Juveniles are typically euryphagous. They feed on planktonic and benthic organisms. Food spectrum narrows during migration from the river to the sea. Diet composition is determined by river conditions and by the hydrological conditions of the coastal region of the sea, particularly the water level in the river and the tide cycle, as well as illumination at night (Ref. 9027).
