A unique heart beat datalogging device was either surgically implanted into the peritoneal cavity (internal-fish) or attached by nylon anchor tags to the dorsal fin rays (external-fish) of the black cod Paranotothenia angustata. Both groups had a mean ± s.e. heart rate of c. 46 beats min−1 after 24 h, and by 20 days external-fish showed a significant reduction (34 ± 3 beats min−1) whereas internal-fish did not (44 ± 2 beats min−1). In demersal fishes external attachment of an electronic recording device may be preferable to surgical implantation.
