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.
FISH stands for fluorescent in situ hybridization. FISH testing, or FISH analysis as it is sometimes referred to, is a relatively new cytogenetic technique that allows a cytogeneticist to determine how many copies of a particular chromosome are present without having to go through all of the steps involved in producing a karyotype.
