This paper assesses factors influencing adoption of new shrimp aquaculture technologies within aquatic-agricultural farming systems in southwestern Bangladesh. The impacts of three new technologies were assessed: two Modified Traditional Technologies (MTT 1 and MTT 2) and a Closed System Technology (CST). A total of 789 farmers from 10 sub-districts in Khulna Division were surveyed randomly, including a control group of 350 farmers using traditional technologies.
The present study was carried out to compare the production performance of white fish from traditional and modified traditional culture system in Patuakhali with the following objectives: 1) To know the production performance in traditional and modified traditional culture systems. 2) To observe the economic feasibility of two culture methods 3) To find out the effect of stocking density on survival and production in different culture system. 4) To know the socio-economic status of the fish farmers involved in both culture system.
Two sustainable, low-cost pond polyculture technologies have been developed to culture carps and mola in ponds, and culture carps and mola in ponds connected to rice fields. These technologies can increase total fish production from ponds. Farmers depend on carps as an income source, and mola is rich in micronutrients that can help to meet the nutritional requirements of the rural poor, particularly women and young children.
The IEIDEAS project, funded by the Swiss Agency for Development and Cooperation and managed by WorldFish and CARE in collaboration with the Ministry of Agriculture and Land Reclamation, has focused on the development of the Egyptian aquaculture value chain. In 2011, SDC and WorldFish conducted a value chain assessment.
We use global value chain (GVC) theory to understand governance of Vietnam’s shrimp farming industry. We describe this GVC as buyer-driven with important food safety standards imposed by governments of importing countries and new certification systems promoted by nongovernmental organizations (NGOs). Governance relations are clear between governments in importing countries and Vietnam, and between importers and NGOs. Governance relations become more fragmented further down the chain where large numbers of small-scale producers and traders operate.
Fisheries and aquaculture policy for education, research and extension is derivatives of the main national agriculture policy. Fisheries and aquaculture is a dynamic sub-sector of agriculture sector having high growth potential but with low organizational stature in Nepal. The modern aquaculture along with fisheries practices contributes nearly 1% of Gross Domestic Production (GDP) and 2.68% of Agriculture Gross Domestic Production (AGDP).
Since March 1987, there has been an experimental fish farmers cooperative near Bangui, in the Central African Republic. Its objective is to increase the productivity of existing ponds: currently 2-3 mt/ha/year. Previous attempts to expand aquaculture (mainly pond culture of tilapia) in the country have had limited success, principally because the use of small ponds meant that individual farmers could not buy fertilizers and fish food in big quantities and therefore at lower prices. Moreover, the costs of guarding each pond were too high.
The findings are presented of a survey conducted in Malawi to determine the acceptability by fish farmers of raisingfish in excreta-fed ponds. The use of livestock excreta appeared to be acceptable to the majority of farmers, whereas the use of human excreta was not. Various recommendations are made regarding the promotion of the use of excreta in small-holder farms.
This paper synthesises the main findings about the impacts of a wide range of farmer-led research initiatives in terms of food security, ecological sustainability, economic empowerment, gender relations, local capacity to innovate and influence on ARD institutions. It then draws lessons for future partnerships between formal and informal ARD actors who are seeking common goals in serving smallholder communities.
The participation of farmers in the research process related to the development of integrated farming processes is discussed with respect to observations made on the Mekong Delta in Vietnam. The use of drawing pictures of integrated agriculture-aquaculture systems as a means of helping both farmers and researchers to learn from each other in order to improve systems is noted.
