The study was carried out in 6 stations placed in the Lake Snagov, in 2011-2013. The aim of the study was to assess the state of ichthyofauna in this area relative to the reference data. Quantitative and qualitative analysis of Snagov ichthyofauna was made. During the fieldwork for the study of fish fauna, preliminary results indicate the presence of 19 species of fish in Snagov natural protected area. Comparing the present situation with the one from 1999-2001 period we observed a drastically reduction of fish populations and even the disappearing of some fish species, especially the ones that were used for industrial purposes.
