Aquatic agricultural systems (AAS) are systems in which the annual production dynamics of freshwater and/or coastal ecosystems contribute significantly to total household income.
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.
Currently many farming households face health and economic risks because of problems in malnutrition as a result of lack of knowledge and training, improved technologies and processes in farming. From the beginning of the CSISA-BD project, the World Fish Center has initiated introduction improved practices and technologies in rural farming to address malnutrition in farming households. In order to address the problem discussed, as a part of this project it has been felt there is a lack of skilled trainers and training materials.
The Mekong River Basin, site of the biggest inland fishery in the world, is undergoing massive hydropower development. Planned dams will block critical fish migration routes between the river's downstream floodplains and upstream tributaries. Here we estimate fish biomass and biodiversity losses in numerous damming scenarios using a simple ecological model of fish migration. Our framework allows detailing trade-offs between dam locations, power production, and impacts on fish resources.
The scoping mission team was composed of 14 people representing research institutions (RUPP), government (FiA, IFReDI), NGOs (ANKO, ADIC) and CGIAR institutions (WorldFish and Bioversity). The scoping trip was carried out over a 7-day period from April 28 to May 4 within eight (8) communities in Kampong Thom, Siem Reap, Battambang, Pursat and Kampong Chhnang. In addition, panel discussions were held with local government, fishery, agriculture and water management institutions, NGOs, the private sector and communities, and were convened in Siem Reap, Battambang and Pursat.
This study was carried out in order to understand the technical and economic characteristics of different Egyptian Nile tilapia (Oreochromis niloticus) hatchery systems. Hatchery operators at fifty tilapia hatcheries in four governorates were interviewed and four focus group discussions were held with 61 participants in March 2012.
Women are active participants in aquaculture supply chains, but a dearth of gender-disaggregated information hampers accurate understanding of their contribution. Research results and FAO National Aquaculture Sector Overview (NASO) fact sheets show that female participation rates vary by type and scale of enterprise and country. Women are frequently active in hatcheries and dominate fish processing plant labourers. Women’s work in small-scale aquaculture frequently is unrecognized, under or unpaid.
