Concerns about perceived loss of indigenous materials emerged from multiple stakeholders during consultations to plan and design the CGIAR Research Program on Aquatic Agricultural Systems for the Borotse hub in Zambia’s Western Province. To come to grips with and address the concerns, the AAS Borotse hub program of work included an assessment of agrobiodiversity to inform community-level and program initiatives and actions.
ACIAR, in collaboration with the Secretariat of the Pacific Community (SPC), organised a symposium on tropical sea cucumber aquaculture at SPC Headquarters in Noumea, New Caledonia, in February 2011. Although the principal focus was on ACIAR work, particularly in the Asia–Pacific region, researchers from other parts of the world were invited to provide additional expertise. The symposium identified knowledge gaps and highlighted researchable topics for future developments in sea cucumber aquaculture.
The potential of aquaculture to reduce poverty and hunger has been recognised in Africa. However, growth in the sector has been limited up-to-now, providing less than 2% of total fish production. In Eastern and Central Africa, the slow growth has been caused by a number of factors, including a development focus on resource poor farmers rather than small and medium enterprises, a lack of focus on the entire fish value chain (feed, seed, processing and marketing), as well as weak governance and policy environments.
Farming-based rural livelihoods are becoming increasingly vulnerable to the effects of global climate change and sudden and profound changes in social and economic systems. Diversification of livelihood options is believed to be vital to maintaining ecosystem resilience and building social systems resilience. Integrated agriculture-aquaculture (IAA) farming systems, considered among the promising options for small-scale farming households in China and Vietnam, are likely be relevant in the context of mixed crop- livestock farming systems elsewhere as well.
The WorldFish Center conducted a review in Bangladesh funded by IFAD in 2011 on the present status of aquaculture production and fish consumption. This brief summarizes the key findings of the review.
The aim of this article is to compare two extremes of approaches taken to turtle culture projects. At one extreme is the capital-intensive operation aimed at realizing a profit, e.g., that of Mariculture Ltd. on Grand Cayman Island. At the other end of the scale is the small, village-industry operation which has been tried or is still being tested in several developing regions. While commercial viability may also be an aim of this latter approach, other considerations seem to be important in assessing success, e.g., the provision of employment.
Zooplankton are an important food source for many species of fish. They can provide an inexpensive alternative to other commercial feeds. Zooplankton have several advantages, among them a faster growth and greater feed efficiency for some species. The flavor and texture of fish are also improved with zooplankton as feed. Further research is needed on the chemical composition of zooplankton, the development of zooplankton-based dry diets and the effects of the replacement of fish meal with zooplankton meal for commercial aquaculture species.
This year's report contains the Director General's and Chairman's statements illustrating the major thrust of and progress with the approved 2011 strategy. It incorporates details of the financial statement for the past year. There are highlights from projects covering the enhancement of coastal fisheries, livelihood in the Philippines, programs on lake fisheries in Malawi, to capacity building in terms of long term training for local partners and stakeholders.
