What is it about?
Complex studies of seasonal differences of the ecological state of Masrik River (Armenia) were realized in 2017. Water quality was assessed by BMWP, ASPT and FBI indices based on studies of qualitative and quantitative structures of benthic macro-invertebrates. Potential reference sites in the basin were revealed using the %EPT taxa index in addition to water quality assessment by bioindication methods as well as hydro-chemical, -physical and -morphological measurements. The applicability of the used biotic indices for the different parts of Masrik River was discussed.

Why is it important?
River Masrik is one of the most important spawning rivers for endemic endangered fish species of Armenia - Sevan trout. Thus, the assessment of seasonal changes of its ecological state is of paramount importance for further assessment of its potential to support natural reproduction of Sevan trout
Perspectives
This work contributes in better understanding of current ecological state of River Masrik and allows to assess the potential of the river to support natural reproduction of Sevan trout.
