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

The focus of this report is technologies for fish passage around hydropower generation facilities and protection against entrainment and turbine mortality. Emphasis is given to Federal Energy Regulatory Commission (FERC)-licensed hydropower projects where fish protection is a subject of controversy and congressional interest due to the Federal Power Act (FPA) and the Electric Consumers Protection Act (ECPA). Thus institutional issues related to FERC-relicensing are also discussed. (Major points of controversy are high-lighted in box 1.1).

Rivers have been intensively degraded due to increasing anthropogenic impacts from a growing population in a continuously developing world. Accordingly, most rivers suffer from pressures as a result of increasing dam and weir construction, habitat degradation, flow regulation, water pollution/abstraction, and the spread of invasive species. Science-based knowledge regarding solutions to counteract the effects of river degradation, and melding principles of aquatic ecology and engineering hydraulics, is thus urgently needed to guide present and future river restoration actions. This Special Issue gathers a coherent set of studies from different geographic contexts, on fundamental and applied research regarding the integration of ecohydraulics in river restoration, ranging from field studies to laboratory experiments that can be applied to real-world challenges. It contains 13 original papers covering ecohydraulic issues such as river restoration technologies, sustainable hydropower, fish passage designs and operational criteria, and habitat modeling. All papers were reviewed by international experts in ecology, hydraulics, aquatic biology, engineering, geomorphology, and hydrology. The papers herein well represent the wide applicability of ecohydraulics in river restoration and serve as a basis to improve current knowledge and management and to reduce arguments between different interests and opinions.

This new definitive volume on fish auditory systems will interest investigators in both basic research of fish bioacoustics as well as investigators in applied aspects of fisheries and resource management. Topics cover structure, physiology, localization, and acoustic behavior as well as more applied topics such as using sound to detect and locate fish.

The use of water for industrial purposes is of foremost importance. It is used as a coolant and industrial activities dealing with power generation, steel and iron, paper and pulp and oil require very large amounts of water. The industry, therefore, resorts to large scale abstraction of water from natural water bodies. This water is often treated with chemicals to combat operational problems like biofouling and corrosion. Such withdrawal and subsequent discharge of large amounts of water have the potential to impart significant impact on the recipient water body. The organisms drawn along with the cooling water, as well as those residing at the discharge zone, are subjected to a combination of mechanical, thermal and chemical stress on a continuous basis.

Clinical Guide to Fish Medicine Designed as a practical resource, Clinical Guide to Fish Medicine provides an evidence-based approach to the veterinary care of fish. This guide—written and edited by experts in the field—contains essential information on husbandry, diagnostics, and case management of bony and cartilaginous fish. This important resource: Provides clinically relevant information on topics such as anatomy, water quality, life-support systems, nutrition, behavioral training, clinical examination, clinical pathology, diagnostic imaging, necropsy techniques, anesthesia and analgesia, surgery, medical treatment, and transport Describes common presenting problems of fish, including possible differentials and practical approaches Reviews key information on non-infectious and infectious diseases of fish in a concise format that is easily accessible in a clinical setting Written for veterinarians, biologists, technicians, specialists, and students, Clinical Guide to Fish Medicine offers a comprehensive review of veterinary medicine of fish.

The freshwater eels, the Anguillids, have increasingly become the focus of attention for fisheries managers, scientists, researchers, policy makers, conservation bodies and other stakeholders. These species can be seen as a bellwether for issues affecting aquatic ecosystems – their steep decline and the management initiatives to try and reverse this trend, touch on subjects as diverse as disconnected waterways, loss of habitat, novel parasites, pollution, over-fishing and climate change. There are some 16 species of the Anguilla genus and all exhibit similar lifestyles, growing in waters often far-removed from their marine spawning grounds. These enigmatic, contradictory and confounding species share similar challenges and pressures wherever they are found. This book was generated from the 1st UK International Eel Science Symposium which was held at the Zoological Society of London (ZSL) in June 2017. Hosted by the Institute of Fisheries Management (IFM), the ZSL, and the Environment Agency (EA), the Symposium was heralded as a success, with over 180 delegates in attendance. Many of the world’s top eel specialists attended or gave presentations across a diverse range of subjects. This was one of the Symposium’s, and now the book’s great strengths – its diversity of subjects and authors. Many countries are represented within the book, from across Europe and as far afield as New Zealand, South Africa, Vanuatu, French Polynesia, Japan, Canada and the USA. The EA and IFM have collaborated to produce this landmark book which includes a mix of cultural, scientific and management information which will be invaluable to anyone with a professional or personal interest in these mysterious fish, including ichthyologists, fisheries scientists and managers, aquaculture personnel, environmental biologists and ecologists, marine and freshwater biologists, vertebrate zoologists, animal behaviourists and students studying in all these areas. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves. 5m Books
