The Programme for Integrated Development of Artisanal Fisheries in West Africa (IDAF) was initiated in 1983 to help some 20 coastal states from Mauritiana to Angola which wished to develop and manage their artisanal fisheries through participatory and integrated approaches. IDAF was initially financed by Denmark and Norway. The second phase of the programme which started in January 1989 and its third phase, July 1984 are entirely financed by Denmark through the Danish International Development Assistance (DANIDA).
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.
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.
Sociological aspects in western Sudan relating to the development of fish farming are discussed as a means of supplementing the local diets.
Fishing installations consisting of branches of trees, bushes or other soft vegetation stuck into the muddy bottoms of lagoons, lakes or rivers, are common throughout the world. Collectively, these may be termed "brush parks" and are found in many parts of west Africa, Madagascar, Sri Lanka, Bangladesh, Cambodia and China, as well as in Ecuador and Mexico. Two main types are common: (a) small, circular piles of branches sometimes surrounded by fences of more durable wood, and (b) larger, rectangular installations.
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.
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.
