Available in PDF, EPUB and Kindle. Book excerpt: This manual, a title in the FAO Fishing Manual series, provides and explanation of general calculation principles, design procedures and test methods, to enable fishing gear designers and technologists, teachers and fisherment to solve problems in design, research and fishing operations. It avoids higher mathematics and succeeds in simplifying description of complex design and testing procedures. The knowlede here imparted can help to refine existing gear methods and introduce new ones to the benefit of fisheries in developed and undeveloped countries.

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.
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.

Download or read book Fish Catching Methods of the World written by Otto Gabriel and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the sixteen years since the last edition of Von Brant’s classic work was published, fishing and fisheries have undergone vast changes. Not only has there been great progress in the development of new tools, materials and techniques, but the industry has seen an increasing need to address controversial issues such as declining fish stocks, enormous quantities of bycatch and discard and the impact of towed fishing gear on the environment. Fully revised and updated to reflect such changes, the fourth edition of this widely read and popular book offers: A unique, comprehensive survey of the evolution of fishing methods throughout the world Approximately 750 illustrations showing the extensive range of methods, techniques and equipment used in fishing across the globe Fishing gear classified according to the FAO system Additional chapters: Fishing Effects on Fish Stocks and Environment and Fishery and Gear Research All researchers, fisheries scientists, fisheries students, administrators and libraries in universities and research establishments where fish and fisheries are studied and taught will find this book a valuable addition to their shelves. Commercial and sports fishermen will also find Fish Catching Methods of the World a fascinating and vital reference.

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.
