<jats:title>Abstract</jats:title><jats:p>We compared baseline and maximal cortisol concentrations between predator exposure and prey blood samples in pumpkinseed <jats:italic>Lepomis gibbosus</jats:italic>, captured using a standardised fishing event underneath osprey <jats:italic>Pandion haliaetus</jats:italic> nests and away from osprey nests. We did not detect differences in cortisol or glucose between sites. These findings suggest that predictable sources of predation risk may not confer stress‐related costs in teleosts.</jats:p>
