The inland fishery resources of Cambodia, originating mainly from the Tonle Sap Lake, rank first in the world for their productivity and fourth for their total catch. The floodplains' contribution to income, employment, and food security is higher than in any other country. However, the natural productivity of the Tonle Sap's floodplains will be threatened if the flood pulse, the temporarily submerged habitats, and the fish migration routes of the Tonle Sap Lake are not given attention. In relation to this, the influence of built structures, which modify the hydrology of the system, need to be better assessed in ecological and socioeconomic terms. A review of global research has shown these influences to be complex and very significant.
