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.

This book presents key conclusions about the controversial killing of thousands of dolphins each year during tuna fishing in the eastern tropical Pacific. Dolphins drown in nets that are set to catch yellowfin tuna, which tend to swim beneath dolphin herds. After 20 years of intense debate among environmentalists, the tuna industry, and policymakers, this fatal by-product of tuna fishing remains a high-profile public issue. Dolphins and the Tuna Industry provides a neutral examination of the scientific and technical questions at the core of the problem. Recommendations for solutions are offered in two areas: developing new techniques that promise to reduce dolphin mortality with the existing purse-seine method of tuna fishing, and developing entirely new methods of finding tuna that are not swimming with dolphins. Dolphins and the Tuna Industry provides a comprehensive, highly readable overview of the dolphin-tuna controversy, useful to experts and newcomers to the issue. It explores the processes of tuna fishing and dolphin mortality, the status of the tuna industry, and the significant progress made in reducing dolphin mortality through modifications in fishing practice. The volume includes: An overview of U.S. laws and policies relating to tuna and dolphins. An illustrated look at how tuna fishing crews use their equipment, focusing on the purse seine, which is the method most economical to the industry but most deadly to the dolphins. An overview of what is known about tuna and dolphin populations and the remarkable bond between them. A step-by-step description of the fishing process and efforts to let dolphins escape from the nets. An analysis of possible approaches to reducing dolphin kill, including more stringent regulatory approaches and incentives for the tuna industry. This book will be indispensible to environmental and animal protection groups, tuna fishing crews and processors, companies that market tuna products, policymakers, regulators, and concerned individuals.

The international symposium "Tuna fishing and fish aggregating devices", October 1999, in Martinique, takes stock of the exploitation of large pelagic fish around FADs, based on regional synthesis for the three oceans and the Mediterranean Sea. Main themes include technology, fishing methods, impact on resources, biology of fish aggregation, anthropology and economic aspects of FAD exploitation.

Most organisms live in a seasonal environment. During their life cycles, some species face seasons of cold and heat, aridity and abundant rainfall, migration and stable residence, breeding and nonbreeding. Populations grow and decline as supplies of materials essential to their survival wax and wane. Such qualitative truths as these flow obviously from field observations. In this original monograph, Stephen Fretwell analyzes the highly complex interaction between a population and a regularly varying environment in an attempt to define and measure seasonality as a critical parameter in the general theory of population regulation. Concerned primarily with the size and the habitat distribution of populations, Professor Fretwell develops simple models that, when applied to specific populations, usually of birds, demonstrate the effect of seasonal variations on the regulation of populations. He maintains that seasonality, as a concept, is essential to a full understanding of environmental interaction. During the course of his exposition, the author offers several new hypotheses, including theories affecting the breeding, numbers, distribution, and diversity of wintering birds, and a theory affecting the body size of sparrows.

This book highlights recent developments in the field of computer simulation and its application to social dynamics and behaviour. It covers latest advancements in the use of agent-based modelling by focusing on thematic issues, methodological progress and applications, including policy, industry and business. It aims to promote this interdisciplinary type of research by showing synergies, complementary and integration especially between computer sciences, social sciences, economics and organization, often bridging qualitative and quantitative research. The primary audience of this book are academics, practitioners and professionals using computer simulation for business counselling or industry.
