Consumption of fish has increased rapidly over the past decades, particularly in Africa, and is likely to continue into the future (World Bank 2013). With a potential global shortfall in fish supply for direct human consumption of around 62 million metric tonnes by 2030, increasing attention is focused on the capacity of the global fish food system to meet demand (Hall and Schaffer 2015). Options for increasing the production of fish include wild capture fisheries and aquaculture production. The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment report predicts that the geographic ranges of many global marine species will change, that marine biodiversity will reduce in sensitive regions, and that this will affect fisheries productivity. Small-scale fisheries in coastal and inland waterways may similarly decline in the face of a changing climate, and land-use change (Welcomme et al. 2010). In particular, it is believed that aquaculture, in view of its resilience and adaptability and diversity of species cultured, will emerge as an alternative source of livelihoods for many.
