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 A Device for Stamina Measurement of Fingerling Salmonids Book in PDF, ePub and Kindle
A stamina tunnel was developed to measure differences in physical performance of salmonid fingerlings. By subjecting fish samples to controlled patterns of water velocity, it has proved possible to demonstrate differences in fish stamina imparted by disease, nutrition, and environment.

Download Behavior of Marine Fishes Book in PDF, ePub and Kindle
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 The Evolutionary Basis of Strabismus and Nystagmus in Children Book in PDF, ePub and Kindle
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.
