This edited book presents the emerging sustainable innovations in all areas of aquaculture in Africa with a view to create an opportunity whereby scientific outputs and recommendations can be endorsed for improved aquaculture outputs towards poverty alleviation and food security on the continent. Food insecurity and poverty are some of the challenges faced on the African continent. These challenges are further exacerbated by the growing human population and the impacts of climate change. Today, aquaculture has become one of the fastest food producing sectors in the world, with the potential to contribute significantly to food security and poverty alleviation in developing countries. In Africa, aquaculture is at an infant stage, however, many African countries have recognized the potential roles of aquaculture in food security, poverty alleviation and conservation of aquatic resources through their commitment to achieve the United Nation Sustainable Development Goals. The book reviews and synthesize research work from these thematic areas across Africa and provide a unique perspective on the emerging aquaculture innovations and illustrate how aquaculture practices could be feasible and cost effective while promoting social and environmental sustainability. The book also draws from global discussions on sustainable aquaculture practices and provides recommendations on what is feasible for Africa. This book is a great tool for the university students, scholars, aquaculture farmers, investors, and policymakers to understand the scientific based sustainable aquaculture innovations from an African perspective. This book is focused on SDG 2 and SDG 14.

Focus on issues related to SDG 2 and SDG 14 from Africa First book to present the latest scientific based aquaculture innovations emerging from Africa Covers diverse issues of aquaculture sustainability on the African continent
