This assessment set out to investigate why fish farming has spread in Tonkolili District yet been poorly adopted in neighboring Bombali District. The purpose was to analyze what was working in Tonkolili but not in Bombali and then extrapolate this beyond Tonkolili. The current study aims to consolidate the most recent FAO study and map out pond distribution in Tonkolili, the most popular aquaculture development district in Sierra Leone, while also trying to make sense of this distribution.
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.
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.
The roles of homestead ponds and surrounding dike production of vegetables on farms in peri-urban and rural communities in central north Bangladesh were assessed. The study supports the view that small homestead ponds can contribute to the wider food supply, and that such “quasi-peasant” forms of aquaculture contribute to reduced poverty and enhanced dietary diversity and food security in the broader population.
This guidebook details the technical steps to culturing fish in homestead ponds in Bangladesh. It is targeted at hilsa fishers in rural Bangladesh, who often have ponds where they can culture fish and fulfil their livelihood needs yet have insufficient knowledge about fish culture. The aim of the guidebook is to support fishers to develop an alternate income source and help them cope with the seasonal ban on hilsa fishing imposed by the government.
When fish have only access to formulated feed, the optimal dietary protein to energy ratio (P:E) for tilapia ranges between 18 and 23 g.MJ<sup>-1</sup>. In pond culture, where natural foods complement administrated feed, increasing the carbon:nitrogen (C:N) ratio stimulates the natural food productivity. This study assessed if lowering the dietary P:E ratio (and thus increasing the C:N ratio of the feed input in the pond) below the optimal P:E ratio affects fish productivity, food web dynamics and nitrogen balances in semi-intensively managed tilapia ponds.
Small indigenous species (SIS) of fish such as the mola carplet (Amblypharyngodon mola) are rich in nutrients, often containing high levels of zinc, iron, and vitamin A. Despite scientific and government efforts, culture of SIS for improved nutrition is not yet widespread. This paper investigates the contribution of the mola carplet, commonly referred to in Bangladesh as ‘‘mola’’ to household fish consumption, and the factors influencing productivity and income from carp–mola polyculture in southwest Bangladesh.
In Cambodia, fish provide a major source of animal protein for rural households. Capture fisheries have declined and aquaculture has been identified as playing an important role in food and nutritional security and rural income generation. In 2011, WorldFish, in partnership with the Stung Treng Fishery Administration Cantonment and the Culture and Environment Preservation Association, aimed at improving the uptake of small-scale aquaculture by communities with limited experience in fish culture in Stung Treng Province in northeast Cambodia.
Due to inadequate technical knowledge and training in advanced methods of gradually growing tilapia culture, framers are not getting expected yield. From the very beginning of the CSISA-BD project, WoldFish Center has taken initiative to introduce advanced methods in tilapia culture. To do this, the shortage of skilled trainers and training materials, has, particularly, been realized. Presently, a number of manuals on tilapia culture from Department of Fisheries, Bangladesh Fisheries Research Institute, WorldFish Center and different GOs and NGOs are available.
Due to lack of sufficient technical knowledge and training on improved rice-fish culture which is expanding every day, many farmers are not getting optimum results in production. World Fish Center, from the start of the CSISA-BD project took the initiative to develop guideline for improved system for rice-fish culture. It was felt that there is a lack of efficient and skilled trainers and appropriate training materials.
