Ichthyology
Ichthyology (Greek: ichthy=fish and logos=teaching) is the science of fish, also known as fish science. It is a branch of zoology and deals with fish and their natural and artificial living conditions.
In the meantime, most fish genera have been identified. The behavior and biology of fish, on the other hand, still offers a broad area of research.
The areas of limnology, marine biology and oceanography are closely related to ichthyology.
