What does ichthyology mean?
Ichthyology is the branch of zoology devoted to fish and other aquatic vertebrates. It encompasses the study of their anatomy, physiology, evolution, behavior, habitats, distribution, and relationships with the wider environment. The discipline is important in biology and ecology, but it also has practical applications in fisheries management, aquaculture, conservation, and the identification of species. Modern ichthyologists may combine underwater observation with laboratory research, genetic analysis, and the examination of museum specimens. The word comes from the Greek ikhthys, meaning “fish,” combined with the suffix -logy, meaning “study of.” Although the term is sometimes used informally to refer to keeping or collecting fish, its established meaning is the academic study of fishes.
