Book excerpt: BYCATCH The main impact of fisheries on biodiversity, beyond simple removal of the target species, is generally considered to be bycatch, defined by the Food and Agricultural Organization of the United Nations (Appendix II) as "the part of a catch taken incidentally in addition to the target species." Generally, bycatch also includes individuals of the target species that are outside the permitted [...] Indirect impacts include changes in the abundance of predators, prey, and competitors of the target species resulting from reduced abundances of the target species and/or the provision of food in the form of discarded bycatch. [...] The action of the ropes on the ocean bottom stirs up a mud cloud and herds fish into the path of the net. [...] The trap is kept upright in the water by floats along the top of the walls and lead weights at the bottom. [...] To reduce the cost of the more effective but also more expensive Japanese trap, a modified Newfoundland cod trap was developed, and combines aspects of the Japanese and Newfoundland traps by simply adding the half-funnel doorway from the front room of the Japanese trap to the traditional trap (Armour et al., 1991).

Book Synopsis Marine Conservation by : G. Carleton Ray
Download or read book Marine Conservation written by G. Carleton Ray and published by John Wiley & Sons. This book was released on 2013-10-11 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a guide for marine conservation practice, Marine Conservation takes a whole-systems approach, covering major advances in marine ecosystem understanding. Its premise is that conservation must be informed by the natural histories of organisms together with the hierarchy of scale-related linkages and ecosystem processes. The authors introduce a broad range of overlapping issues and the conservation mechanisms that have been devised to achieve marine conservation goals. The book provides students and conservation practitioners with a framework for thoughtful, critical thinking in order to incite innovation in the 21st century. "Marine Conservation presents a scholarly but eminently readable case for the necessity of a systems approach to conserving the oceans, combining superb introductions to the science, law and policy frameworks with carefully chosen case studies. This superb volume is a must for anyone interested in marine conservation, from students and practitioners to lay readers and policy-makers." —Simon Levin, George M. Moffett Professor of Biology, Department of Ecology & Evolutionary Biology, Princeton University

Download or read book Step-wise guide for the implementation of international legal and policy instruments related to deep-sea fisheries and biodiversity conservation in the areas beyond national jurisdiction written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-10-14 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This step-wise guide aims to assist with the implementation of relevant international instruments pertaining to deep-sea fisheries and biodiversity conservation in areas beyond national jurisdiction, especially the high seas, into national policy and law. This guide focuses on the incorporation and transposition of international rules, standards, and recommended practices and procedures into national policy and law. It addresses the key measures for making international obligations effective at the national level and suggests possible options for integrating those measures into the national legal framework. Legislative examples are also provided to illustrate how certain provisions have been incorporated into primary or secondary legislation. The guide first addresses the establishment of a national policy, followed by a description and analysis of essential legislative provisions regarding deep-sea fisheries and the conservation of marine biological diversity in areas beyond national jurisdiction. This guide is thus relevant to policy-makers, parliamentary draftpersons, and parliamentarians.

Book Synopsis Sustaining Marine Fisheries by : National Research Council
Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
Book Synopsis Effects of Trawling and Dredging on Seafloor Habitat by : National Research Council
Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
Book Synopsis Overview of mitigation measures to reduce the incidental catch of vulnerable species in fisheries by : Sacchi, J.
Download or read book Overview of mitigation measures to reduce the incidental catch of vulnerable species in fisheries written by Sacchi, J. and published by Food & Agriculture Org.. This book was released on 2021-06-23 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potentially harmful contact between fisheries and marine vulnerable species represents a global conservation issue and efforts to mitigate the negative repercussions of these interactions belong in strategies for ensuring the sustainability of fisheries. This literature review offers a survey of mitigation measures and techniques that have been developed and tested around the world, aiming to address both the incidental catch of highly mobile species – specifically, cetaceans, seabirds, sharks and rays, and sea turtles – and depredation caused by dolphins. Based on research detailed in over 300 documents, including peer-reviewed publications, reports from international organizations and papers available on the internet, most of the mitigation techniques illustrated are still under development, with only a few already adopted through legislation. The selected mitigation measures are grouped by main types of fishing gear – gillnets and trammel nets, longlines and lines, trawls, purse seines, traps and pots – and further subdivided according to which of the four main groups of vulnerable species – cetaceans, seabirds, sharks and rays, or sea turtles – they are designed to protect. Preventive and curative approaches covering both technical measures (gear modifications, strategies, as well as acoustic, visual, magnetic and chemosensory deterrents) and management measures are described.

Download or read book The State of World Fisheries and Aquaculture 2018 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-07-10 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2018 edition of The State of World Fisheries and Aquaculture emphasizes the sector’s role in achieving the 2030 Agenda for Sustainable Development and the Sustainable Development Goals, and measurement of progress towards these goals. It notes the particular contributions of inland and small-scale fisheries, and highlights the importance of rights-based governance for equitable and inclusive development. As in past editions, the publication begins with a global analysis of trends in fisheries and aquaculture production, stocks, processing and use, trade and consumption, based on the latest official statistics, along with a review of the status of the world’s fishing fleets and human engagement and governance in the sector. Topics explored in Parts 2 to 4 include aquatic biodiversity; the ecosystem approach to fisheries and to aquaculture; climate change impacts and responses; the sector’s contribution to food security and human nutrition; and issues related to international trade, consumer protection and sustainable value chains. Global developments in combating illegal, unreported and unregulated fishing, selected ocean pollution concerns and FAO’s efforts to improve capture fishery data are also discussed. The issue concludes with the outlook for the sector, including projections to 2030. As always, The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to- date information to a wide audience, including policy-makers, managers, scientists, stakeholders and indeed all those interested in the fisheries and aquaculture sector.
Book Synopsis Marine Animal Forests by : Sergio Rossi
Download or read book Marine Animal Forests written by Sergio Rossi and published by Springer. This book was released on 2017-08-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades there has been an increasing evidence of drastic changes in marine ecosystems due to human-induced impacts, especially on benthic ecosystems. The so called “animal forests” are currently showing a dramatic loss of biomass and biodiversity all over the world. These communities are dominated by sessile suspension feeder organisms (such as sponges, corals, gorgonians, bivalves, etc.) that generate three-dimensional structures, similar to the trees in the terrestrial forest. The animal forest provide several ecosystem services such as food, protection and nursery to the associated fauna, playing an important role in the local hydrodynamic and biogeochemical cycles near the sea floor and acting also as carbon sinks. The present book focus its attention on these three dimensional animal structures including, for the first time, all the different types of animal forests of the world in a single volume.
Book Synopsis Fish Catching Methods of the World by : Andres von Brandt
Download or read book Fish Catching Methods of the World written by Andres von Brandt and published by Fishing News Books Limited. This book was released on 1984 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book grew out of Professor Von Brandt′s lifetime devotion to the study of fishing gears and catching methods from prehistoric times to the present. In it he shows how the main components of early methods – netting, lines, hooks, floats and sinkers – are still in common use even though their efficiency has been improved. His extensive travels have enabled him to include examples from many eras and many different parts of the world and his descriptions are enhanced by hundreds of illustrations. He describes gears in logical sequence from the most primitive gathering methods to the possible use of fully automated harvesting machines totally operated by computers. Also, he has developed a rational classification system for the multitude of fish devices and techniques. Although this has been done in a most scholarly way, the resultant text is alive with interesting anecdotes. This meticulously compiled edition will be invaluable to eveyone concerned with commercial fisheries as well as a delight to sport fishermen and all with an interest in fish or its capture.
