Training in African aquaculture development.

The article focuses on the types of training needed in African aquaculture development. The author suggested that rather than needing less training, extension agents and others who operate in the idiosyncratic world of the poor African farmer, need a far deeper understanding of fish culture (particularly the basics of pond dynamics and ecology) than do those who can take advantage of industrialized-country infrastructure.

Time to reappraise rice-fish culture.

Rice-fish culture in Asia is discussed, examining reasons for the current decline in the practice. Factors of importance for a reappraisal of rice-fish culture and development of new technologies and management systems are described: 1) anticipated changes in rice agronomy implications for rice-fish culture; 2) fish production from deepwater rice ecosystems; and 3) raising herbivorous fish in rice fields.

WorldFish incubator: Sustainable aquaculture made possible

WorldFish Incubator is a new and innovative program designed to support investment into sustainable small and medium-sized aquaculture enterprises in developing countries. It identifies suitable projects and facilitates technical and financial assistance, offering nurturing in sustainable aquaculture through its network of contacts. By leveraging the benefits of scale, WorldFish Incubator will help the aquaculture sector deliver on its promise to meet the growing demand for fish whilst ensuring equitable supplies and access for the poor.

WorldFish

At WorldFish, we work with an extensive network of donors and partners to create change for the millions who depend on fish in the developing world. Partnerships are essential to bring technologies and innovations to scale and achieve development impact. By 2025, WorldFish, together with our donors and partners, will improve the lives of 28 million people.

Wind energy, hydropower and heat pumps for aquaculture

Wind and water power have a significant contribution to make to aquaculture and fish processing. Wind energy can provide mechanical power to operate pumps and aerators and can clso be used to generate electricity. Small-scalehydropower may be used to serve aquaculture in many ways wherever there is sufficient flow and fall of water. Additionally, refrigeration equipment and heat pumps may be driven by both wind and water power. The integration of these systems can serve energy needs in fish farming for processing, ice-making, mechanical power and electricity.

What shapes food value chains? Lessons from aquaculture in Asia

In this article, the authors explain what shapes food value chains through the analysis of selected aquaculture industries in four key Asian producing countries. Worldwide production of aquatic resources has grown rapidly in the past few decades, and aquaculture production in Asia has played a decisive role in this growth. They examine the main forms of coordination found along these value chains and the role that institutional frameworks play in governing them.

Water use at integrated aquaculture-agriculture farms: experiences with limited water resources in Egypt

Fish farming in Egypt is not formally recognized as an agricultural activity, so aquaculture cannot use water from irrigation canals. However, fish are raised as primary or secondary crops in combination with fruit and other plant crops. A study by the WorldFish Center found farms could efficiently use well water to intensively raise tilapia in aerated tanks and use the effluent to irrigate fruit trees, vegetables and flowers. Two other farms used water from nearby Nile irrigation canals to fill water storage reservoirs stocked with tilapia.

Vulnerability of mangroves, seagrasses and intertidal flats in the tropical Pacific to climate change

Mangroves and seagrasses are of special interest to coastal fisheries worldwide because of the role they play in providing nursery areas for commonly harvested fish and invertebrates. Although the ecology of fish and invertebrates associated with mangroves and seagrasses in the tropical Pacific is not well understood compared with other parts of the world, the connectivity among mangroves, seagrasses, intertidal flats and coral reefs indicates that mangroves and seagrasses throughout the region provide a similar function to such habitats elsewhere.

Value chain analysis of the aquaculture feed sector in Egypt

This study was carried out to evaluate the value chain performance of the aquaculture feed sector in Egypt, in terms of value addition, employment and profitability. The strengths and weaknesses of each link of the value chain were assessed and appropriate upgrading, management and development strategies were suggested. Quantitative data were collected for each link in the value-chain through structured questionnaires that were drafted and distributed to the key players in the sector; 25 fish feed mills and 34 fish farms covering different geographical and production regions.

Value-chain analysis: an assessment methodology to estimate Egyptian aquaculture sector performance

Egypt's aquaculture production (705,490 tonnes in 2009) is by far the largest of any African country and places it 11th in terms of global aquaculture production. The aquaculture sector in Egypt is now a mature one having developed over a period of more than 30 years, but the financial performance of the sector is not well understood or documented, even though value-chain analysis provides a methodological tool to do so.
