Download or read book Fish Swimming in Turbulent Waters written by Hubert Chanson and published by CRC Press. This book was released on 2020-09-13 with total page 203 pages. 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 The Norwegian Coastal Current written by and published by Fagbokforlaget. This book was released on 2007 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Norwegian coastal current originates primarily from the freshwater outflow from the Baltic and the freshwater runoff from Norway. It flows northwards along the coast of Norway as a low-salinity current. This coastal region is the spawning ground for a number of important oceanic fish stocks, and the physical environment has an impact on the recruitment, growth, and geographical distribution of these stocks. In the late 1920s and early 1930s, the Institute of Marine Research in Norway established a coastal oceanographic observation system. This continued to evolve, and its core elements are still in operation. Drawing on the results generated by this observation system, as well as by other coastal studies, this book reviews the current understanding of the physical/chemical conditions in the Norwegian coastal current in such a way as to make the material more easily accessible to non-specialists. A series of chapters introduces readers to the geography, currents, water masses, and the temporal and spatial variability of the Norwegian coastal current. Interannual fluctuations in physical conditions are most likely to be the prime cause of ecosystem variability. The editor hopes that this book will act as a point of departure for a future summary of the ecology of Norwegian coastal waters.
