From the Greek syrtos - washed, applied and on - being.

Sirton is a collection of organisms carried by the current. In English-language literature, sirton is understood as "drift".

Drift, benthic forms that float up into the water column and are carried away by the current. The term "sirton" is close to the term benthostock. They are sometimes considered synonymous.

Sirton refers to the totality of all living organisms in the pelagics of standing and flowing waters, but not pelagic at this stage - these are representatives of benthos, periphyton, and neuston. They entered the water column as a result of changes in hydrochemical, hydrological conditions and due to behavioral reactions of hydrobionts.
