This book was released on 2003-10-22 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Mammals: Fisheries, Tourism and Management Issues brings together contributions from 68 leading scientists from 12 countries to provide a comprehensive, up-to-date review on the way we manage our interactions with whales, dolphins, seals and dugongs. The book examines how we have fared conserving the world’s marine mammal populations, with a focus on the key issues of fisheries and tourism. From a unique southern hemisphere perspective, the authors consider how science informs the culling debate, how wild fisheries and aquaculture interact with marine mammal populations and how we might manage the effects of whale, dolphin and seal watching industries. The authors also address other issues such as the way in which ethics, genetics, acoustics, ecosystem models and pollution influence the management and conservation of marine mammals. Marine Mammals is an invaluable and accessible resource for all those involved with marine mammals, including scientists, managers, policy makers, industry representatives and students. Winner of a 2004 Whitley Award.
Download or read book An Updated World Review of Interactions Between Marine Mammals and Fisheries written by Simon P. Northridge and published by Food & Agriculture Org.. This book was released on 1991 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent information on marine mammal - fishery interactions is reviewed. A species by species approach is taken for each of the major marine fishing areas of the world. Most recent studies have been devoted to the accidental entanglement or mortality of marine mammals in fishing operations. Several species or populations of marine mammal may be threatened with extinction or severe depletion from such interactions. Most of the fisheries involved are gillnet fisheries. Relatively few recent studies have addressed the possible competitive interactions between marine mammals and fisheries for food and fishery resources.

Download or read book Marine Mammals written by Peter G.H. Evans and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 629 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in marine mammals has increased dramatically in the last few decades, as evidenced by the number of books, scientific papers, and conferences devoted to these animals. Nowadays, a conference on marine mammals can attract between one and two thousand scientists from around the world. This upsurge of interest has resulted in a body of knowledge which, in many cases, has identified major conservation problems facing particular species. At the same time, this knowledge and the associated activities of environmental organisations have served to introduce marine mammals to a receptive public, to the extent that they are now perceived by many as the living icons of biodiversity conservation. Much of the impetus for the current interest in marine mammal conservation comes from "Save the Whale" campaigns started in the 1960s by environmental groups around the world, in response to declining whale populations after over-exploitation by humans. This public pressure led to an international moratorium on whaling recommended in 1972 by the United Nations Conference on the Human Environment in Stockholm, Sweden, and eventually adopted by the International Whaling Commission ten years later. This moratorium largely holds sway to this day, and further protective measures have included the delimitation of extensive areas of the Indian Ocean (1979) and Southern Ocean (1994) as whale sanctuaries.

Download or read book Ocean Recovery written by Ray Hilborn and published by Oxford University Press, USA. This book was released on 2019-06-27 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, the scientific and popular media have been bombarded by gloom and doom stories of the future of fisheries, the status of fish stocks, and the impact of fishing on marine ecosystems. Dozens of certification and labeling schemes have emerged to advise consumers on what seafood is sustainable. In recent years, an opposing narrative has emerged emphasizing the success of fisheries management in many places, the increasing abundance of fish stocks in those places, and the prescription for sustainable fisheries. However, there has been no comprehensive survey of what really constitutes sustainability in fisheries, fish stock status, success and failures of management, and consideration of the impacts of fishing on marine ecosystems. This book will explore very different perspectives on sustainability, and bring together the data from a large number of studies to show where fish stocks are increasing, where they are declining, the consequences of alternative fisheries management regimes, and what is known about a range of fisheries issues such as the impacts of trawling on marine ecosystems. Ocean Recovery is aimed principally at a general audience that is already interested in fisheries but seeks both a deeper understanding of what is known about specific issues and an impartial presentation of all the data rather than selected examples used to justify a particular perspective or agenda. It will also appeal to the scientific community eager to know more about marine fisheries and fishing data, and serve as the basis for graduate seminars on the sustainability of natural resources.
Download or read book Marine Mammals the Evolving Human Factor written by Giuseppe Notarbartolo di Sciara and published by Springer Nature. This book was released on 2022-06-08 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seventh volume in the series “Ethology and Behavioral Ecology of Marine Mammals” describes aspects of the often-complex relationship between humans and marine mammals. From a primeval condition of occasional predators, during the last century humans have become a major factor negatively affecting the status of most marine mammals through over-hunting, habitat encroachment and environmental degradation. This has led to the extirpation of many marine mammal populations and even to the extinction of species. However, in parallel to this destructive drive, since antiquity humanity has been influenced by a strong fascination for marine mammals, which contributes today to an increased human appreciation of the natural world admixed with widespread concern for its degrading condition. The special status occupied by marine mammals in human imagination and affection stands in stark contrast with the current predicament of many populations still threatened by the doings of Homo sapiens: a condition emblematic of the relationship of humanity with nature, and key to understanding where humanity is heading.

This book was released on 2017-05-04 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.
