ichthyologist

An ichthyologist is a scientist who studies fish, a branch of zoology. The field covers taxonomy, systematics, anatomy, physiology, ecology, behavior, evolution, and conservation of fishes, including marine and freshwater species. Ichthyology intersects with fisheries science, marine biology, and evolutionary biology.

Work includes describing and classifying species, revising taxonomic relationships, and investigating life histories and adaptations. Field research may involve sampling in rivers, lakes, reefs, or deep sea; laboratory work spans anatomy, histology, genetics, and imaging. Modern ichthyology employs molecular techniques, comparative anatomy, paleontology, and computational analyses to infer relationships and distributions. Specimens and data are preserved in natural history collections, which support reference identifications and comparative research.

Education and career: Most ichthyologists hold degrees in biology or zoology, with advanced degrees in the field. They are employed by universities, natural history museums, government agencies, aquariums, conservation organizations, and research institutes. Activities include field surveys, taxonomic work, conservation assessments, and policy advising. Professional standards emphasize ethical collection and animal welfare.

History and organizations: Ichthyology has roots in early natural history and developed as a formal science in the 18th and 19th centuries, with descriptions of many fish species by naturalists. Professional societies such as the American Society of Ichthyologists and Herpetologists support research and publication, and journals like Journal of Fish Biology and Copeia disseminate findings.
