Milkfish is a marine and brackish water species that is locally caught and eaten, but rarely has it been cultured commercially in ponds in the Western Indian Ocean Region. Milkfish farming is considered to have great potential to provide additional livelihood and food production opportunities for coastal communities in Western Indian Ocean Region. This guide provides an overview of low-cost, low-impact milkfish farming methods based on emerging lessons in adapting Asian production methods to the Western Indian Ocean context. New information presented in this guide is based on experience gained through trials aimed at developing commercial milkfish farming methods in Tanzania. The emphasis is on methods which are simple, locally appropriate and environmentally friendly.
