Sabretoothed thryssa

📖 Overview

A riverine and lacustrine species, but perhaps passing from estuaries into the sea. More data needed; rather few specimens are in museum collections . Often ascends into freshwater . Occurs in medium to large-sized rivers of the lower Mekong . Apparently non-migratory , but reported to undertake migrations in the Mekong mainstream . From the Khone Falls to the Mekong delta, it migrates upstream during the dry season from October to March and downstream at the onset of the monsoon season from May to July . These migrations are reported to be triggered by the receding or rising of the water levels . Feeds on crustaceans, insects and small fishes . Use to make prahoc .
