Approximately 6% of the freshwater living northern straight-mouth nase Pseudochondrostoma duriense in two Spanish rivers had attached post-metamorphic sea lamprey Petromyzon marinus. Minimum prey size was 16 center dot 1cm fork length and 56 center dot 3g mass. The condition factor of attacked P. duriense was 16% lower than that of unattacked conspecifics.
