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.

Download or read book Reef Fisheries written by Polunin Nicholas V.C. and published by Springer. This book was released on 2014-10-09 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reef ecosystems extend throughout the tropics. Exploited by small-scale fishers, reefs supply food for millions of people, but, worldwide, there are growing worries about the productivity and current state of these ecosystems. Reef fish stocks display many features of fisheries elsewhere. However, habitat spatial complexity, biological diversity within and among species, ecosystem intricacy and variable means of exploitation make it hard to predict sustainable modes and levels of fishing.

Download or read book Wildlife Demography written by John R. Skalski and published by Elsevier. This book was released on 2010-07-20 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildlife Demography compiles the multitude of available estimation techniques based on sex and age data, and presents these varying techniques in one organized, unified volume. Designed to guide researchers to the most appropriate estimator based upon their particular data set and the desired level of study precision, this book provides quantitative consideration, statistical models, estimator variance, assumptions and examples of use. The authors focus on estimation techniques using sex and age ratios because this data is relatively easy to collect and commonly used by wildlife management. Applicable to a wide array of wildlife species, including game and non-game birds and mammals Features more than 100 annotated examples illustrating application of statistical methods Includes more than 640 references of the analysis of nontagging data and the factors that may influence interpretation Derives historical and ad hoc demographic methods in a modern statistical framework

Download or read book Modern Fishing Gear Technology written by M. Shahul Hameed and published by Daya Books. This book was released on 2000 with total page 210 pages. 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. 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.
Download or read book Fish Catching Methods of the World written by Andres von Brandt and published by Fishing News Books Limited. This book was released on 1984 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Methodology Manual Measurement of Fishing Gear Selectivity written by Dickson, W and published by Fisheries and Oceans. This book was released on 1995-01-01 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing selectivity can be defined as the ability to target and capture fish by species, size, or sex (or a combination of these) during harvesting operations, allowing all incidental by-catch to be released unharmed. This manual outlines the steps and processes necessary to monitor selectivity demonstrations, collect data on selectivity, and validate scientific research on selectivity under normal fishing operations. Some mathematical and statistical examples are shown to clarify the methodologies and to facilitate understanding and application. The manual is intended to provide assistance to technicians and senior fishing crew in the planning, execution, and reporting of size and species trials and demonstrations with mobile and fixed gears. Sections of the manual cover measurement of selectivity, experiment design, experimental methods, data analysis, and the reporting of results. Case studies of experiments using both fixed and mobile gear are included.
