N2 - Within the KB35 program on food security and water the potential for sustainable food production from aquatic systems is investigated. In the past years the focus has been on the Indonesian archipelago, however a large question remains from the initial plan: what are the potentials for aquatic systems on a more global scale. In order to investigate this, suitable areas were selected where the obtained knowledge could be implemented. After this research it became clear that there is a large potential for aquatic systems in East Africa. In this work we explored the potential of disseminating the knowledge obtained in Indonesia. This was done by an extensive field visit to the islands Unguja (also known as Zanzibar) and Pemba as the mainland of Tanzania. Due to permit limitations it was not possible to visit many sites on the mainland, but all in all it became clear that the land is eager to find new ways of food production in a sustainable way. The methodologies and knowledge obtained in Indonesia are highly suitable to be implemented in this country. In addition, with many similarities in coastal systems between Indonesia and East Africa, the team foresees potential along a large part of the African coast to implement sustainable aquaculture methodologies. The knowledge to be implemented is sustainable, integrated extensive aquaculture in which two or more species are to be cultivated in either land based ponds, or enclosed areas in the coastal waters of the sea. Integrated aquaculture of seaweed with either shrimp or fish are considered to be the most promising combinations. The methods developed in Indonesia are low cost and easy to be deployed. Explementary is the extensive co-cultivation of shrimp (P. monodon) and seaweed (Gracilaria). Cultivation of these commodities provide food (shrimp) as well as an agaroid seaweed which can either be implemented in the existing practices of processing them into local products (food and cosmetics) or which could be exported. By doing this type of cultivation, no additional (imported) animal feed is required which is the main source of costs for farmers. A requirement is the availability of land on which ponds could be created and a supply of brackish water. Also there is the need for seedstock for the species to be cultivated (e.g. seaweed, fish, crustaceans and shellfish). This latter can be a challenge as these are not yet available and development of hatcheries and nurseries can be challenging due to the lack of expertise and the high costs.
