ISBN: 9789351306702
Category : Technology & Engineering

Pages : 256
Book Description
The net, among the fishing gear occupies the prime position in catching fish commercially for mass production. Among the net, trawl net chase the fish to be caught, as such, has established itself as the most important gear throughout the world oceans. With these objectives, the book in its nineteen chapters, not only, outlined the features of the trawl net, but described the operational characteristics of the net in different operating conditions.. Starting with the principles of the design and construction of the net, the evolution of various trawl fishing gears, tested on trials over time series, from the conventional two seam trawl to four and six seam trawls with overhang, bulged belly, long wing, large mesh, tested for operation at different depths were elaborately described in different chapters of the book. The incorporation of By catch Reduction Devices, a new innovation adopted as conservation measures together with the common by catch species encountered in Indian Seas have also find place in the book. The engineering performance of trawl net in operation towards perfection was elaborately discussed in flume tank test. The reaction and behavior of fish school towards approaching trawl was vividly observed under water and narrated in the book. The possibility of introducing electrical trawl in sea fishing with technical back-up was discussed in details. The construction details and diagrams of different types of trawl presented in the book will be useful to the students, teachers, net-makers and net manufacturers.

Fisheries Technologies for Developing Countries
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309037883
Category : Technology & Engineering
Languages : en
Pages : 177
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.
Modern Fishing Gear Technology
Author: M. Shahul HameedPublisher: Daya Books
ISBN: 9788170352235
Category : Fisheries
Languages : en
Pages : 210
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.
Fishing Vessel Safety

ISBN: 0309043794
Category : Technology & Engineering
Languages : en
Pages : 303
Book Description
In response to a continuing high loss of commercial fishing vessels and crews, the U.S. Congress has mandated development of new safety requirements for the industry. This volume provides a blueprint for an integrated national safety program that responds realistically to industry conditions, with priority on the most cost-effective alternatives. Fishing Vessel Safety addresses the role of the U.S. Coast Guard and the fishing industry and evaluates such safety measures as vessel inspection and registration, and the training and licensing of fishermen. It explores vessel condition, the role of human behavior, the problem of weather prediction, the high cost of insurance, and more.
