Value-chain analysis: an assessment methodology to estimate Egyptian aquaculture sector performance

Egypt's aquaculture production (705,490 tonnes in 2009) is by far the largest of any African country and places it 11th in terms of global aquaculture production. The aquaculture sector in Egypt is now a mature one having developed over a period of more than 30 years, but the financial performance of the sector is not well understood or documented, even though value-chain analysis provides a methodological tool to do so.

Unconventional fishing methods in the Anambra and Imo River Basins, Nigeria

The Anambra and Imo River basins are richly endowed with fishery resources. The use of unconventional fishing methods, such as local poisonous herbs and chemicals and various explosives, threatens to destroy their aquatic resources. Some control measures to be taken are suggested in the following areas: education, patrols, cooperatives and legislation.

Two steps forward, two steps back: The role of innovation in transforming towards community-based marine resource management in Solomon Islands

In many coastal nations, community-based arrangements for marine resource management (CBRM) are promoted by government, advocated for by non-government actors, and are seen by both as one of the most promising options to achieve sustainable use and secure inshore fisheries and aquatic resources. Although there is an abundant literature on what makes CBRM effective, is it less clear how CBRM is introduced or develops as an idea in a community, and the process of how the idea leads to the adoption of a new resource management approach with supporting institutions.

Training manual on improved shrimp culture in Gher: A course manual for shrimp farmers

Due to inadequate technical knowledge and training in advanced methods of gradually growing shrimp 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 of shrimp culture in south-west of Bangladesh. To do this, the shortage of skilled trainers and training materials, has, particularly, been realized.

When co-management fails: a review of theory and lessons learned from reservoir fisheries in dry-zone of Sri Lanka

Over recent decades co-management has become an increasingly popular form of governance reform in many developing countries. Viewed as a means of promoting sustainable and equitable management of natural resources, it has seen wide application in small-scale inland fisheries. However, perhaps because of its worthy credentials, there has been insufficient critical assessment of the results. This paper commences with a review of underlying theory which is then used to explore the reasons for failure of a co-management initiative in Sri Lankan reservoir fisheries between 2001 and 2002.

Uniform tuna catch statistics in the Central and Western Pacific

In the vast central and western Pacific Ocean, collection of comprehensive fisheries statistics is complicated by the large number of nations and territories governing the waters of the region and the prominence of highly mobile vessels from distant water fishing nations in the exploitation of fish stocks. A regional approach to the collection of catch statistics is therefore essential.

A trophic ecosystem model of Lake George, Uganda

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.

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 household based pond aquaculture,homestead gardening and nutrition awareness

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.
