Informationen zum Autor PINGGUO HE, PhD, is an Associate Professor in the School for Marine Science and Technology at the University of Massachusetts Dartmouth. Prior to this position, he was a Research Associate Professor of Fisheries at the Institute for the Study of the Earth, Oceans, and Space and an Extension Specialist for Commercial Fisheries at the New Hampshire Sea Grant, the University of New Hampshire. Dr. He specializes in fish behavior during capture processes and conservation engineering principles to reduce impact of fishing to the marine ecosystem. Klappentext 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. Zusammenfassung 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.
