WorldFish annual report 2011/12

This year's report contains the Director General's and Chairman's statements. Also highlighted in the reports, are stories of projects with different partners: 1) CGIAR Research Program on Aquatic Agricultural Systems (AAS) in Zambia. 2) Wetland Alliance project in the Mekong delta. 3) Projects with CARE, the humanitarian organisation in Egypt. 4) Tilapia breeding program with Water Research Institute (WRI) in Ghana. 5) Partnerships with the private sector on sustainable aquaculture enterprise in developing countries.

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.

Vulnerability of aquaculture in the tropical Pacific to climate change

In this chapter, the authors assess the vulnerability of aquaculture in the tropical Pacific to climate change. It begins by summarising recent and potential aquaculture production to set the scene for the sector, and then use the framework outlined in Chapter 1, based on exposure, sensitivity, potential impact and adaptive capacity, to evaluate the vulnerability of the main commodities for food security and livelihoods.

Value chain analysis of the Egyptian aquaculture feed industry

The commercial aquaculture feed industry in Egypt is growing at a rapid rate. As a result, the number of fish feed mills has increased from just 5 mills producing about 20,000 t per year in 1999, to over 60 mills with a current production estimate of 800,000–1,000,000 t/year. The performance of the aquafeed industry in Egypt is not well understood, as the value chain structure has not yet been mapped.

Value-chain analysis of Egyptian aquaculture

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 production. The aquaculture sector makes a significant contribution to income, employment creation and food security in the country, all of which are national priority areas given low per capita income levels, rising population, worsening food security indicators, and official unemployment levels which have remained at around 10% for the last ten years.

Uganda aquaculture value chains: strategic planning mission: summary report

This report presents the findings and recommendations of a strategic planning mission to reevaluate the feasibility of WorldFish implementing a fish value chain research program in Uganda under the CGIAR Research Program on Livestock and Fish (L&F). The over-arching goal of L&F is to increase productivity of small-scale livestock and fish systems so as to increase availability and affordability of meat, milk and fish for poor consumers and, in doing so, to reduce poverty through greater participation by the poor along animal source food value chains.
