Selective breeding in fish and conservation of genetic resources for aquaculture

To satisfy increasing demands for fish as food, progress must occur towards greater aquaculture productivity whilst retaining the wild and farmed genetic resources that underpin global fish production. We review the main selection methods that have been developed for genetic improvement in aquaculture, and discuss their virtues and shortcomings. Examples of the application of mass, cohort, within family, and combined between-family and within-family selection are given.

Review of environmental impact, site selection and carrying capacity estimation for small scale aquaculture in Asia

Asia is the leading aquaculture region in the world, contributing to 85% of total world aquaculture production. Of the top 10 aquaculture producing countries 9 are Asian with China accounting for more than 65% of Asian production. Aquaculture in Asia contribute more than 80% of an estimated 17-20 million aquaculture farmers in Asia providing livelihoods, food security and export earning power but at the same time there are growing problems with environmental impact from large numbers of small-scale producers and the difficulties in planning and management of further development.

Protecting small-scale farmers: a reality within a globalized economy?

Aquaculture is still the fastest-growing food-producing sector and plays an important role in enhancing global food security and alleviating poverty. Tens of millions of people are engaged in aquaculture production, the majority of whom are small-scale farmers who have limited resources and are faced with difficulties due to increasing globalization and the resultant trade liberalization of aquaculture products. Despite these challenges, small-scale farmers remain innovative and continue to contribute to global aquaculture production.

A practical guide for ex-ante impact evaluation in fisheries and aquaculture

This guide provides a framework for ex-ante evaluation of fisheries and aquaculture projects in developing countries. Ex-ante impact evaluations check the potential of a project or program to deliver benefits from proposed interventions. Providing extensive annotated literature citations, this guide is designed for use by practitioners who may not be fisheries or aquaculture specialists.

Overview of sea cucumber aquaculture and sea-ranching research in the South-East Asian region

South-East Asia has traditionally been the global centre of production of tropical sea cucumbers for Chinese markets. Early research into culture methods took place outside this region, notably in India, the Pacific region and China. However, recent investment in Holothuria scabra (sandfish) culture has led to some significant advances within this region. The Philippines and Vietnam have been at the forefront of recent efforts, with involvement from substantial national programs and local institutions as well as international donors and scientific organisations.

Out of the factory and into the fish pond: can certification transform Vietnamese Pangasius?

This chapter examines pangasius catfish aquaculture in Vietnam in the context of changing social relations of production, European consumer trends and regulation. In particular we are interested in how the rise of 'sociotechnical' environmental regulatory networks in the form of quality standards and third-party certififcation have altered power relations between consumers and producers across global space.

Multiple water use as an approach for increased basin productivity and improved adaptation: a case study from Bangladesh

This study, supported by the Challenge Program Water and Food (CPWF-Project 35), demonstrates the case of multiple-use of water through seasonal aquaculture interventions for improved rice–fish production systems in the Bangladesh floodplains. The project focused on community-based fish culture initiatives, increasingly adopted in the agro-ecological zones of the major floodplains of the Padma, Testa, and Brahmaputra basin. The productivity of water and fish is used as an indicator to explain this case.
