Riverine Index Netting


Book Description

This manual represents the provincial standard for assessing fish populations and communities in medium to large non-wadable rivers in Ontario. The Riverine Index Netting (RIN) nets and the manual have been developed to efficiently catch small, large, and extra-large fishes in rivers. The nets can be used singly or in combination to gather fish community information. This instruction manual assumes that the user has sound knowledge and field experience in netting and sampling fishes. It is subdivided into sections on: gear description, pre-field activities, field procedures, post field activities, and data management. A hypothetical case study is given to illustrate how the Riverine Index Netting method can be employed at a hydro power development. Appendices are also provided on bathymetry mapping, aging structures, contaminant analysis, field forms, equipment list, and fish species codes.--Document.




Management Systems for Riverine Fisheries


Book Description

This paper is concerned specifically with the problems of river fisheries and associated management issues. It deals in particular with the scope for building on traditional practices, through the participation of traditional fishing communities, as a means of improving the quality of river fishery management. The paper reviews the most frequently encountered problems of riverine fisheries such as over-fishing due to population pressure or migration, and artifically induced environmental factors such as dams, pollution and deforestation. It lays stress on the importance of studying fishing communities, as well as strictly biological factors, and presents a four-stage analysis of the evolution of traditional riverine fisheries. Several undesirable consequences of this typical evolution, both on the resource itself and on traditional fishing communities, are identified and illustrated by case studies from the Amazon and the Zambesi. Certain types of traditional management strategies are examined and assessed for their future utility. The current ineffectiveness of many existing government river fisheries management policies is noted, either as a result of lack of resources or because they are inappropriate, often rooted in outdated colonial legislation. The lack of both limited access measures and of participation by local fishing communities are highlighted as major deficiencies. The paper concludes by linking these two features as crucial components of durable river management strategies for the future, although other possibilities for management are also reviewed and assessed. The paper contains a comprehensive bibliography for further reading.




Riverine Ecology Volume 1


Book Description

This book is part of a two-volume set that offers an innovative approach towards developing methods and tools for assigning conservation categories of threatened taxa and their conservation strategies by way of different phases of eco-restoration in the context of freshwater river systems of tropical bio-geographic zones. The set provides a considerable volume of research on the biodiversity component of river ecosystems, seasonal dynamics of physical chemical parameters, geo-hydrological properties, types, sources and modes of action of different types of pollution, river restoration strategies and methodologies for the ongoing ecological changes of river ecosystems. Volume 1 provides an in-depth analysis of different theories with international relevance pertaining to the functioning of river ecosystems, shaping their structure and contributing ecological services, and includes the principles of riverine ecology such as biogeochemical cycles, physiography, hydrogeology, and physico-chemical parameters. It covers the basic concepts and principles of water within riverine ecosystems, and the underlying ecological principles operating to ensure ecological stability and sustainability of the fluvial ecosystem. The book explains the ecofunctionality of different geo-morphological, geo-hydrological and physico-chemical factors and processes in changing time scales and spaces, with special emphasis on the tropical fresh water rivers in India.










Weathering and the Riverine Denudation of Continents


Book Description

In this monograph the authors present an overview of the state-of-the-art and use examples or case histories to illustrate the combined role of rock decay and rivers on continental denudation. The Earth’s surface dynamics would not be conceivable without the fundamental component of rock weathering and the subsequent transport of solid debris and dissolved components to the coastal ocean through riverine drainage pathways. In other words, continental wear away is highly dependent on the mechanisms that control mineral decay. Moreover, besides the significant role played by rivers in shaping the Earth’s outer skin, there is the important function that rivers perform in all geochemical cycles, mediating between the lithosphere, the hydrosphere, the biosphere and the hydrosphere. Drainage basins and the weathering of rocks that occur therein may be significant sources (or sinks) of carbon dioxide and, hence, play a significant role in affecting the Earth’s climate.




Biology of Perch


Book Description

The genus Perca includes only three species of fish, but they are ubiquitous and abundant in freshwater and brackish environments of the northern hemisphere, from North America to Europe and Asia. These species are important both ecologically and economically. In Biology of Perch, world-renowned specialists review and update the biology of these fi




Resilience and Riverine Landscapes


Book Description

Resilience and Riverine Landscapes presents contributed chapters from global experts in Riverine Landscapes, making it the most comprehensive reference available on the topic. The book explores why rivers are ideal landscapes to study resilience and why studying rivers from a resilience perspective is important for our biophysical understanding of these landscapes and for society. The book focuses on the biophysical character of resilience in riverine landscapes, providing an interdisciplinary perspective of the structure, function, and interactions of riverine landscapes and the ecosystems they contain. The editors conclude by proposing a research agenda for the future, emphasizing the need for transdisciplinary research across a range of spatial and temporal scales and research domains. - Presents the resilience of rivers with both a theoretical and applied focus - Includes case studies from a wide geographical base, allowing for a full range of viewpoints - Showcases how resilience is being incorporated into the study and management of riverine landscapes - Includes a transdisciplinary focus on riverine landscapes, from theory to applied, and from biophysical to social-ecological systems

Riverine Craft of the Vietnam Wars


Book Description

“Provides clear and succinct descriptions of the various craft used not only by American forces but those of the French and South Vietnamese Navy.” —Army Rumour Service (ARRSE) The ShipCraft series provides in-depth information about building and modifying model kits of famous warship types. Lavishly illustrated, each book takes the modeler through a brief history of the subject, highlighting differences between ships and changes in their appearance over their careers. This includes paint schemes and camouflage, featuring color profiles and highly detailed line drawings and scale plans. The modeling section reviews the strengths and weaknesses of available kits, lists commercial accessory sets for super-detailing of the subjects, and provides hints on modifying and improving the basic kit. This is followed by an extensive photographic gallery of selected high-quality models in a variety of scales, and the book concludes with a section on research references—books, monographs, large-scale plans and relevant websites. This volume is something of a departure for the series in covering a wide variety of the types, at first improvised and then purpose-built for the Brown Water conflict. Besides the well-known American involvement, the book also covers some of the craft used by the French in their earlier struggle with Vietnamese guerrillas. With its unparalleled level of visual information—paint schemes, models, line drawings and photographs—this book is simply the best reference for any modelmaker setting out to build one of these unusual craft. “Very well written . . . The author’s interest, knowledge and enthusiasm come through the content and make the title so appealing to the reader.” —Armorama
