Establishment of a multi-parametric ichthyological index for the assessment of the ecological status of upland streams and rivers.
Study Area: Segments of the rivers Alfios, Arachthos, Acheloos, Aliakmon and Aoos.
Project aims include the development of methodology for the assessment of the ecological status of upland rivers using fish as the tool for the assessment procedure. The following methodological steps will be followed:
(a) Collection of data on human pressures in the study areas
(b) Establishment of a biotic typology
(c) Biological sampling in a number of stations
(d) Selection of appropriate metrics
(e) Assessment of reference conditions
(f) Establishment of the metric scale that estimates deviation from the reference conditions
(g) Development of a multimetric index for the assessment of ecological status of rivers.
