Sociological aspects in western Sudan relating to the development of fish farming are discussed as a means of supplementing the local diets.
The Food and Agriculture Organization (FAO) strategy for improving information on the status and trends of capture fisheries (FAO Strategy STF) was endorsed by Member States and the UN General Assembly in 2003. Its overall objective is to provide a framework, strategy, and plan to improve knowledge and understanding of the status and trends of fisheries as a basis for policy-making and management, towards conservation and sustainable use of resources within ecosystems.
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.
Localized changes in the productivity of marine and inland waters induced by climate change will pose new challenges to the fishery and the aquaculture sectors in West Africa. However, climate change does not occur in isolation of other drivers of change: processes of environmental, economic and social change can affect the fishery sector, potentially creating additional vulnerability to climate change. Scenarios are a useful tool to explore uncertainties and understand non-climatic drivers of change.
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 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.
A brief account of the evolution and structure of the marine fisheries of Senegal, West Africa, is presented, with emphasis on the small-scale subsector and on the major recommendations of an international symposium/workshop on this topic, held on February 1993 in Dakar.
This report is a compilation of five regional reviews that document the global status of tropical rivers and inland fisheries in three continents: Latin America, Africa and Asia. It explores the role of valuation methods and their contribution to policy making and river fishery management.
An investigation of fishermen’s knowledge of fish occurrence patterns on various spatio-temporal scales has been realized in the Fatala Estuary (Guinea, West Africa), accompanied by a one-year survey with standardized gill-net sets. Seventy one fishermen distributed in four zones corresponding to gill-net sampling sites were questioned about seasonal variations of species’ relative abundances. Longitudinal and seasonal patterns of fish relative abundances were described with correspondence analysis and ANOVA for both approaches.
A discussion is presented on the role played by women in artisanal fisheries in Africa, considering in particular their role in post-harvest activities. Although there are great differences from one country to another, the contribution ofwomen to the sector cannot be overemphasized; from landing the fish, to processing and selling in the market, the women are often in charge. The importance of the realization of this role played by women in the planning of development projects is stressed.
