Macroinvertebrates of the Venta River have been studied since beginning 20th century. However, complex studies along from Latvian–Lithuanian border to its mouth into Baltic Sea irregular and fragmentary. The aim this study was assess ecological status analyze abundance fauna composition macroinvertebrates entire length river in territory Latvia. This is first kind for examining specialization sediment substrates their functional feeding groups. Within framework study, importance assessed 10 sampling sites together with quality using several indices. results show that dominated by benthic invertebrate collectors/gatherers, active filterers, grazers, scrapers adapted particular type sediments formed silt, macrophytes, rocks, pebbles. Different indices were calculated order River. According saprobity index, water corresponds β-mesosaprobity, while mostly average; however, according multimetric indices, varies poor high depending on station.
