Download or read book Longlining written by Åsmund Bjordal and published by Wiley-Blackwell. This book was released on 1996-09-20 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longlining is becoming increasingly more important as a method of fishing commercially for certain prime species of fish- particulary in the face of declining stocks. Longlining is much more selective that any other form of fishing and is thus more environmentally acceptable. Furthermore, longlining allows for the targeting of particular prime species and fish caught by this method are less damaged and thus hold a higher value. Despite the many major benefits of longlining, there are, as yet few books which address the technical and economic aspects of this method of commercial fishing. Written by an expert, this new book describes the principles and development of longlining fishing and explains the action of chemical sensing in fish and their behaviour towards baited hooks. Details of gear construction, the operation cycle for longlines, longline vessels and the different principles of mechanised baiting and on-board gear handling are provided and typical examples are given. The target species, gear parameters and catching efficiency, and the selective properties of longline gear are fully discussed whilst a concluding chapter compares longlining with other fishing methods.

Download or read book Dolphins and the Tuna Industry written by National Research Council and published by National Academies Press. This book was released on 1992-02-01 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents key conclusions about the controversial killing of thousands of dolphins each year during tuna fishing in the eastern tropical Pacific. Dolphins drown in nets that are set to catch yellowfin tuna, which tend to swim beneath dolphin herds. After 20 years of intense debate among environmentalists, the tuna industry, and policymakers, this fatal by-product of tuna fishing remains a high-profile public issue. Dolphins and the Tuna Industry provides a neutral examination of the scientific and technical questions at the core of the problem. Recommendations for solutions are offered in two areas: developing new techniques that promise to reduce dolphin mortality with the existing purse-seine method of tuna fishing, and developing entirely new methods of finding tuna that are not swimming with dolphins. Dolphins and the Tuna Industry provides a comprehensive, highly readable overview of the dolphin-tuna controversy, useful to experts and newcomers to the issue. It explores the processes of tuna fishing and dolphin mortality, the status of the tuna industry, and the significant progress made in reducing dolphin mortality through modifications in fishing practice. The volume includes: An overview of U.S. laws and policies relating to tuna and dolphins. An illustrated look at how tuna fishing crews use their equipment, focusing on the purse seine, which is the method most economical to the industry but most deadly to the dolphins. An overview of what is known about tuna and dolphin populations and the remarkable bond between them. A step-by-step description of the fishing process and efforts to let dolphins escape from the nets. An analysis of possible approaches to reducing dolphin kill, including more stringent regulatory approaches and incentives for the tuna industry. This book will be indispensible to environmental and animal protection groups, tuna fishing crews and processors, companies that market tuna products, policymakers, regulators, and concerned individuals.

Download or read book Historical Trends of Tuna Catches in the World written by Makoto Miyake and published by Food & Agriculture Org.. This book was released on 2004 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total world catch of the major commercial tuna species (albacore, bigeye, bluefin, skipjack and yellowfin) has increased during the last 50 years (from 0.4 to 3.9 million tonnes), but the pattern of increase has varied among species, oceans and fishing gears. The Pacific Ocean has been the predominant region in the world catch, with catches from the Indian Ocean having exceeded those from the Atlantic Ocean in recent years. This publication examines historical trends in the catches of these tuna species and considers the causes of the variations.

Download or read book Fisheries Technologies for Developing Countries written by National Research Council and published by National Academies Press. This book was released on 1988-02-01 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: In developing countries, traditional fishermen are important food contributors, yet technological information and development assistance to third-world nations often focuses on agriculture and industrial fishing, without addressing the needs of independent, small-scale fishermen. This book explores technological considerations of small-scale, primitive fishing technologies, and describes innovative, relatively inexpensive methods and tools that have already been successfully applied in developing countries. It offers practical information about all aspects of small-scale fishing, including boat design and construction, fishing methods and gear, artificial reef construction and fish aggregating devices, techniques for coastal mariculture, and simple methods for processing and preserving fish once they are caught. Fisheries Technologies for Developing Countries is illustrated throughout with photographs of the devices and construction methods described in the text.

