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

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

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

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

At times we take it for granted, it's just an extension of our arm, but how much do you know about the development of your fly rod? Don Phillips gives the reader a perspective of how fly-rod technology has evolved since the earliest Chinese and Egyptian fishermen fed their families more than 2000 years before the birth of Christ. In this book, Don shares: the history, including the very first rods; fly-rod design over the years; the use of cane, metal, fiberglass, and boron and graphite; the properties of these materials; manufacturing processes for these materials; component design; patent activities over the years; casting; taper and cross-sectional geometry; and much, much more. You'll find this very detailed book hard to put down.

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

The fishing technology of the Classical world has so far received little systematic attention, neither from historians nor from archaeologists. In this volume, the reader will find a series of studies offering a wide range of approaches to the topic of ancient fishing technology, based on detailed studies of the available literary, archaeological, pictorial and icthyological evidence as well as on diachronic comparisons with fishing techniques of the Early Medieval and Modern periods. The articles included in the present volume are based on the authors' presentations at an international, interdisciplinary workshop in Cadiz, covering the history of fishing from Pre-history to the present day, with a special emphasis on the Roman period.
