Available in PDF, EPUB and Kindle. Book excerpt: Marine mammal depredation refers to the phenomenon of marine mammals partially or completely removing catch from fishing gear. Its results, which can affect the survival of wild dolphin populations, as well as damage gear or target fish, disturb fishing activities and generate economic losses for fishers, are a growing cause for concern in several Mediterranean and Black Sea fisheries. Depredation events often leave dolphins injured or snared in fishing nets and fishers with damaged nets and lower catch values. As a result, these interactions can create conflicts between dolphins and fishers, undermining efforts to improve the sustainability of fisheries and the conservation of vulnerable species. This review offers an overview of historical and current trends of depredation by marine mammals in the region, including information on the contiguous Atlantic area west of Gibraltar. The publication aims to assess and synthesize depredation records and describe ongoing projects on depredation in order to improve knowledge on key aspects of depredation, such as the fishing practices associated with depredation events, the economic fallout caused by marine mammal–fisheries interactions and the species and populations most involved in depredation. In the Mediterranean and the Black Sea, coastal fisheries often come into contact with cetaceans, especially bottlenose dolphins (Tursiops truncatus), common dolphins (Delphinus delphis) and harbour porpoises (Phocoena phocoena relicta). These species feature most prominently in the depredation records assessed and are the main research focuses of ongoing monitoring projects in the region. However, Mediterranean monk seals (Monachus monachus) are also responsible for depredation, especially in the eastern Mediterranean, and are the subject of their own short chapter in this review.

Book excerpt: The National Marine Fisheries Service (NMFS) developed the Atlantic Large Whale Take Reduction (ALWTR) plan to protect endangered large whales from entanglements in commercial fishing gear, which can cause injury or death. Because whales continued to die after the ALWTF plan went into effect, NMFS proposed revisions in 2005. The author of this book discusses these issues, as well as the Marine Mammal Protection Act (MMPA), which requires the NMFS to establish take reductions teams for certain marine mammals to develop measures to reduce their incidental takes. Other bills that specifically address marine mammal regulatory and management issues are examined as well. Furthermore, while some of these issues can be addressed administratively, in regulations proposed and promulgated by the National Marine Fisheries Service, the U.S. Fish and Wildlife Service, or the USDA Animal and Plant Health Inspection Service, others likely would require statutory change. This book lays out the range of issues likely to be raised during reauthorization debate, the reasons behind them, and possible proposals that could be offered to address these concerns. This book consists of public domain documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.

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.