This book was released on 2021-07-02 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document elaborates the revised International Standard Statistical Classification of Fishing Gear (ISSCFG), as endorsed and adopted for implementation by the FAO Coordinating Working Party on Fishery Statistics (CWP) at its Twenty-fifth Session in February 2016 in Rome, Italy. The classification applies to commercial, subsistence and recreational fisheries in marine and freshwater fisheries. The document provides definitions and illustrations of the configuration and mode of operation of typical fishing gears. The primary purpose is to assist FAO Members, regional fishery bodies, as well as those working on fishery statistics and management, to correctly attribute and report fisheries catches made by different gear types. The document also contributes to the prevention, deterrence and elimination of illegal, unreported and unregulated (IUU) fishing by providing monitoring, control and surveillance personnel with information to identify the type of fishing gear with regard to licence and authorization to carry out fishing operations. Finally, the document also provides context and references for some contemporary conservation issues related to major fishing gear types; it can therefore be used as a reference text for students and researchers in fisheries and marine conservation.

Download or read book Fisherman s Workbook written by J. Prado and published by Wiley. This book was released on 1991-01-15 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unusual pocketbook, designed for fishermen, netmakers, boatbuilders and other professionals, provides easy reference on land or sea, to a wealth of useful information. It is presented in five parts. The first helps with the choice and use of materials; the second with the choice of fishing gear; the next outline the characteristics of echo sounders and deck machinery for handling fishing gear. Then comes information on the most effective use of fishing vessels, and guidelines for calculating costs and benefits of fishing operations. Finally basic formulae and tables are given and a section on ordering equipment. Fishing technologies are not dependent on exact science, for individual experience, knowledge and skill are of great importance. This workbook therefore contains sets of guidelines drawn from the wide experience of master fishermen, to be used in combination with the individual's own experiences, knowledge and expertise.

Available in PDF, EPUB and Kindle. Book excerpt: A diverse range of fishing gears and methods have been evolved to capture a wide range of species constituting the fisheries in different parts of the world. Significant developments have taken place in the fishing gear materials, design and fabrication and degree of sophistication in the operation and handling of fishing gears, in the last three decades. Advances in vessel technology, precision electronic navigation systems, high definition fish finders and sonar, gear monitoring systems and computerised control systems have increased the precision and efficiency of fishing. These developments while increasing the fish production have also brought to focus emerging issues such as the need for long term sustainability of fishery resources, fishery enhancement, protection of biodiversity, environmental safety and energy conservation in fish harvesting, which are being addressed in different parts of the fishery world with varying degrees of success. This publication brings together latest information in the field of commercial fishing technology and provides an overview of the important fishing gears, their design, fabrication and operation with focus on recent advances in responsible focuses on the requirements of the graduate and post graduate studies of fisheries science and fishing gear technology.

Download or read book Legal aspects of abandoned lost or otherwise discarded fishing gear written by Hodgson, S. and published by Food & Agriculture Org.. This book was released on 2022-01-05 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing quantity of plastic waste in the marine environment including abandoned, lost or otherwise discarded fishing gear (ALDFG) is a global problem. A particular feature of ALDFG is the potential of some gears to carry on fishing for many months or even years. The study examines legal responses to ALDFG in the context of marine fisheries. After discussing the nature of the problem of ALDFG and some of the reasons why fishing gear is abandoned, lost, or otherwise discarded, the study examines the response of the international community to ALDFG. A key finding is that ALDFG is at the same time, a fishing issue, a navigation problem (of vessel source pollution) and an environmental problem with the resulting involvement of FAO, IMO and UNEP as well as the UN General Assembly. After examining potential legal approaches to the problem, the study then describes the basic legal and institutional arrangements in four case study jurisdictions that have adopted legal measures to address ALDFG, namely Australia, the European Union and its Member States, Norway and the USA finding once again the tripartite responsibility of fisheries, navigation and environment ministries/agencies. The inter-sectoral nature of ALDFG suggests the need for a collaborative and coordinated approach. While not all of the case study jurisdictions make use of all ten of the individual legal measures identified, the case studies also clearly show that ALDFG is a problem that is susceptible to a legal response at the national or regional level including through the use of extended producer responsibility schemes, various reporting requirements and gear standards. Legal tools to address the problem of ALDFG clearly exist. The extent to which some, or all, of them are necessary or appropriate in a given context at national, regional or global level is not ultimately a legal question but a political one.
