Records of mysids in the Middle Danube (ordered by river km-s). PL: Paramysis lacustris (Czerniavsky, 1882), KW: Katamysis warpachowskyi G.O. Sars, 1893, LB: Limnomysis benedeni Czerniavsky, 1882. River km-s of sampling points in sidearms represent the nearest point in the main channel. Country codes: AT: Austria, SK: Slovakia, HU: Hungary, HR: Croatia. Since the samples were collected during the day, they cannot be regarded as representative for the nocturnally active Hemimysis anomala (G.O. Sars, 1907). The sampling was not quantitative; therefore, the numbers of collected specimens serve as only a rough indication of the relative densities of the three mysid species.
