Book excerpt: Cage culture is an established and profitable aquaculture system in many countries but it is a relatively complex culture system that is still in its infancy in the Africa region. This expert workshop was convened with the aim of identifying the key issues for sustainable cage culture in the region and developing a framework of good management practice. It concluded that although cage aquaculture could be an important development opportunity, it will require an effective policy framework to ensure that structural constraints to development are overcome and that development is both equitable and sustainable.
