Assessment of data-limited fish stocks is a rapidly evolving topic in marine fisheries, and is supported by an increasing focus on the socio-economic and ecological importance of small-scale fisheries. The challenges in such systems can be compounded in inland fisheries, which are often complex, spatially dispersed and difficult to monitor. This publication reviews the application of empirical indicators and simple size-based models usually used in marine fisheries, but also applicable in inland systems. It presents case study applications for important fisheries in the Amazon River (Brazil), Tonlé Sap River (Cambodia), Paraná River (Argentina) and Lago Bayano (Panama). These studies consider issues including spatial separation of life-history stages, strong modality in population size structure, and fishing gear selectivity. Local scientific experts interpreted trends in stock state. Empirical indicators showed strong decline in size structure and relative abundance for one of the four assessed Tonlé Sap stocks. The length-based spawning potential ratio model suggested that two of the three assessed Amazon Goliath catfish stocks, and the sábalo stock in the Paraná River, were below sustainable spawning potential ratio reference points. The Lago Bayano tilapia stock appeared healthy. The review concludes that data-limited assessment methods developed for marine stocks may provide guidance for the sustainable management of important target species in inland fisheries. The methods tested are probably less applicable in non-selective fisheries where small species are preferred, or in river fisheries with extreme dependence on flood pulses. Important considerations are species life history and spatial distribution, environmental variability, and fishery sampling strategy.

This book takes a multi-disciplinary and critical look at what has changed over the last ten years in one of the world's most important and dynamic ecosystems, the Amazon floodplain or várzea. It also looks forward, assessing the trends that will determine the fate of environments and people of the várzea over the next ten years and providing crucial information that is needed to formulate strategies for confronting these looming realities.

This book is a product of Brazilian Academy of Sciences Study Group about water issue. The water cycle was addressed based on an integrated point of view, aiming at joining technological and ecological solutions and integrating quantitative and qualitative aspects of this important environmental asset. Issues such as the water resources management and irrigated agriculture, water and health, water and economy, conservation and reuse as management tools, water in the Brazilian semi arid, water in Amazon, urbanization and water resources, education for the sustainability of water resources, groundwater, availability, pollution and eutrophication of water and science, technology and innovation are of the utmost importance for this exact moment in Brazil, and particularly to the State of Sao Paulo. Addressing these issues will undoubtedly contribute towards a sustainable management of water resources trough the coordinated work of different fields of science, progressing a systemic view about water, that would then finally allow management professionals the possibility of an integral action in anticipating problems and thus anticipate solutions.

This review presents summary information on 45 river and great lake basins of the world, which support inland fisheries. The information presented is drawn from published information in peer-reviewed journals as well as grey literature. Each basin summary is presented in a common format, covering the description of the fishery, estimates of catch and numbers of people engaged in the fishery, important biodiversity features and threats to the fishery. An analysis of the replacement costs of inland fish of the basin is also presented. This is expressed in terms of the water, land and greenhouse gas footprint that would arise if the inland fish that are currently produced had to be replaced with other forms of food (such as aquaculture fish, livestock or field crops).

Wildlife management specialists and landscape ecologists offer a new perspective on the important intersection of these fields in the twenty-first century. It's been clear for decades that landscape-level patterns and processes, along with the tenets and tools of landscape ecology, are vitally important in understanding wildlife-habitat relationships and sustaining wildlife populations. Today, significant shifts in the spatial scale of extractive, agricultural, ranching, and urban land uses are upon us, making it more important than ever before to connect wildlife management and landscape ecology. Landscape ecologists must understand the constraints that wildlife managers face and be able to use that knowledge to translate their work into more practical applications. Wildlife managers, for their part, can benefit greatly from becoming comfortable with the vocabulary, conceptual processes, and perspectives of landscape ecologists. In Wildlife Management and Landscapes, the foremost landscape ecology experts and wildlife management specialists come together to discuss the emerging role of landscape concepts in habitat management. Their contributions • make the case that a landscape perspective is necessary to address management questions • translate concepts in landscape ecology to wildlife management • explain why studying some important habitat-wildlife relationships is still inherently difficult • explore the dynamic and heterogeneous structure of natural systems • reveal why factors such as soil, hydrology, fire, grazing, and timber harvest lead to uncertainty in management decisions • explain matching scale between population processes and management • discuss limitations to management across jurisdictional boundaries and balancing objectives of private landowners and management agencies • offer practical ideas for improving communication between professionals • outline the impediments that limit a full union of landscape ecology and wildlife management Using concrete examples of modern conservation challenges that range from oil and gas development to agriculture and urbanization, the volume posits that shifts in conservation funding from a hunter constituent base to other sources will bring a dramatic change in the way we manage wildlife. Explicating the foundational similarity of wildlife management and landscape ecology, Wildlife and Landscapes builds crucial bridges between theoretical and practical applications.

One of the main goals in fisheries governance is to promote viability and sustainability in small-scale fishing communities. This is not an easy task given external and internal pressure, including environmental change and competition with other economic sectors searching for development in the coastal region. A comprehensive understanding of small-scale fisheries in their own context, and from a regional perspective, is an important step in supporting the implementation of the Voluntary Guidelines on Securing Sustainable Small-Scale Fisheries (SSF Guidelines). This book contributes to the global effort by offering knowledge, insights and lessons about small-scale fisheries in Latin America and the Caribbean. The 20 case studies included in the book make explicit the various dimensions that are intrinsic to small-scale fisheries in the region, and identify conditions and situations that affect the wellbeing of fishing communities. The book offers insights regarding the challenges faced by small-scale fisheries in the region, and, aligning with the objectives of the SSF Guidelines, provides lessons and experiences about how to make small-scale fishing communities viable while maintaining sustainable fisheries. This important book illustrates the complexity, diversity, and dynamics of small-scale fisheries in the Latin American and Caribbean region and presents experiences, tools, and approaches to lead towards sustainable and viable fisheries. The reader will gain a new understanding on the range of actions, approaches, and information needed for their successful management. John F. Caddy, International Fisheries Expert This book, prepared by the Too Big To Ignore partnership, constitutes a very valuable resource for policy makers, fisheries scientists, non-governmental organizations, civil society organizations, and fishing communities interested in putting in place sound management strategies, research, and actions to contribute to the sustainability of small-scale fisheries and food security in Latin America and the Caribbean region.
