Abstract The distributions of three submersed macrophytes Najas marina, Myriophyllum spicatum and Zostera noltii were surveyed in the inner coastal lagoons of the German Baltic Sea. Growth and photosynthetic performances of these species were investigated in crossed laboratory experiments (salinity X irradiance). Z noltii showed the potential to grow in mesohaline lagoons, while N. marina seemed to be restricted to oligohaline areas. The potential distribution area of M. spicatum overlapped with those of the other two species. The laboratory results for N. marina and M. spicatum correspond with the recent distribution of the two species in the investigation area. However, neither historical nor recent distribution records of Z noltii match the potential of this species to grow at 3 and 8 psu. Potential depth limits were calculated for the three species at their collection sites. Accordingly, N. marina had the potential to grow at 0.9-1.1 m depth in the Saaler Bodden, M. spicatum at 1.1-2.1 m depth in the Gro ss er Jasmunder Bodden and Z noltii down to 2.5-5.1 m depth in the Salzhaff. N. marina grows maximally at 1.0 m in the Saaler Bodden, M. spicatum at 2.0 m in the Gro ss er Jasmunder Bodden and Z noltii at 3.0 m in the Salzhaff. Thus, recent and modelled historical values of all three species do not differ, and recent distribution limits do not indicate an eutrophication-induced decrease in depth distributions of these species at their respective collection sites.
