the Massachusetts coast and all of the coasts of Rhode Island, Connecticut, and New York. Coast Pilot 3 covers the Atlantic coast from Sandy Hook to Cape Henry, including the New Jersey Coast, Delaware Bay, Philadelphia, the Delaware - Maryland - Virginia coast, and the Chesapeake Bay. Coast Pilot 4 covers the Atlantic coast of the United States from Cape Henry to Key West. Coast Pilot 5 covers the Gulf of Mexico from Key West, FL to the Rio Grande. This area is generally low and mostly sandy, presenting no marked natural features to the mariner approaching from seaward. so covers Puerto Rico and the Virgin Islands. Coast Pilot 6 covers the Great Lakes system, including Lakes Ontario, Erie, Huron, Michigan, and Superior, their connecting waters, and the St. Lawrence River. Coast Pilot 7 covers the rugged United States coast of California, Oregon and Washington, between Mexico on the south and Canadas British Columbia on the north. Coast Pilot 7 also includes Hawaii and other United States territories in the South Pacific. Coast Pilot 8 covers the panhandle section of Alaska between the south boundary and Cape Spencer. In this volume, general ocean coastline is only 250 nautical miles, but tidal shoreline totals 11,085 miles. Coast Pilot 9 deals with the Pacific and Arctic coasts of Alaska from Cape Spencer to the Beaufort Sea. General ocean coastline totals 5,520 nautical miles, and tidal shoreline totals 18,377 miles. Coast Pilot 10 consists of excerpts taken from other coast pilots with reference to the Intercoastal Waterway

Available in PDF, EPUB and Kindle. Book excerpt: Global Change in Marine Systems analyses and appraises societal and governing responses to change affecting marine social and ecological systems around the world. Acknowledging the stakes – local societies that depend on marine systems for food, livelihoods and wellbeing can suffer great hardship – this book highlights and explains similarities and distinctions between successful and unsuccessful responses. The book presents an analytical framework (‘I-ADApT’) that enables decision-makers to consider possible responses to global change based on experiences elsewhere. Here an international group of researchers from the natural and social sciences apply the ‘I-ADApT’ framework to twenty enlightening case studies, covering a wide range of marine systems challenged by critical global change issues around the world. The innovative research presented here guides marine system researchers, policymakers, decision-makers and practitioners in responding to global change in a timely and appropriate manner. It will appeal to students and researchers interested in environmental studies, natural resources, marine resources, environmental sociology, sustainability, and climate change.
