Download or read book Broodstock Management and Egg and Larval Quality written by Niall R. Bromage and published by Wiley-Blackwell. This book was released on 1995-02-17 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, the supply of eggs and fry is one of the major constraints on future aquaculture development. For the majority of farmed species, production is totally dependent on harvesting of broodstocks or seed from wild populations At present we know little about the control of reproduction of most farmed finfish nor of the detailed nutrient, metabolic and husbandry requirements of the broodstock or the ways in which they might be managed to optimize seed production and improve the quality of eggs and larvae. Newer technologies such as ploidy and gender manipulation, induced spawning and cryopreservation are coming to the forefront of modern broodstock management and all of these topics are considered, in detail, in this new text. Broodstock Management and Egg and Larval Quality has been written as a standard text for commercial practitioners and students of aquaculture, fish biology and fisheries and provides a comprehensive review of current and future methods of broodstock and hatchery management. The range of marine and freshwater tropical and temperate finfish species considered, together with contributions from many of the world's most eminent fish biologists, provide comprehensive and international coverage of this increasingly important area of aquaculture.
Download or read book Climate Change Implications for Fisheries and Aquaculture written by K. L. Cochrane and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the current scientific knowledge available on climate change implications for fisheries and aquaculture is provided through three technical papers that were presented and discussed during the Expert Workshop on Climate Change Implications for Fisheries and Aquaculture (Rome, 7-9 April 2008). A summary of the workshop outcomes as well as key messages on impacts of climate change on aquatic ecosystems and on fisheries- and aquaculture-based livelihoods are provided in the introduction of this Technical Paper. The first paper reviews the physical and ecological impacts of climate change relevant to marine and inland capture fisheries and aquaculture. The paper begins with a review of the physical impacts of climate change on marine and freshwater systems and then connects these changes with observed effects on fish production processes. It also outlines a series of scenarios of climate change impacts on fish production and ecosystems through case studies in different regions and ecosystems. The second paper tackles the consequences of climate change impacts on fisheries and their dependent communities. It analyses the exposure, sensitivity and vulnerability of fisheries to climate change and presents examples of adaptive mechanisms currently used in the sector. The contribution of fisheries to greenhouse gas emissions is addressed and examples of mitigation strategies are given. The role of public policy and institutions in promoting climate change adaptation and mitigation is also explored. Finally, the third paper addresses the impacts of climate change on aquaculture. It provides an overview of the current food fish and aquaculture production and a synthesis of existing studies on climate change effects on aquaculture and fisheries. The paper focuses on the direct and indirect impacts of climate change on aquaculture, in terms of biodiversity, fish disease and fishmeal. Contribution of aquaculture to climate change is addressed (carbon emission and carbon sequestration), as well as possible adaptation and mitigation measures that could be implemented.

Download or read book Early Life History and Recruitment in Fish Populations written by R.C. Chambers and published by Springer Science & Business Media. This book was released on 1997-07-31 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.

Download or read book Salmon Without Rivers written by Jim Lichatowich and published by . This book was released on 1999-08 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.
Download or read book Adaptive management of fisheries in response to climate change written by Bahri, T., Vasconcellos, M., Welch, D.J., Johnson, J., Perry, R.I., Ma, X. & Sharma, R. and published by Food & Agriculture Org.. This book was released on 2021-02-01 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report aims to accelerate climate change adaptation implementation in fisheries management throughout the world. It showcases how flexibility can be introduced in the fisheries management cycle in order to foster adaptation, strengthen the resilience of fisheries, reduce their vulnerability to climate change, and enable managers to respond in a timely manner to the projected changes in the dynamics of marine resources and ecosystems. The publication includes a set of good practices for climate-adaptive fisheries management that have proven their effectiveness and can be adapted to different contexts, providing a range of options for stakeholders including the fishing industry, fishery managers, policymakers and others involved in decision-making. These good practices were linked to one or more of the three common climate-related impacts on fisheries resources: distributional change; productivity change; and species composition change. Therefore, these three impacts can serve as practical entry points to guide decision-makers in identifying good practice adaptation measures suitable for their local contexts. These good practices are based upon transferable experiences and lessons learned from the thirteen case studies across the globe and hopefully will contribute to greater uptake and implementation of climate-adaptive fisheries management measures on the ground.

Download or read book How to be a Quantitative Ecologist written by Jason Matthiopoulos and published by John Wiley & Sons. This book was released on 2011-04-12 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological research is becoming increasingly quantitative, yet students often opt out of courses in mathematics and statistics, unwittingly limiting their ability to carry out research in the future. This textbook provides a practical introduction to quantitative ecology for students and practitioners who have realised that they need this opportunity. The text is addressed to readers who haven't used mathematics since school, who were perhaps more confused than enlightened by their undergraduate lectures in statistics and who have never used a computer for much more than word processing and data entry. From this starting point, it slowly but surely instils an understanding of mathematics, statistics and programming, sufficient for initiating research in ecology. The book’s practical value is enhanced by extensive use of biological examples and the computer language R for graphics, programming and data analysis. Key Features: Provides a complete introduction to mathematics statistics and computing for ecologists. Presents a wealth of ecological examples demonstrating the applied relevance of abstract mathematical concepts, showing how a little technique can go a long way in answering interesting ecological questions. Covers elementary topics, including the rules of algebra, logarithms, geometry, calculus, descriptive statistics, probability, hypothesis testing and linear regression. Explores more advanced topics including fractals, non-linear dynamical systems, likelihood and Bayesian estimation, generalised linear, mixed and additive models, and multivariate statistics. R boxes provide step-by-step recipes for implementing the graphical and numerical techniques outlined in each section. How to be a Quantitative Ecologist provides a comprehensive introduction to mathematics, statistics and computing and is the ideal textbook for late undergraduate and postgraduate courses in environmental biology. "With a book like this, there is no excuse for people to be afraid of maths, and to be ignorant of what it can do." —Professor Tim Benton, Faculty of Biological Sciences, University of Leeds, UK
