Aquaculture for both finfish and shellfish is expanding rapidly throughout the world. It is regarded as having the potential to provide a valuable source of protein in less developed countries and to be integrated into the farming systems and livelihoods of the rural poor. This book addresses key issues in aquaculture and rural development, with case studies drawn from several countries in South and South-East Asia. Papers included cover topics ranging from production and technical issues (such as pond culture and rice field fisheries) to social aspects and research and development methodology. The book has been developed from a meeting of the Asian Fisheries Society. It is aimed at all concerned with aquaculture and rural development.

This book presents the management of agriculture and how paddy-cum-fish culture started in the Ziro valley. The brief introduction of geographical and socio-economic profile of Ziro valley is made to see how it has evolved over the years. Analytical study is also made on development of fish farms, area under paddy-cum-fish culture, production of fish and fish nurseries in Ziro valley in particular and Arunachal Pradesh in general. It also highlighted the organic and sustainable management of land, water and forest resources for the livelihood of rural populace since time immemorial. The author identified 14 indigenous strains that are cultivated in the agriculture of Ziro valley with diverse characteristics and varying in yielding rate. Moreover, the cost-benefit analysis of various indigenous economic activities including paddy-cum-fish culture of the farmers are done for ascertaining the economic viability and sustainability of the long practiced paddy-cum-fish cultivation by the Apatanis in Ziro valley.

Integrated farming in Asia is either considered an eco-friendly good that should be preserved for environmental reasons or a poor practice that will soon be superseded by industrial aquaculture. This report finds that most livestock-fish integration is sound business conducted by entrepreneurs accessing urban markets where the price of fish is relatively low. It can be used as part of a strategy to reduce environmental impacts of intensive livestock production and to produce low-cost food. Farmers have proved adept at both developing their systems to meet their own needs and diversifying the role of ponds, fish and livestock within their complex livelihoods.

Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.

This book is divided into three sections. Following the "Introduction", the second section, "Sustainable Aquaculture", offers integrated information on rice cultivation and aquaculture that provide additional benefits to producers. In addition, the participation of aquaculture in the restoration of the Crassostrea virginica fishery is evaluated. The third section, "Homeopathy and Probiotics", is about highly diluted substances and beneficial microorganisms that have proved their effectiveness in human medicine, agronomy, veterinary and currently in the marine aquaculture field. Also, a study focused on the performance of growth and nutrient utilization of the freshwater shrimp Macrobrachium vollenhovenii fed diets supplemented with Lactobacillus acidophilus is presented. This book can be consulted by students, professors and researchers in the area of biological sciences.

Published in three other languages and growing, Managing Biodiversity in Agricultural Ecosystems takes a look at how farmers manage, maintain, and benefit from biodiversity in agricultural production systems. The volume includes the most recent research and developments in the maintenance of local diversity at the genetic, species, and ecosystem levels. Chapters cover the assessment and farmer management practices for crop, livestock, aquatic, and associated diversity (such as pollinators and soil microorganisms) in agricultural ecosystems; examine the potential role of diversity in minimizing pest and disease pressures; and present studies that exemplify the potential nutritional, ecosystem service, and financial values of this diversity under changing economic and environmental conditions. The volume contains perspectives that combine the thinking of social and biological scientists. Inappropriate or excessive use of inputs can cause damage to biodiversity within agricultural ecosystems and compromise future productivity. This book features numerous case studies that show how farmers have used alternative approaches to manage biodiversity to enhance the stability, resilience, and productivity of their farms, pointing the way toward improved biodiversity on a global scale. As custodians of the world's agricultural biodiversity, farmers are fully invested in ways to create, sustain, and assist in the evolution and adaptation of a variety of plant and animal species. Thus this text is mandatory reading for conservationists, environmentalists, botanists, zoologists, geneticists, and anyone interested in the health of our ecosystem.

This technical document has been developed in recognition of the increasingly diverse demands for water from irrigation systems and the need to introduce more holistic land uses into conventional irrigation management. Despite historical precedents and efforts in the twentieth and early twenty-first centuries, the potential for the integration of fish production (capture fisheries and aquaculture) and irrigation systems has yet to be fully realized. Capturing these underutilized opportunities for the integration of fisheries and aquaculture could significantly increase local economies, food security, household incomes and livelihood diversity within irrigated agriculture systems. To re-examine the potential of fisheries in irrigation systems, the concept of the extended command area (ECA) is used, expanding the conventional definition of an agriculture irrigation command area. The reason for this expanded definition is because all elements of an irrigation system, from upstream dam storage to downstream drainage areas, offer opportunities for increasing fish production. Many of these opportunities may be realized at no additional cost to the main irrigated crop. This document provides an introduction to the ways fisheries and aquaculture already co-exist with irrigation and explores the threats and opportunities that arise from this. A key concept for sustaining and enhancing inland capture fisheries is “connectivity”– a fundamental basis for ensuring adequate environmental conditions to allow fish to flourish within an aquatic ecosystem such as a river, lake, or wetland. Improving connectivity within an ECA can restore elements of ecological services that may have been compromised or degraded through irrigation, water management or through other rural infrastructure development such as road construction. Practical application of the integration of fisheries and irrigation systems is explored through the use of the Ecosystem Approach to Fisheries (EAF) in the context of irrigation systems. The proposed process links the development of an EAF management plan for fisheries to irrigation system operation and is given the acronym EAFm-i. A key part of this linkage is an assessment of water resources in the system and the management of water for delivery to fisheries. Additional tools to support the EAFm-i process are also described. Although the experience and approach are drawn largely from irrigation systems and inland capture fisheries in Southeast Asia, the application of the ECA concept and approach will be relevant to any irrigation or water management system where there is potential for the closer integration and harmonization of fisheries and irrigation systems and where water users are interested in realizing this potential. This short paper is intended to encourage fisheries and irrigation specialists to engage in greater dialogue and cooperation over the integration of fisheries into irrigation planning and to support piloting of an EAFm-i process, which can be the basis for further development.
