Fish and macrozoobenthos were surveyed at 29 sites in summer 2007. The composition of macroinvertebrate assemblages in headwater in the upper B\u00EDlina river indicated clean water with saprobic index (SI) 1.3-1.4 followed by transitional stretch downstream the Kyjick\u00E1 reservoir (SI 2.1-2.3) and dramatic decline of water quality to SI 3.2 in the river stretch downstream of industrial and municipal pollution at Litv\u00EDnov-Z\u00E1lu\u017E\u00ED. Twenty three fish species were documented in all basin. Chub, gudgeon and roach were the most frequent species at the B\u00EDlina sites.
