From March 2002 to May 2011 about a hundred water bodies in the Mazowieckie Voivodeship (Poland) were investigated with the goal of discovering new sites inhabited by the endangered cyprinid lake minnow, Eupallasella percnurus (Pall.). Ten sites were discovered that had been previously unknown. During the same period, six new sites were created by translocation of cultured juvenile individuals into suitable water bodies not inhabited by this species. These measures were undertaken as part of a long-term (2002-2015), voivodeship-wide program for the active protection of this species. Of the sixteen sites currently in existence, ten are suffering from advanced water basin shallowing and/or vegetation overgrowth. At present, five sites (31.3 percent of all sites in the voivodeship) are protected within the European Ecological Natura 2000 Network
