Because of their exposure in marine parks, movies, and television as well as their presence in tropical and warm-temperature waters around the world, bottlenose dolphins are among the most familiar of marine mammals. Since they are relatively easy to obtain and they thrive in captivity, these dolphins have been used in a great variety of studies. Work with the bottlenose has provided insight into the sensory mechanisms, communication systems, energetics, reproduction, anatomy, and other aspects of cetacean biology. This volume presents the most recent biological and behavioral discoveries of bottlenose dolphins from different regions and compares bottlenose dolphins as a group with other species of animals.

Conventional tags are applied to tunas and billfishes, using several different methods to handle the fish. The importance of making satisfactory arrangements for collecting the tagged fish which are recaptured, and the pertinent data, is discussed. Some suggestions for handling the data are given. Ultrasonic telemetry has been used extensively on tunas and billfishes during the last few years. Fishing techniques, transmitter attachment, hydrophone systems, and data collection and storage are discussed. Some tagging systems which may be used on tunas and billfishes in the future are described.
