The roach ( Rutilus rutilus ) is a common freshwater fish species in the brackish coastal areas of the northern Baltic Sea. In this study, surveys of roach larvae were carried out at reed-belt shores encompassing the entire archipelago zone in the northwestern Gulf of Finland. A logistic regression model was constructed and then used to spatially predict and map potential roach reproduction areas using a geographic information system (GIS). The results indicate that low spring salinity (<4‰) is the most important factor determining the success of roach reproduction. Reed-belt shores in the inner archipelago with large freshwater inputs in the spring constitute the key reproduction areas. Spring runoff peaks caused by melting snow together with the effects of ice cover on the spreading of freshwater runoff enable roach to reproduce relatively far from river mouths. Nevertheless, 68% of the reed-belt shores in the study area are presently beyond the 4‰ salinity limit and thus unsuitable for reproduction. In the future, climate change is predicted to reduce the salinity of the Baltic Sea, but the potential climate change impacts on roach are partly contradictory. The most likely outcome, however, is a spatial increase in the extent of roach reproduction areas in the northern Baltic Sea.
