The trochus resource in New Caledonia

New Caledonia, which is surrounded by one of the largest lagoons in the world, is a good reservoir of the Pacific species of trochus (Trochus niloticus). The shell of this large marine gastropod yields one of the thickest, most beautiful mother-of-pearls available on the world market.

Transformative change in the CGIAR research program on Aquatic Agricultural Systems

The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is increasingly using the language of transformation to describe its aims and approach to achieving lasting impact at scale. Clarity on what AAS means by “transformation” is important to ensure that use of the term is intentional and meaningful. AAS wants to avoid the risk befalling a number of terms used in the development field-i.e., empowerment and participation-which are applied by such a wide range of actors with divergent intent and ideology that the terms lose meaning.

Training manual on improved tilapia culture and dyke cropping in pond/Gher

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.

Third world aquaculture and the environment

Aquaculture systems in developing countries are examined considering their environmental impact as well as benefits for producers. Extensive, semi-intensive and intensive systems are examined. Destruction of the naturalenvironment and ecosystem, pollution effects and detrimental effects of introduced species are among some of thenegative aspects of aquaculture development that have to be considered when setting up development projects.

Technical characteristics and economic performance of commercial Tilapia hatcheries applying different management systems in Egypt
