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.
This paper deals with a number of case studies that were undertaken during the last 8- 10 years in utilizing divergent ‘Tal’ wetland ecosystems (deep, semi-deep, temporary in a range of agro-ecological zones like NAZ, OAZ and Coastal Zone of the region) for the development of integrated management programmes using a range of approaches.
Aquatic agricultural systems (AAS) are systems in which the annual production dynamics of freshwater and/or coastal ecosystems contribute significantly to total household income.
The current status of tilapia culture in Sudan is examined, describing the pond culture system used. Future prospects are also examined. It is believed that great effort is required before fish farming can boost food supply inthe country.
This report is a deliverable under the Terms of Reference – SmartFarm M&E Framework Development, dated June 2013. The purpose of this report is two-fold. Primarily, to set out a monitoring and evaluation (M&E) framework and strategy for the World Fish Center’s SmartFarm project. Secondarily, to link this framework and strategy to the wider CGIAR Climate Change, Agriculture and Food Security (CCAFS) Project and Aquatic Agricultural Systems (AAS) program, under which SmartFarm is a key component, as well as to existing World Fish M&E approaches.
Over the years, aquaculture has developed as one of the fastest growing food production sectors in Nepal. However, local fish supplies have been extremely inadequate to meet the ever increasing demand in the country. Nepal imports substantial quantities of fish and fish products from India, Bangladesh, Thailand, and elsewhere.
The Program will achieve impact at multiple scales (household, community, province and national as well as amongst program countries) through pathways that include partnerships, knowledge sharing and learning. In Solomon Islands significant benefits will be achieved through direct engagement with partners, including communities in specific research sites in selected program hubs. Of a total population of just over half a million people, 75% of Solomon Islanders are subsistence-oriented small holder farmers and fishers.
The need to adapt to climate change is now widely recognised as evidence of its impacts on social and natural systems grows and greenhouse gas emissions continue unabated. Yet efforts to adapt to climate change, as reported in the literature over the last decade and in selected case studies, have not led to substantial rates of implementation of adaptation actions despite substantial investments in adaptation science. Moreover, implemented actions have been mostly incremental and focused on proximate causes; there are far fewer reports of more systemic or transformative actions.
Effective partnership is central to the CGIAR Research Program on Aquatic Agriculture Systems (AAS). We recognize that many organizations are working to improve the lives of people living in aquatic agricultural systems, and together they spend hundreds of millions of dollars there each year.
This paper presents a tentative estimate of the parameters L8 and K of the von Bertalanffy growth function, and an estimate of total mortality derived from the analysis, using the ELEFAN I and II programs, of length-frequency data on the snapper Etelis carbunculus (Lutjanidae) collected on seamounts of the Kingdom of Tonga, South Pacific.
