Traditional fishermen in developing countries catch around 20 million t of fish every year: about a quarter of the world's total catch. This is landed by an estimated 15 million full and part-time fishermen and processed and marketed by a further 15 million people. Assuming an average family size of six, then some 200 million people are directly dependent on small-scale fisheries. Many more people depend on fishing as their principal source of protein and, in Africa, over 80% of the available fish is caught by artisanal fishermen Fisheries Technology for Developing Countries is a book based on the report of the U S Board on Science and Technologyfor International Development (BOSTID) and addresses itself directly to the needs of small-scale fisheries in developing countries. Contributions to the report have been drawn from all around the world giving a wide-ranging and informed assessment of the current situation and possibilities for the future However, the book is entirely practical in its outlook, acknowledging that 'Artisanal fishermen will only embrace and continue to use new technologies that satisfy their own economic interests. Any increased capital, or operating or maintenance costs must be balanced by an increased catch which translates into increased profit. Careful cost-benefit analyses, feasibility studies and pilot projects must be undertaken to ensure that this is indeed the case' In this context the authors point out that the average artisanal catch may be low but in terms of fish catch per ton of fuel it is much higher than in the industrial sector. This reflects the overall view of the book that fish catches and thus the quality of life of many coastal dwellers could be much enhanced by providing access to modest technical and financial resources and by ensuring protection of fishing grounds. For this reason, transfer of existing technology between developing regions is accorded a high priority. The book itself makes a significant contribution to this process by outlining possible improvements in fishing boats and gear, methods of creating artificial reefs and deploying fish aggregating devices, techniques for developing coastal mariculture and ways of improving fish processing and preservation. The geographical spread of the book is wide, from algal turf mariculture in Antigua chorkor kilns in West Africa fish aggregating devices in Trinidad and Tobago to new boat designs in Western Samoa. Fisheries Technology for Developing Countries uses such examples to provide a comprehensive view of the technologies that can be deployed to improve fish harvesting and processing in the developing world. Its clear text presents the drawbacks as well as the advantages and, in all cases, the emphasis is on enduring improvements. As the authors point out, the advantages of out-board motors for fishing boats are obvious, but in West Africa the lack of foreign exchange to purchase spare parts, replacement motors and fuel has resulted in a decrease in the percentage of motorized small-scale fishing boats.
