Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
Pristolepis fasciata is known to occur in large floodplain rivers to estuaries as well as lakes, ponds and swamps (Menon 1999). The species has been observed to be potamodromous, migrating from the Mekong River to the flood plains during the floods of the monsoon season and back to the river at the onset of the dry season (Sokheng et al. 1999).

Justification

Pristolepis fasciata is assessed as Least Concern in view of its wide distribution, presumed large overall population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The presence of this species in India is doubtful, based on genetic studies.
