Available in PDF, EPUB and Kindle. Book excerpt: Low-level river crossings, including culverts, are important for delivering a range of valuable socioeconomic services, including transportation and hydrological control. These structures are also known to have negative impacts on freshwater river system morphology and ecology, including the blockage of upstream fish passage, particularly small-body-mass fish species. Given the enormous environmental problems created by road crossings, new hydraulic engineering guidelines are proposed for fish-friendly multi-cell box culvert designs. The focus of these guidelines is on smooth box culverts without appurtenance, with a novel approach based upon three basic concepts: (I) the culvert design is optimized for fish passage for small to medium water discharges, and for flood capacity for larger discharges, (II) low-velocity zones are provided along the wetted perimeter in the culvert barrel, and quantified in terms of a fraction of the wetted flow area where the local longitudinal velocity is less than a characteristic fish speed linked to swimming performances of targeted fish species, and (III) the culvert barrel is smooth, without any other form of boundary treatment and appurtenance. The present monograph develops a number of practical considerations, in particular relevant to box culvert operations for less-than-design discharges. It is argued that upstream fish passage capabilities would imply a revised approach to maintenance, in part linked to the targeted fish species. This reference work is authored for civil and environmental engineers, as well as biology and ecology scientists interested in culvert design. While the book is aimed to professionals, the material is also lectured in postgraduate courses and in professional short courses.

Download or read book Behavior of Marine Fishes written by Pingguo He and published by John Wiley & Sons. This book was released on 2011-06-09 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: BEHAVIOR OF MARINE FISHES BEHAVIOR OF MARINE FISHES: Capture Processes and Conservation Challenges Understanding fish behavior in relation to capture processes in marine fisheries is of fundamental importance to reducing bycatch and discards, and to enhancing marine fisheries conservation efforts. A thorough understanding of this allows commercial fishers to more effectively capture target species while reducing the catch of unwanted species. Behavior of Marine Fishes: Capture Processes and Conservation Challenges provides the reader with principles, patterns, and characteristics on fish behavior and fish capture processes using several types of important commercial fishing gears. The book also highlights conservation challenges facing the marine capture fisheries in efforts to maintain sustainable use of marine resources and to reduce negative impacts to the marine ecosystem. This volume, with contributions from leading applied fish behaviorists and fishing gear technologists from around the world, will be a valuable reference for researchers, fishing gear technologists, fisheries managers, students, and conservationists. SPECIAL FEATURES: Synthesis of current research and valuable knowledge that will help reduce bycatch and discards in commercial fisheries Review of basic fish behavioral principles and patterns and their relation to capture methods and conservation efforts Contributions from leading international applied fish behaviorists and fishing gear technologists

Download or read book The Evolutionary Basis of Strabismus and Nystagmus in Children written by Michael C. Brodsky and published by Springer Nature. This book was released on 2021-05-12 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is a comprehensive collection and discussion of scientific essays that define the pathogenesis of common forms of pediatric strabismus and nystagmus in terms of their common evolutionary mechanisms. The goal of this book is to assemble these essays, to provide a definitive source for current clinicians to use along with follow up comments to help direct future scientific research in the field of pediatric ophthalmology. This book includes 20 original essays written by Michael C. Brodsky which mechanistically explain and unify such enigmatic conditions such as infantile esotropia, latent nystagmus, primary oblique muscle overreaction action, dissociated vertical divergence, infantile nystagmus, and intermittent exotropia in terms of ancestral evolutionary reflexes which become expressed in different ways to generate these disorders. This collection of essays is poised to become a classic reference, providing the necessary neurological framework for contextualizing unique ocular motor disorder and understanding the evolutionary mechanisms responsible for their development in early childhood. Written with focused interest for pediatric ophthalmologists and neuro-ophthalmologists, this reference will also find audience with ophthalmologists, neurologists, evolutionary biologists, and neuroscientists.

Available in PDF, EPUB and Kindle. Book excerpt: For the latest twenty to thirty years, a significant number of AUVs has been created for the solving of wide spectrum of scientific and applied tasks of ocean development and research. For the short time period the AUVs have shown the efficiency at performance of complex search and inspection works and opened a number of new important applications. Initially the information about AUVs had mainly review-advertising character but now more attention is paid to practical achievements, problems and systems technologies. AUVs are losing their prototype status and have become a fully operational, reliable and effective tool and modern multi-purpose AUVs represent the new class of underwater robotic objects with inherent tasks and practical applications, particular features of technology, systems structure and functional properties.
Download or read book Top Catch written by John Eichelsheim and published by Penguin Random House New Zealand Limited. This book was released on 2011-08-26 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Zealand's top 12 fish species and how to catch them. Popular fishing writer John Eichelsheim spills the beans on how and where to catch the best examples of New Zealand's top 12 fish species. John draws on his own forty years of experience fishing around the country to tell personal stories of his own 'top catch' for each species, then provides biological/ geographical information on the fish, the nuts and bolts of tackle and technique, including the peak season, and the current records (biggest fish ever caught etc). He's author has chosen species with appeal for anglers in both main islands and has chosen those that are accessible to the average angler as well as some more 'aspirational' species that need to be caught with specialist gear: snapper, kahawai, blue cod, trout (brown and rainbow), kingfish, trevally, apuku/groper, tuna (yellowfin and albacore), tarakihi, salmon, gurnard and marlin (striped, blue and black). It's both a practical guide and a celebration of our top fish species, full of great yarns and useful information.
Download or read book Ecology of Australian Freshwater Fishes written by Paul Humphries and published by CSIRO PUBLISHING. This book was released on 2013-04-10 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume reviews our past and present understanding of the ecology of Australian freshwater fishes. It compares patterns and processes in Australia with those on other continents, discusses the local relevance of ecological models from the northern hemisphere and considers how best to manage our species and their habitats in the face of current and future threats. In view of these challenges, the need for redress is urgent. The chapters are written by some of our foremost researchers and managers, developing themes that underpin our knowledge of the ecology, conservation and management of fish and fish habitats. For each theme, the authors formulate a synthesis of what is known, consider the need for new perspectives and identify gaps and opportunities for research, monitoring and management. The themes have an Australian context but draw upon ideas and principles developed by fish biologists in other parts of the world. The science of freshwater fish ecology in Australia has grown rapidly from its roots in natural history and taxonomy. This book offers an introduction for students, researchers and managers, one that the authors hope will carry Australian fish biology and resource management to new levels of understanding.
