Freshwater community-based aquaculture was introduced to village irrigation tanks in the dry zone of Sri Lanka in order to offset the limited supply of animal proteins available to residents in inland areas. As village irrigation tanks are common property resources (CPRs), community-based aquaculture demands collective action by farmer groups. This chapter shows that the values generated by aquaculture are not adequate to provide a major livelihood for all members of a given community. The sustainability of community-based aquaculture depends on the success of experimenting with institutional arrangements that can, on the one hand, minimize transaction costs and, on the other, achieve adequate returns for participants through productivity gains from tanks.
