Kurzfassung auf Deutsch: The 1999 Africa Regional Aquaculture Review (CIFA OP24), the 2004 report of the FAOWorldFish Center Workshop on Small-Scale Aquaculture in Sub-Saharan Africa: Revisiting the Aquaculture Target Group Paradigm (CIFA OP25) and the 2005 FAO Expert Workshop on Regional Aquaculture Review: Africa concluded that the availability of fish seed is one of the major constraints to aquaculture development in Africa. This constraint is in terms of both the quantity of seed available for producers as well as the quality of this seed. Until recently, the seed bar rier was principally with regard to the quantity available; many producers unable to gain access to enough seed to fully exploit their farms. Most of these affected farms were small, integrated family operations of the sort currently categorized as “non-commercial”. For these farmers, management and investment levels are low and higher quality (e.g. improved strains) seed would likely manifest little if any enhancement in yield and/or would be excessively expensive if available. However, within the past decade there has been a marked increase in investment in small- , medium- and large-scale commercial aquaculture in the Africa Region. These aquabusinesses, of all scales, are investing in good management; both human and biological. Such farms are using higher quality feeds, maintaining water quality and, in short, establishing conducive environments where improved strains could manifest their performance edge. Neverthel ess, such firms do not formally have access to improved tilapia strains and little research is underway to develop similarly improved catfish varieties. Given the growing competitiveness of national, intra regional and international markets, the central question for investors and would-be investors was how to have access to better performing culture organisms? The FAO Inland Water Resources and Aquaculture Service, through the Fisheries Department Group of the FAO Regional Office for Africa, convened a regional workshop that included private industr y, government resource managers, representatives from environmental ministries and conservation groups to address these important issues within a broad context of conservation and development. The workshop is also in response to articles of the FAO Code of Conduct for Responsible Fisheries 1 that requests that, “States should conserve genetic diversity and maintain integrity of aquatic communities and ecosystems by appropriate management”, and, “... promote the use of appropriate procedures for the selection of brood stock and the production of eggs, larvae and fry” (Article 9.3), as well as the Nairobi Declaration (Appendix H) that provides a framework for responsible use of genetically improved seed for aquaculture.
