Copeia is a broadly based scientific journal of the American Society of Ichthyologists and Herpetologists (ASIH). It publishes results of original research performed by members in which fish, amphibians, or reptiles are utilized as study organisms.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.

In the Middle Ages it found its wayback to Europe and became the chief navigational instrument until theinvention of the sextant in the 18th century.
