N2 - A survey of deep pools in a certain part of the Mekong Delta, southern Vietnam identified
23 deep pools based on both local knowledge and bathymetric maps. Vam Nao areas with 3 deep
pools are important habitats for many Mekong species due to capture of large and important
fishes such as krempfi catfish (Pangasius krempfi, Pangasiidae); giant barb (Catlocarpio
siamensis, Cyprinidae); small-scale croaker (Boesemania microlepis, Sciaenidae) and soldier
river barb (Cyclocheilichthys enoplos, Cyprinidae). This indicated that Vam Nao deep pools are
critical habitats for Pangasius krempfi and other important fish species in the Mekong delta.
Important deep pools acting as refuge habitats or spawning habitats during the dry season should
be designated asfish conservation zonesto protect fish stocks. Moreover, fishing co-management
should be the good solution to effective management as fishing regulation enforcement is likely
impossible to apply in Mekong inland fisheries. In addition, quality and quantity of existing deep
pools have been affected due to increased silt deposition that resulted from dam constructions
and flood mitigation schemes. Hence, water management projects should assess their possible
impacts to the fisheries before implementing
