Book Description
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.

Languages : en
Pages : 190
Book Description
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

Size-based assessment of data-limited inland fish stocks – Review and applications
Author: Shephard, S., Valbo-Jorgensen, J., Abadía, J., Baigún, C., Doria, C.R.C., Fabré, N.N., Isaac, V.J., Ngor, P.B., Ruffino, M.L., Funge-Smith, S.J.

Pages : 75
Book Description
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.

The Freshwater Fishes of Suriname
Author: Jan H.A. Mol
Publisher: BRILL
ISBN: 9004207651
Category : Science
Languages : en
Pages : 899
Book Description
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.

Biodiversity
Author: Oscar Grillo
Publisher: BoD – Books on Demand
ISBN: 9535113151
Category : Science
Languages : en
Pages : 382
Book Description
The current world biodiversity consists of an inestimable amount of living forms, that at all levels, from genes to biomes, from individuals to populations, from species to communities, are in constant pursuit of the best strategies to react to the natural and anthropic environmental changes. The arrangement of new and dynamic ecosystems balanced by the formation and the vanishing of species, is the direct consequence of these changes. This book contains comprehensive overviews and original studies focused on ecological and ecosystem functioning studies, hazards and conservation management, assessment of environmental variables affecting species diversity, also considering species richness and distribution, in order to identify the best management strategies to face and solve the conservation problems.

Migration of Freshwater Fishes
Author: Martyn Lucas
Publisher: John Wiley & Sons
ISBN: 0470999640
Category : Technology & Engineering
Languages : en
Pages : 440
Book Description
Recent studies have increasingly demonstrated the widespread existence of spatio-temporal variations in the abundance and distribution of species of freshwater fishes, previously assumed not to move between habitats. These movements are often on a seasonal or ontogenetic basis, for spawning, feeding and refuge, and in many cases are fundamental for the successful completion of lifecycles. This important book provides a single source for a range of previously widely dispersed information on these movements of fish in fresh waters, covering potamodromous fishes as well as the more familiar diadromous species, worldwide. Contents include full descriptions of types of migration and spatial behaviour, the stimulus and capacity for fish to migrate, the effects of climate on patterns of migratory behaviour, a taxonomic analysis (mostly by family) of freshwater fish migration, methods for studying migration, and details of the impacts of man's activities on freshwater fish migration. Migration of Freshwater Fishes provides an excellent and comprehensive reference to which the river manager, biologist or student can now refer to obtain information, advice and current opinion on the migratory behaviour of most taxonomic groups of fishes occurring in fresh water. University libraries and aquatic research stations should also have copies of this essential reference book on their shelves. Well-known international authors. Of great commercial importance to fisheries and professional angling bodies. Draws together much new information in one place. Detailed review of world wide migratory behaviour for most groups of freshwater fishes. Pure and applied relevance, for academics, fisheries scientists, river managers and conservationists. This comprehensive book includes 67 tables and figures and over 1,400 references.
