Stomach contents from 401 individuals representing six species of echeneids were examined. Parasitic copepods are an important part of the diet of echeneid fishes. Parasitic copepods were present in 70% of the stomachs of Remora remora containing food and in four other species to a lesser, but significant extent. The growth stage of the life history of the echeneid during which it feeds on parasites varies among species. In R. remora the younger individuals are more active as parasite pickers whereas in R. osteochir older specimens are more active. Life history information resulting from extensive collection data is included in the discussion of each of the six species considered.
Copeia is an internationally respected, widely-cited quarterly that publishes original research on fishes, amphibians and reptiles, emphasizing systematics, ecology, conservation, behavior, genetics, morphology and physiology.
The American Society of Ichthyologists and Herpetologists is dedicated to the scientific study of fishes, amphibians, and reptiles. The primary emphases of the Society are to increase knowledge about these organisms, to disseminate that knowledge through publications, conferences, symposia, and other means, and to encourage and support young scientists who will make future advances in these fields. The programs of the American Society of Ichthyologists and Herpetologists are part of a global effort to interpret, understand, and conserve the Earth's natural diversity and to contribute to the wise use of natural resources for the long-term benefit of humankind.
