The Nutritious Pond System has now implemented its activities on the ground for a year. The project is a partnership between a research organization (WorldFish), universities (Wageningen University and Can Tho University), private sector firms (Nutreco, Skretting Vietnam, Vemedin) and shrimp farmers to develop a new approach to feeding pond aquaculture. This project Newsletter highlights recent activities and the first results of on-farm pond trials and outputs from fundamental research.
In the developing world, the majority of people who fish in inland areas do so primarily for subsistence needs. This suggests that survey or census questionnaires which collect information concerning the occupations of respondents will underreport the number of people who fish, and corollary to this, misrepresent dependence on fishing as a support service for food and supplemental income.
Rotational zoning systems (RZSs) have been applied as a spatial management tool for fisheries in developed countries. Fishing grounds are divided into numerous plots and assigned a cyclical periodicity for harvest. This is a distinct spatial management measure that differs from more common measures in the tropics, like periodic closures or marine protected areas. We find that biological prerequisites for rotational closures are tenuous for many tropical reef species, and they are likely to put stocks of threatened species at further risk.
To address the extreme food insecurity of the poor households in Bangladesh, WorldFish has designed a portable small pond which can hold fish in it and at the same time, provide water for horticulture. Trials began in 2014 when these 'WISH' (water and fish) ponds were distributed amongst selected rural 'pond-less' communities and semi-urban landless communities, and tested for integrated aquaculture and horticulture.
This selection of methods is based on lecture notes used at a FAO/DANIDA training course held in Mombasa, Kenya, in May-June 1980. The methods presented are: regression and correlation, estimation of growth parameters from length-frequency data, estimation of mortalities (total, natural, fishing mortality) and analysis of catch and effort data.
The WorldFish Center and FAO are implementing a regional programme entitled "Fisheries and HIV/AIDS in Africa; investing in sustainable solutions", funded by the Swedish International Development Cooperation Agency (Sida) and the Norwegian Ministry of Foreign Affairs. In Zambia, the main project site is Kafue flats. The Department of Fisheries (DOF) and National AIDS Council (NAC) are the main stakeholders who will utilize the results of the research to influence policy.
The stories included in this WorldFish Annual Report illustrate how change is inevitable and that with dialogue and shared understanding we can make a difference to the poor and hungry. The report shows the variety of approaches for achieving these goals set in early 2009, from adopting better aquaculture practices, to highlighting the nutritional benefits of eating fish, to strengthening community and ecosystem resilience and adaptive capacity.
To inform the development of alternative livelihoods, the women's traditional alok fishery in the Campo-Ma'an National Park and buffer zone of southern Cameroon were studied over 15 months. Participatory rural appraisal was used to characterise livelihood strategies among 45 households. Thirty-three cultured crops, nine farmed animal species and 65 non-timber forest products, including 31 bushmeat species are cultivated in, or harvested from, the forest. Transport is a major impediment to commercial trade of all local products.
An examination is made of the literature on giant clam (Tridacna ) culture methods induced spawning, larvae, larval and post-larval rearing and socioeconomics. ASFA and the ICLARM library and professional staff collections were used for the search.
