Weight-length relationships were used as a simple method to test differences in condition between several populations of Mediterranean barbel and to examine possible correlations between fish condition and ecological factors. We analysed 14 populations of Mediterranean barbel from two basins with different ecological conditions. Statistical analysis (ANCOVA) showed that there were significant differences (P<0.05) in condition between populations, which could imply differences in habitat characteristics. Oxygen availability and riparian cover seem to be the main ecological factors affecting the condition of this species in the area studied. Therefore, the condition of the Mediterranean barbel may be a good indicator of habitat quality in stream ecosystems.
