Radio tracking of a fin whale /Balaenoptera physalus/Tracking of a fin whale tagged with an implantable beacon transmitter (IBT) is described. The IBT, which was fired from a modified 12-gauge shotgun, weighs 517 g and is 70 cm long, including a 46-cm antenna. Data on whale movement and breathing are presented. Contact was lost after 27.8 hours of intermittent tracking, presumably as a result of battery leakage. Potential range and duration of IBT transmission are considered, and the significance of transmitter location and orientation in the whale blubber is considered.
