Northeastern Thailand (Isan) is one of the least developed areas in this economically fast growing country. Traditionally, rice farming is the most important source of income and rice is the staple food. Animal protein consumption in the remote areas still largely depends on hunting and collection of products like fish, snails and insects. Besides fisheries activities on the Mekong River and its tributaries, and fish harvests from ricefields and village fishponds, further potential for fish production has been created with the construction of small and medium sized reservoirs.
