Abstract
Simple morphological characteristics and fish assemblage data were col lected in representative numbers from 12 inland waterways in the north eastern lowlands of Germany between 1992 and 1995. Fish abundance data wen pooled and classified into three main groups: perch Perca fluviat ilis (L.), roach Rutilus rutilus (L.) and other species. Spearman rank correlations between fish abundance and type of embankment revealed t hat perch showed a statistically significant numerical dominance in wa terways consisting predominately of an artificial shoreline, suggestin g that perch may be used as an indicator of the structural degradation of watercourses.
