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 16·1 cm fork length and 56·3 g mass. The condition factor of attacked P. duriense was 16% lower than that of unattacked conspecifics.
