The historic and current knowledge of the occurrence of lake minnow, Eupallasella percnurus (Pall.) in Pomorskie Voivodeship in Poland is described. It considers factors threatening the existence of this species, and determines possibilities for the conservation and protection of sites which it inhabits. Currently, E. percnurus is known to inhabit 102 sites in the voivodeship, which constitutes 59.3% of all known sites in Poland (172). The main threats to E. percnurus sites and/or populations in Pomorskie Voivodeship include the draining and drying up of water bodies and their transformation for recreational use. Currently, only 10 of the sites are classified as threatened to a low level, while 44 sites are endangered to a high level. Almost half of all the sites (45) are subject to protection within the framework of the European Ecological Natura 2000 Network, and these probably have the greatest chance of survival
