Available in PDF, EPUB and Kindle. Book excerpt: Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.

Available in PDF, EPUB and Kindle. Book excerpt: Trophic interactions are critical drivers of ecosystem change and stability, yet are often excluded from fishery assessment models. For fisheries that are primarily dependent on a single prey species, replacing single species assessment models with multispecies models may improve population estimates while quantifying the impact of species interactions on fishery dynamics. In Lake Ontario, recreational salmonine fisheries, including Chinook Salmon (Oncorhynchus tshawytscha) and Lake Trout (Salvelinus namaycush), are heavily dependent on a single prey species, Alewife (Alosa pseudoharengus). My dissertation research focuses on assessing these predator-prey dynamics and then exploring how novel data streams could improve the assessment model. First, I developed a multispecies stock assessment model that jointly estimates the dynamics of Chinook Salmon, Lake Trout, and Alewife. I found that a risk assessment of future predator-prey dynamics indicated that recruitment of naturally reproduced Chinook Salmon could be a key driver of future fishery sustainability and additional data on the relative abundance of naturally reproduced fish could improve model estimates. Second, to address this data gap, I piloted a project to explore if parentage-based tagging could be an accurate monitoring program to provide data on the relative abundance of hatchery-origin and naturally reproduced Chinook Salmon. Third, I compared the resource-efficiency of parentage-based tagging to a suite of other mass marking techniques that have been used to differentiate hatchery-origin and naturally reproduced Chinook Salmon in Lake Ontario. Finally, I assessed the impact of a parentage-based tagging monitoring program on improving model estimates relative to expanding existing monitoring programs.
Download or read book Invasive Aquatic Species of Europe Distribution Impacts and Management written by Erkki Leppäkoski and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global scale of alien species invasions is becoming more and more evident in the beginning ofthe new millennium. Though the problem ofbiological invasions became a rapidly growing research area, there are large gaps still, both geographically and the matically, to be filled in the near future. This book is the first attempt to provide an overall picture of aquatic species invasions in Europe. Its geographical scope stretches from Irish waters in the west to Volga River and the Caspian Sea in the east, and from Mediterranean in the south up to the Arctic coast of Europe. Not all parts of the continent could be equally covered, as in some countries species invasions are not studied yet. The book tends to represent the array of all major European aquatic systems on the broadest geographical and ecological scope possible from fully saline seas, semi-enclosed brackish water bodies and coastallagoons to freshwater lakes, major river systems and waterways. The key objectives include the present status and impacts caused by non-native aquatic species in European waters. Please note that lengthy species lists submitted for publication and additional informa tion were put on the Internet, as the electronical version of these tables benefits from computer assisted search for data (http://www. ku. lt/nemo/EuroAquaInvaders. htm). Altogether more than 100 scientists from 24 countries have joined to synthesize the available information on bioinvasions. However, the book does not claim to be fully comprehensive.

Book excerpt: Fish accomplish most of their basic behaviors by swimming. Swimming is fundamental in a vast majority of fish species for avoiding predation, feeding, finding food, mating, migrating and finding optimal physical environments. Fish exhibit a wide variety of swimming patterns and behaviors. This treatise looks at fish swimming from the behavioral and
Download or read book A Framework for Multispecies Assessment and Management written by Anna Rindorf and published by Nordic Council of Ministers. This book was released on 2013-06-26 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes a framework that can be used to identify the most important trade-offs in ecosystem based fisheries management. The framework contains a description of how to identify the border between the science and policy domains, how to identify objectives and set goals for management, and how to communicate the management advice. Consultations with stakeholders showed that multi-species management advice needs to be precautionary, provide yields close to MSY, be in accordance with ecosystem constraints and be possible to communicate clearly to managers and policymakers. The use of the framework is demonstrated through examples from three different ecosystems: the Baltic Sea, the North Sea and the Barents Sea.
Download or read book Ecosystems of the Deep Oceans written by P.A. Tyler and published by Elsevier. This book was released on 2003-03-27 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment. Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.
Download or read book The State of World Highly Migratory Straddling and Other High Seas Fishery Resources and Associated Species written by Jean-Jacques Maguire and published by Food & Agriculture Org.. This book was released on 2006 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries for highly migratory species are important in all oceans and semi-enclosed seas, except for polar regions. Fisheries for straddling fish stocks are much more localised, primarily occurring in a few regions where continental shelves extend beyond the 200 miles Exclusive Economic Zone (EEZ), while most fisheries for other high seas fishery resources are deep-water fisheries. This publication examines issues relating to the stocks of these resources, including information on their state of exploitation. Findings include that about 30 percent of the stocks of highly migratory tuna and tuna-like species, more than half of highly migratory oceanic sharks and nearly two-thirds of the straddling stocks and the stocks of other high seas fishery resources are overexploited or depleted. Although the stocks concerned represent only a small fraction of the world fishery resources, they are key indicators of the state of an overwhelming part of the ocean ecosystem which appears to be more overexploited than EEZs.

This book was released on 2006-06-19 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an environmental-economic analysis of exploited ecosystems with a clear policy orientation. The study moves beyond traditional economic fishery analysis in two respects. First, several theoretical and numerical models are offered that combine economic and ecological descriptions of fisheries. Second, valuation and stakeholder concerns are addressed in empirical analyses employing both qualitative and quantitative approaches. The approaches, models and policy insights are sufficiently general and innovative to interest a broad audience.
