Abstract

Cage aquaculture is expanding on the African Great Lakes (AGL) and has potential to provide the much needed nutritious protein, employment, income and export earnings.  It however, needs appropriate technical guidance and regulation to avoid conflicts with other water uses, environmental degradation, and economic losses.  We developed a database of cage aquaculture installations on African inland waters to ascertain its magnitude by integrating location and spatial data, and explored adherence of the installations to the Ecosystem Approach to Aquaculture.  This was supplemented with literature and experiences from other regions to develop generic best management practices (BMPs).  Cage aquaculture is expanding in Africa but requires: Proper guidance before starting; Selection of suitable and capable sites; Suitable farm plan; Appropriate design and installation; Application of appropriate culture practices; Marketing strategies; and Environmental monitoring.  There is also need to adhere to regulations and to improve them to adequately address the BMPs.  The proposed BMPs are adaptive, and will be improved from lessons learned from research and operations. NaFIRRI, with partners in the AGL region are enhancing the BMPs through awareness raising tools including a mobile application.
