Download or read book Mortality of Fish Escaping Trawl Gears written by Petri Suuronen and published by Food & Agriculture Org.. This book was released on 2005 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress has been made in reducing bycatch and discards through improving the selectivity of fishing gear. This publication examines the key factors affecting the stress, injury and mortality of fish arising from fishing processes, particularly when fish escape from trawl equipment. It seeks to identify improved methodological approaches and practices, and to consider the design of fishing gears and operations that reduce or eliminate such deaths, and to assess the problems associated with estimating the impact of unaccounted fish mortality.
Download or read book Innovations in Fishing Technology Aimed at Achieving Sustainable Fishing written by Alessandro Lucchetti and published by Frontiers Media SA. This book was released on 2023-11-20 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last fifty years, human exploitation of marine resources has become more efficient as the understanding of the habits and behaviour of the various species available in the sea gradually increased. Thus, technologies have developed naturally over time and fishing gears and practices have become more sophisticated. These technical advances in fishing gear have generally led to more efficient economic fishing operations and better access to resources. However, fishing implies the harvesting of marine organisms directly from their natural environment, therefore general awareness of environmental problems due to the exploitation of fishery resources has also increased. In particular, the poor selectivity of some gears is responsible for the capture of juveniles, immature and undersized specimens of many species, with negative consequences on the state of stocks. In addition, bycatch in marine fisheries is a major source of human-caused mortality of marine megafauna, often leading to the capture of vulnerable species. Finally, many bottom-towed gears are responsible for high impacts on bottom communities and habitats, with cascading consequences on the entire marine ecosystem. All these impacts can lead to changes in the structure, function and integrity of ecosystems, including effects on the food webs and multispecies predator-prey relationships.

Download or read book Flatfishes written by Robin N. Gibson and published by John Wiley & Sons. This book was released on 2015-01-20 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fascinating and instantly recognizable, flatfishes are unique in their asymmetric postlarval body form. With over 800 extant species recognized and a distribution stretching around the globe, these fishes are of considerable research interest and provide a major contribution to commercial and recreational fisheries worldwide. This second edition of Flatfishes: Biology and Exploitation has been completely revised, updated and enlarged to respond to the ever-growing body of research. It provides: • Overviews of systematics, distribution, life history strategies, reproduction, recruitment, ecology and behaviour • Descriptions of the major fisheries and their management • An assessment of the synergies between ecological and aquaculture research of flatfishes. Carefully compiled and edited by four internationally-known scientists and with chapters written by many world leaders in the field, this excellent new edition of a very popular and successful book is essential reading for fish biologists, fisheries scientists, marine biologists, aquaculture personnel, ecologists, environmental scientists, and government workers in fisheries and fish and wildlife departments. Flatfishes: Biology and Exploitation, Second Edition, should be found in all libraries of research establishments and universities where life sciences, fish biology, fisheries, aquaculture, marine sciences, oceanography, ecology and environmental sciences are studied and taught. Reviews of the First Edition • A solid, up-to-date book that advanced students and research scientists with interests in fish biology will find interesting and useful. Aquaculture International • A data-rich book that outlines much of what you might ever want to know about flatfishes. Fish & Fisheries • Well presented with clear illustrations and a valuable source of information for those with a general interest in fish ecology or for the more specialist reader. You should make sure that your library has a copy. J Fish Biology • An excellent and very practical overview of the whole, global flatfish scene. Anyone interested in flatfish at whichever stage of the economic food chain should invest in a copy immediately. Ausmarine • Because of the high quality of each chapter, written by international experts, it is a valuable reference. Reviews in Fish Biology and Fisheries
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

This book was released on 2008-04-29 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual defines methods for estimating selectivity of gillnet and longline gears, with particular reference to the use of these gears in abundance surveys. The manual illustrates how gear design, the basic concepts of size selection and fish morphometric data can be used to model selectivity. Statistical estimation methods are described in detail, and examples given of their application in spreadsheets. The efficient use of these gears in abundance and research surveys is also discussed. Although the manual concentrates on gillnets and longlines, the methods given are general enough to be relevant to any research involving gear selectivity
