    Fuel and financial savings for operators of small fishing vessels 1999
    Also available in:

    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.

    Reducing The Fuel Costs Of Small Fishing Boats - BOBP/WP/27 1986

    The first part of this paper describes the principles of power requirements for small fishing boats and details ways of saving fuel which can be applied both with existing boats and new boats. It also illustrates by example how to estimate the savings from measures to conserve fuel. The second part of the paper describes fuel consumption trials carried out in Sri Lanka. During the trials the two most common Sri Lankan boats - the 18 footer and 28 footer — were used with different engines, propellers and hull conditions, and actual fuel consumption was recorded. The fuel consumption performance of two BOBP craft - SRL-14 and SAL-15 - was tested in comparison with that of the standard 28-footer of Sri Lanka; the fuel performance of another BOBP craft, SRL-17, was compared with that of Sri Lanka’s standard 18-footer. The results of the trials confirmed the validity of the principles and fuel-saving recommendations described in the first part. The trials were conducted in 1982 at the request of the Ministry of Fisheries, Sri Lanka. A report was submitted to the Ministry soon after the trials.

    Building small wooden boats in Myanmar - 12 ft and 18 ft Multi-purpose boats

    This step-by-step manual contains information on the construction of small multi-purpose boats typical of those found in the Ayeyarwaddy Delta in Myanmar. Its purpose is to give organizations access to detailed information on boatbuilding, which will allow the production of small boats appropriate to the Delta. The manual is also intended to assist organizations in their understanding of the boatbuilding process and to provide guidelines on good practice. It should assist in the review o f contracts and quality control in boatbuilding. The manual provides information on two boat designs: 12 ft and 18 ft boats. It also gives the scantlings and material requirements as well as the guidelines for selecting and using timber for the boat construction. The largest part of the manual describes how to build the boats step-by-step. Finally, the manual contains boatbuilding guidelines for wooden boats of less than 7 m in length and operating at speeds of less than 12 knots.
