The geography of the country predisposes the development of inland fisheries. Cambodia is crossed from north to south by a large alluvial plain, created by the Mekong River. In addition, the Tonle Sap River joins the Mekong River at the Great Lake. Most of the remaining output is from the Mekong Delta southeast of Phnom Penh. Fishing gears used are mainly passive types, mostly of net or bamboo, but hooks are also used.
Fishing gear is controlled in accordance with Cambodian fisheries law.
