There are three distinct groups of fish that ichthyologists study: bony fish, cartilaginous fish, and jawless fish. Ichthyology has a long history that began with simple observations and descriptions of fish over 200 years. The first known recorded observations of fish were documented by Pierre Belon in the 1500âs.
Other fisheries biologists work to assess how many fish are in the ocean, a river, or lake. This requires a lot of field work to observe the fish, usually by capturing and counting them. This information helps the fisheries managers to decide how many fish can be caught.
