Fisheries and fish supply are undergoing a fundamental structural transition, as indicated by a ten country analysis. Aquaculture now provides around half the fish for direct human consumption and is set to grow further, but capture fisheries continue to make essential contributions to food and nutrition security throughout the global South. Capture fisheries provide diverse, nutritionally valuable fish and fish products which are often culturally preferred and easily accessed by the poor.
This working paper is an attempt to distil what is known currently about the likely impacts of climate change on the commodities and natural resources that comprise the mandate of CGIAR and its 15 Centres. In this WorldFish contribution, a summary is given on the importance of fisheries and aquaculture on food nutrition and security.
The results are presented of a 2-year study conducted regarding management practices and problems associated with raising fish in concrete tanks in Nigeria. The location and construction of the tanks, which were used toculture Clarias gariepinus, Tilapia guineensis and Heterobranchus bidorsalis , are described, and suggestions made for overcoming the problems involved, which were mainly due to poor management skills. Major problems identified included incidence of "broken skull" disease in C.
The Feed the Future Aquaculture project is a five year transformative investment in aquaculture focused on 20 southern districts in Barisal, Khulna and Dhaka divisions, Bangladesh. This report describes the achievements of FtF-Aquaculture project activities implemented during FY12. Some of the targets for production and associated income have not been achieved yet as a large share of the fish will be harvested after closing of the reporting period. However, on the basis of growth monitoring, indications are that production is on track to achieve the targets.
Fish is crucial to food and nutrition security in Solomon Islands, and demand is expected to increase due to a growing population. However, it is projected that current capture fisheries production will not meet this growing demand. Aquaculture has the potential to mitigate the capture fishery shortfall, and the Government of Solomon Islands is prioritizing aquaculture as a solution to meet future food and income needs. Aquaculture in Solomon Islands is still in early development.
Bangladesh has made considerable progress against human development indicators in recent years, but malnutrition resulting from poor dietary diversity and low micronutrient intakes remains entrenched. Fish is central to the Bangladeshi diet and small fish species are an important micronutrient source. Although fish consumption per capita has increased in recent years as a result of rapid expansion of aquaculture, it is likely that consumption of fish from capture fisheries (including small indigenous species particularly rich in micronutrients), has declined.
Increases in fish demand in the coming decades are projected to be largely met by growth of aquaculture. However, increased aquaculture production is linked to higher demand for natural resources and energy as well as emissions to the environment. This paper explores the use of Life Cycle Assessment to improve knowledge of potential environmental impacts of future aquaculture growth. Different scenarios of future aquaculture development are taken into account in calculating the life cycle environmental impacts.
There are increasing requirements for impact assessment by development partners in order to increase the accountability and effectiveness of research and development projects. Impact assessment research has been dominated by conventional economic methods. This context challenges agricultural research organizations to develop and apply alternative impact assessment methods incorporating economic, social, and environmental impact components.
This report summarizes the results of a systematic effort to explore possible futures for aquaculture and fisheries in Indonesia. The work described is part of a larger effort that seeks to develop a shared vision for the sectors that 1) aligns public and private investments to foster growth and economic sustainability; 2) reduces environmental impacts and improves efficiency; 3) increases access by small and medium enterprises to the financial and technical assistance necessary to transition to more sustainable practices.
International investments in agroindustry present a growing source of tension for local populations who rely on land, forests, water and fisheries for their livelihoods, particularly where local tenure security is put at risk. For governments, civil society organizations and the communities directly affected, engaging the private sector early is critical in order to avoid an escalation of conflict and to build collaboration that can yield dividends for all. Yet care must be taken to address power differences among actors and to avoid manipulation by individuals or interest groups.
