Use of genetically improved and alien species for aquaculture and conservation of aquatic biodiversity in Africa

Aquaculture species are being domesticated and improved through genetic enhancement. Despite the benefits of improved fish in terms of increased production, there are risks associated with conservation of biodiversity when the introduced strains/species escape in natural waters. This is especially important in Africa which is one of the world’s repository of diverse freshwater fish fauna and home to native tilapias.

Training resource book on a participatory method for modelling bioresource flows.

This guidebook helps researchers and extensionists learn an easy rapid appraisal technique that enables farmers to draw conceptual models of their farm systems. The drawings help researchers and extensionists to understand quickly local agricultural practices and identify entry points for integrating new enterprises into the farm. The book can be used independently or to accompany two videos, Aquaculture and the Rural African Farmer and Pictorial Modelling: A Farmer-Participatory Method for Modelling Bioresource Flows in Farming Systems.

Towards policies for conservation and sustainable use of aquatic genetic resources.

Genetic stock identification is increasingly needed for fisheries management. Genetic technologies are being developed to increase food production from aquaculture and to document and evaluate aquatic species, subspecies and strains for use in breeding programs. This volume of proceedings is a compilation of state-of-the-art reviews on aquatic genetic resource issues and summaries of discussions and recommendations from one of the few “think tanks” focused on aquatic genetic resources policy.

The Third International Symposium on Tilapia in Aquaculture.

Tilapias, because of the low cost and relative ease of their production, are a potential food fish staple for many people in tropical countries and a globally traded commodity. This volume of symposium proceedings shows a strong interest in production systems research and a dawning interest in socioeconomic research. Both of these fields of research are expected to receive much greater attention in the future as the economic and market importance of tilapia increases and as we seek to understand better the distribution of benefits of the different production technologies.

Strategies and options for increasing and sustaining fisheries and aquaculture production to benefit poorer households in India

Fisheries sector in India has made rapid strides in recent years. Its role in increasing food supply, generating job opportunities, raising nutritional level and earning foreign exchange has been continuously increasing. However, this sector did not receive adequate attention from the social scientists to understand its various socio-economic dynamics. This publication is an outcome of the research project on "Strategies and options for increasing and sustaining fisheries and aquaculture production to benefit poor households in Asia" in which India is one of the partners.

Strategies and options for increasing and sustaining fisheries and aquaculture production to benefit poorer households in Asia, ADB-RETA 5945: project completion report (appendixes)

The last three decades have witnessed dramatic changes in the structure of supply and demand for fish, especially in Asia. This WorldFish research study sponsored by the Asian Development Bank focussed on nine developing countries – Bangladesh, China, India, Indonesia, Malaysia, the Philippines, Sri Lanka, Thailand, and Vietnam, all active players in the transformation of global fish supply and demand. This document is the appendix to the main study.

Stock evaluation and development of a breeding program for common carp (Cyprinus carpio) in Karnataka, India: progress of a research project

Common carp (Cyprinus carpio) is the single most important species for aquaculture in the state of Karnataka, India, where it is generally grown in polyculture with Indian major carps. Precocious maturation and unwanted reproduction in the species have been identified as constraints to increase production in aquaculture and culture-based fisheries in Karnataka state. Stocks of C.
