Abstract
In Chwaka Bay, aquaculture (the farming of aquatic organisms) is represented
by a small-scale but much debated activity; farming of marine macroalgae, or
seaweed farming. Aquaculture as a whole dates back several millennia in areas like
South-East Asia, but has during the last decades become heavily promoted as an
alternative livelihood in developing countries to (i) reduce pressure on overharvested
natural resources (e.g. fish stocks) and (ii) supply cheap food and income
(Tacon 2001). Many promises of this “Blue Revolution” have, however, not been
fulfilled, because technical know-how and experience is often lacking (Dadzie
1992; Machena and Moehl 2001), and because some of the hitherto dominating
forms (for example farming of giant shrimp/prawns) have been riddled with huge
sustainability problems of their own (Deb 1998; Bryceson 2002).
