Ichthyology is the branch of zoology devoted to the study of fishes . This includes the bony fishes ( Osteichthyes ), the cartilaginous fishes ( Chondrichthyes ) such as sharks and rays , and the jawless fishes ( Agnatha ). Since there are as many species offish as all other vertebrates put together, and they have been evolving for avery long time, there is a bewildering variety; while most species have probably been found and described, there is much that isstill not known about biology and behavior.

The practice of ichthyology is closely connected with marinebiology , limnology , and oceanography .



The first scientific description of fishes occurs in Aristotle , who mentionsvarious facts about 118 species. Little additional work is known until the 1500s , when Guillaume Rondelet published his DePiscibus Marinum describing 244 species. During the 1600s , explorers found newtypes of fish; GeorgeMarkgraf 's Naturalis Brasilae added another 100 species, and in 1686 the Historia Piscium of John Ray and FrancisWillughby described over 400 species.

The title "father of ichthyology" belongs to Peter Artedi , a student of Linnaeus who identified five orders of "fishes" (including cetaceans ) and divided those into genera. Artedi drowned by accident in an Amsterdam canal in 1735 , and Linnaeus published hismanuscripts posthumously.

During the 18th and 19th century , a steady stream of specimens from all parts of the world deluged museums.

In the 1780s MarcusElieser Bloch published Ichthyologia as a series of volumes of plates, and after he died, his associate Johann Gottlob Schneider published the M. E. Blochii Systemae Ichthyologiae describing 1,519 species.

Georges Cuvier 's Regne animal distribué d’après son organisation of1817-1830 was a key step forward for fish classification, and Cuvier worked with his student Achille Valenciennes to produce the 22-volume Histoire Naturelle des Poissons in the 1830s -though never completed, the work described 4,514 species.

Albert Günther publishedhis Catalogue of the Fishes of the British Museum between 1859 and 1870 , describing over 6,800 species and mentioninganother 1,700.

The greatest ichthyologist around the beginning of the 20th century isgenerally considered to be David Starr Jordan , who wrote 650articles and books on the subject, in addition to serving as president of Indiana University and StanfordUniversity .
