The Amazon Basin's rivers, estuaries and tributaries are home to as many as 1000 species of catfish. In this work, two scientists offer a natural history of the Amazon giant catfish and its central place as a source of food and income within the ecology and economy of the Amazon Basin. While focusing primarily on two species of giant catfish - known locally as Dourada and Piramutaba - the authors also present illustrated accounts of 13 distinct large fish. Their research yields strong statistical data and field observations that illustrate the catfishes' extensive migratory range and presents solid evidence of animal species requiring or using a large part of the basin for their ecological needs.

The star of the Animal Planet's River Monsters and author of the bestselling companion book shares a meditation on fishing--and life. In his previous book, Jeremy Wade memorably recounted his adventures in pursuit of fish of staggering proportions and terrifying demeanor: goliath tigerfish from the Congo, arapaima from the Amazon, "giant devil catfish" from the Himalayan foothills, and more. Now, the greatest angling explorer of his generation returns to delight readers with a book of a different sort, the book he was always destined to write -- the distillation of a life spent fishing. As Jeremy's catches attract increasing attention, many people ask him how they can improve their own fishing results. This book is his reply: part science, part art, and part elusive something else -- which is within every angler's ability to develop. Along the way you will learn when to let instinct override logic, which details are vital and which may be irrelevant, and how a "non result" can be a result. Thoughtful and funny, brimming with wisdom and, above all, adventure, these are pitch-perfect reflections that anyone who has ever fished will identify with, for ultimately they touch on the simple, fundamental principles that apply to all angling -- and to life.

Landscape Evolution of Continental-Scale River Systems: A Case Study of North America's Pre-Pleistocene Bell River Basin provides a detailed case study and complete analysis of this continental-scale North American paleo-river system. The book uses detrital zircon provenance data to link incision of the Grand Canyon to deposition of its erosional products in a giant drowned delta in the Labrador Sea, in the context of sedimentary source-to-sink processes and Plio-Pleistocene continental drainage changes. The case study describes the tectonic changes in this continental-scale paleo-river system, with global implications, and contrasts this system to other continental-scale river systems around the world. This book is a valuable reference for postgraduate students, academics and researchers in the fields of geology, fluvial geomorphology and other geosciences. Readers will be able to use this detailed case study to better understand the implications for how active tectonics of headwaters regions influence delta deposition in continental-scale river systems around the world. - Details the landscape evolution of a continental-scale paleo-river system using detrital zircon geochronology with fluvial processes - Provides a multidisciplinary case study with applications to other continental-scale river systems around the world - Compares and contrasts the Bell river to the Amazon and uses these examples as analogs to discuss other systems

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.

With some 480 currently known fresh- and brackish-water fish species, Suriname has a rich inland fish fauna that is related to the most diverse freshwater fish fauna on planet Earth, i.e. that of the Amazon River. Interest in the freshwater fishes of Suriname by naturalists and scientists extends back over more than two centuries. Suriname is undoubtedly the site of origin of the oldest extant preserved specimens of South American fishes and 19 Surinamese fish species were described and figured by Linnaeus. Building on ichthyological studies initiated in the 1960s by the Brokopondo Project, this book provides an introduction to the freshwater fish fauna of Suriname, including identification keys, photographs of the species and descriptions of their habitats, that should be especially useful to decision makers, conservation biologists, aquarium hobbyists and eco-tourists.
