The Ecopath approach and software were used to construct a trophic model of the coastal fisheries ecosystem of the southwest (SW) coast of India. The model consisted of 11 ecological groups and used estimated landings from all areas along the southwest coast (based on the sample surveys conducted by Coastal Marine Fisheries Research Institute for the years 1994, 1995 and 1996). The trophic model suggests high catch levels, particularly for the large and medium predators, demersal feeders and detritivores.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is committed to improving the food security and wellbeing of poor people who depend on freshwater and coastal ecosystems for their livelihoods. AAS is particularly concerned with enhancing the equity of the social, economic and political structures that influence the livelihoods of poor households dependent on aquatic agricultural systems.
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.
A description is given of the Japanese muro-ami fishing gear, which although is very effective in catching elusivereef fish, causes considerable reef damage during its operation.
The Timor-Leste National Aquaculture Development Strategy (2012–2030) provides a framework for future responsible development of the aquaculture sector in the country. The strategy is anchored to the underlying principles of combating widespread poverty and malnutrition and for effective ecosystem management in the country. The development of the National Aquaculture Strategy involved consultation meetings with agro-ecological, social, economic, and institutional aspects.
This poster outlines the key steps in setting up a fish pond for tilapia farming in Solomon Islands, from making the pond to harvesting.
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.
The WorldFish Center was tasked to undertake a study to access, collate and develop background materials to produce an internationally linked and Africa-wide perspective on sectorally relevant policy issues.
Even in an increasingly polarized climate of global policy-making, the ideal of “sustainable development” retains currency across a remarkably broad swath of the political spectrum in debating alternative scenarios for the future. By adapting Weber's classic categories of value spheres and collective rationality, I distinguish contemporary approaches to operationalizing the concept of sustainability and elucidate the practical implications of each.
Rural households who fail to gain a voice in decisions over the management of shared forests, pasturelands, wetlands and fisheries face heightened risks to their livelihoods, particularly as competition increases between existing and new user groups. Exclusion from decision-making increases vulnerability of rural households, making it more difficult for them to move out of poverty and thwarting broader efforts to achieve sustainable resource management. Poor rural women in particular often face institutionalized barriers to effective participation in resource management.
