Ichthyologists are scientists who specialize in the study of fish. Synonyms for ichthyologists include fish scientists, fish biologists, fish experts, fish researchers, and fishery specialists. These professionals work to understand the behavior, ecology, anatomy, and physiology of fish species. They may focus on a specific aspect of fish biology, such as fish genetics or fish conservation, or they may have a broader understanding of the diverse field of fish science. Regardless of their specialty, ichthyologists play an important role in fish conservation efforts, helping to protect fish populations and ecosystems for future generations.
