This document is part of a series of 5 technical manuals produced by the Challenge Program Project CP34 “Improved fisheries productivity and management in tropical reservoirs”. The Water Research Institute (WRI) in Akosombo, Ghana, is working to bring cage aquaculture technology to smallholder farmers. The stocking, feeding and cage-construction technology piloted by WRI is now being widely adopted in the Lower Volta basin in Ghana. The results of WRI research over the period 2005-2009 are presented here as a guide to potential investors.
Pseudotolithus typus and P. senegalensis (Sciaenidae) sampled off Cameroon Coast, West Africa, have been found to feed mainly on shrimps (Nematoplaemon hastatus and Parapenaeopsis atlantica) and juvenile fish (mostly clupeids). The diet composition is presented and discussed.
This bibliography is intended for people who are involved in fisheries, aquaculture, climate change, disaster management and policy development in West Africa or interested in one or more of these issues. The literature in this bibliography includes peer-reviewed journals, books and book chapters, grey reports and institutional technical papers, but is restricted to literature in English. Each citation also includes an abstract.
This report presents the activities and results of the workshop Envisioning 2050: Climate Change, Aquaculture and Fisheries in West Africa. The objectives of the workshop were to discuss critical issues and uncertainties faced by the fisheries and aquaculture sector in Ghana, Senegal and Mauritania, build sectoral scenarios for 2050 and discuss the implication of these scenarios in the context of climate change for the countries and the region.
In contrast with the previous view, which placed the State as a central element for economic development and progressive social changes, the current literature on development now advocates the role of civil society and community participation and tends to assume that decentralization has generic benefits for sustained improvements of the living standards of people. The most common argument is that decentralization is by definition a mechanism of ‘inclusion’ and ‘empowerment’.
Relying on experience from West Africa and the Mekong Basin, the authors contend that small-scale inland fisheries are a critical element in the livelihoods of many farming households who live near water bodies in developing countries. Empirical evidence suggests that the relation between poverty and small-scale fisheries cannot be reduced to a simple correlation with income. A more thorough analysis is required.
