A preliminary mass-balance trophic model was constructed for the coastal fisheries ecosystem of the West Coast of Peninsular Malaysia (0 - 120 m depth). The ecosystem was partitioned into 15 trophic groups, and biomasses for selected groups were obtained from research (trawl) surveys conducted in the area in 1987 and 1991. Trophic interactions of the groups are presented. The network analysis indicates that fishing fleets for demersal fishes and prawns have a major direct or indirect impact on most high-trophic level groups in the ecosystem.
A trophic model of Lake George, Uganda, Central Africa was constructed using published quantitative and qualitative information on the various biotic components of the lake and the ECOPATH II approach and software. It is shown that the available production and biomass estimates for the various groups in the system are consistent with each other, and that it is possible to make a balanced model of the major trophic interactions in Lake George.
Aquatic agricultural systems (AAS) are systems in which the annual production dynamics of freshwater and/or coastal ecosystems contribute significantly to total household income.
A brief history of the library programme offered to Librarian from developing countries was given.
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.
Following a brief description of lake-based hatcheries and nurseries for tilapias, the advantages as compared to land-based systems are discussed, indicating also some of the disadvantages.
This selected bibliography contains 343 references on various aspects of Tilapia. Arrangement of entries is alphabetically. Author, subject, taxonomic and geographical index is provided to facilitate cross-referencing.
