Assessment of fish fauna structure and hydromorphological and physico-chemical status of the river in the aspect of good ecological status
Summary.

This paper presents assessment of ecological status of small lowland river. The evaluation was made on the basis of biological elements such as composition, abundance and age structure of fish fauna additionally hydromorphological and physico-chemical elements support the biological elements. The Struga Dormowska River is located in the Wielkopolska Lowland. Watershed area is 57.2 km2 and the river is 19.9 km long. Assessment of the ecological status reveals moderate influence of human activity on the river. This state, results from the break of the river continuity, is caused by hydrotechnical constructions. The hydromorphological status of the river is good due to the nearly nature hydrological regime and good morphological conditions of the river bed and riparian zone. Low concentration of dissolved oxygen and high concentration of BOD, COD, nitrate nitrogen and ammonium nitrogen caused that physical and chemical status of the river was below good.

Key words: lowland river, ecological status, fish fauna structure, physic-chemical status, hydromorphological status
