Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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. Contents Chapter 1: Introduction; Chapter 2: Fishing Gear Materials; Chapter 3: Classification of Fishing Gears; Chapter 4: Basic Principles of Fishing Gear Design and Construction; Chapter 5: Design and Operation of Major Fishing Gears, Trawls, Purse seines, Lines, Gill nets & trammel nets, Traps; Chapter 6: Fish Detection Methods; Chapter 7: Selectivity of Fishing Gears; Chapter 8: Energy Conservation in Fishing; Chapter 9: Responsible Fishing.

Book Description
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 Description
Trawls of various designs and sizes were compared to evaluate their use for monitoring and harvesting fish populations in Lake Oahe. Catches of a 20.7-m semiballoon trawl, selected to monitor changes in the fish populations from 1965 to 1970, showed a downward trend in the abundance of all species, except walleye; the decline was largest in the lower area of the reservoir with a slight increase in the upper area. Of two trawl designs tested, semiballoon trawls captured more fish per hour than high-rise trawls, and a 15.9-m semiballoon trawl with a 3.8-cm mesh cod end captured fish at the highest and most consistent rate. The size and species composition of the fish caught in small-mesh trawls differed from thos caught in trap nets. Trawl cataches were too small to recommend or warrant their use as a commercial fishing gear, but the use of both small mess trawls and trap nets should improve accuracy in monitoring fish populations in this reservoir.

Book Description
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.
