In the 1980s global aquaculture production accounted for less than 10% of global fish production. However, it has grown exponentially over the last three decades. It is expected that farmed fish will supply 50% of food fish by the end of this decade. China has been at the forefront of this. Although much has been invested in aquaculture in sub-Saharan Africa, growth has been relatively disappointing in spite of strong market demand and high prices. However, there are examples, such as Nigeria and Ghana, where the aquaculture sector has taken hold. Malawi, on the other hand, has not experienced expected growth despite high demand and good natural competitive advantage.
