composition of the wild capture fisheries, but that the risks
are fewer with indigenous species than with alien species
(MRC 2003). The MRC has shown that indigenous fish can
have a high market demand and value (Figure 1), and that
moreover, farmers and local consumers prefer them. The

MRC is actively working to preserve the rich biodiversity of
the Mekong and respond to the requests of their member
countries through the AIMS program. The MRC plans to
continue promoting indigenous aquaculture is as a
complement to healthy inland capture fisheries.
