Fishing continues to be the most energy-intensive food production method in the world today, and it depends almost completely upon oil fuel-based internal combustion engines. There are as yet no signs of any other energy source that could substitute the internal combustion engine in either the medium or short term. The industry continues to be exposed to global fuel prices and it cannot be assumed that these will remain stable indefinitely. Small-scale fisheries account for nearly half of the world's fish production and, although they are generally more labour-intensive than larger industrial fisheries, they are increasingly affected by energy costs. In developing countries, in spite of the energy conservation initiatives of the 1980s (subsequent to the dramatic rise in the cost of fossil fuels), mechanization continues to increase. Fuel costs have ever more influence not only on consumer prices but also on fishermen's and boat owners' net incomes. When levels of employment and cost-sharing systems are considered, it becomes even more important from a social perspective to improve and maintain energy efficiency within small-scale fisheries. This guide presents information on the key technical areas that affect energy efficiency, but only part of the information presented herein will be applicable to any particular fishing situation. The guide is not a result of new original fieldwork but draws on much of the research and experience of the past two decades, updated where possible to include new technical developments. The guide is divided into two major sections: the first relates to changes in operational techniques rather than changes in technology; the second presents information of relevance to vessel operators who are either considering the construction of a new vessel or overhauling and re-equipping an existing vessel.

This book describes the feasibility and status of the use of alternative fuels in marine engineering, as well as the application of liquefied natural gas, biodiesel and their blends as marine fuels, and the combustion of synthetic coal-based fuels. Each chapter in the book ends with a summary, which gives the reader a quick and clear understanding of the main contents of the chapter. The book gives a lot of advice on the selection of equipment and parameters, fuel reserves and preparation for scholars related to alternative fuels in ships, and points them in the way. It contains lots of illustrations and tables and explains it in the form of chart comparison. The authors have developed mathematical models and methods for calculating the parameters of fuel systems for biodiesel fuels and liquefied natural gas. Recommendations for choosing the rational parameters of these systems are given, as are schematic solutions of the fuel systems, recommendations for selecting equipment, storing, and preparing the fuels. Application of the materials described in the book provides the SPP designers with a reliable tool for choosing rational characteristics of the fuel systems operating on alternative fuels and improving the efficiency of their application on ships.

"The recent sharp increase in the price of fuel has had a major impact on the economics of operating fishing vessels. Fishing boat owners and operators struggle to meet this challenge and ask what measures can be taken to reduce the heavy burden of increased fuel cost. Litres of fuel required per tonne of fish landed varies widely depending on the fish specia and fishing method used. Fuel saving methods have to be tailored to each fishing method and fishery. This manual aims to provide practical advice to fishing boat owners and crews, boatbuilders and boat designers and fisheries administrators on ways to reduce fuel costs. It focuses on small fishing boats measuring up to 16 m (50 ft) in length and operating at speeds of less than 10 knots. This covers the majority of the world's fishing boats. It also serves as a guide for those involved with fuel savings for small vessels used in support of aquaculture activities. The manual provides information to boat designers and boat builders on hull shape for low resistance and the selection of efficient propellers. The first chapters of this manual deal with fuel saving measures that can be taken on existing boats without incurring major investment costs. The most effective measures include reducing boat service speed, keeping the hull and propeller free from underwater fouling and maintaining the boat engine. It also suggests that changing fishing methods can save fuel. The final chapters of this manual provide information regarding the fuel savings that are possible by changing from a 2-stroke outboard engine to a diesel engine, installing a diesel engine, and using sail. Selecting economic engine power on the basis of the waterline length and the weight of the boat is discussed. Advice is given on the choice of gear reduction ratio and of propeller related to service speed, service power and propeller rpm. Data are provided to assist with the design of a new fuel-efficient boat and the selection of an optimum propeller. The information contained in this manual is accompanied by many illustrations to make the main points more easily understood. Detailed background information is provided in the appendices. The appendices also contain blank tables that may be used to calculate potential fuel savings, cost of engine operation, the weight of a boat and the diameter and pitch of a propeller."--Publisher's description.

This techno-economic performance review of selected fishing fleets in Asia presents the findings of six country level studies of fishing fleets in Bangladesh, China, India, Indonesia, Japan and the Republic of Korea. The review includes financial and economic information of 27 major fishing fleet segments, including trawlers, gillnetters, long liners, jiggers, purse seiners, as well as pole and line fishing vessels. An analysis of the costs and earnings data of these important fishing fleet segments in Asia was carried out using national statistics of 2017 for the Japanese and the Korean fleet segments and 2018-19 survey data for the other countries. Eighty-nine percent of the 27 fishing fleet segments reported positive net cash flows. Seventy percent of the fishing fleets realized net profit margins of more than 10 percent. Eighty-one percent of the fishing fleets reported positive results in terms of their capital productivity, as theirs returns on fixed tangible assets (ROFTAs) were positive.The review shows that investments in fishing vessels and fishing operations of these major Asian fishing fleets are generally profitable. Marine capture fishing is a financially viable economic activity in all six major fishing nations included in the review. It generates enough income to cover depreciation costs, interest and loan repayments, and provides sufficient financial resources for reinvestment. Nearly 60 percent of the fishing fleets generated returns on investment (ROIs) of 15 percent and higher, which signals an attractive sector for investments. The total gross value added (GVA) of the 27 fishing fleets to the Asian regional economy was substantial and estimated at around USD 66 billion. The review also reveals a need for adequate management measures, including fleet capacity management plans, to improve the status of fish stock in the region and maintain a healthy and profitable fishing sector.

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.
