Information
Ecological parameter: fish region (fiBS)
Parameter group: region related parameters
Explanation:
With the help of the fish region index concept developed in Austria by Schmutz et al. (2000), fish species occurring in running waters are characterised regarding their natural preferences for the different stream zonation regions from the epirhithral to the hypopotamal (Illies, 1961).
