Study Notes
Fish Systematics and Taxonomy: An Overview
- The field of fish systematics is concerned with the study and understanding of the diversification of fishes, both past and present, and the classification of and evolutionary relationships among them.
- Fish systematics is a branch of systematic biology, which is the scientific classification of organisms.
- Taxonomy is a component field of systematics that involves the art and science of describing organisms and the methods of grouping them hierarchically.
- The history of biological classification dates back to ancient times, with Aristotle being the first to classify living things.
- Carl Linnaeus introduced binomial nomenclature in the 18th century, which is still used today in modern taxonomy.
- The total number of fish species described as of February 2022 is approximately 34,800 according to Fishbase.
- The contemporary systematics of fish is primarily based on morphological traits, but discerning finer differences among strains, races, and biotypes can be challenging.
- DNA-based marker systems, such as whole mitochondrial genome sequences, are being increasingly used in fish systematics to determine evolutionary relationships.
- The field of systematics includes various branches such as numerical systematics, biochemical systematics, and experimental systematics.
- Freshwater fishes constitute approximately 25% of all vertebrates and are an important component of global biodiversity.
- There are over 15,000 freshwater fish species, and taxonomic work is ongoing, with an average of 305 new fish species described per year since 1976.
- The predominant fish families in freshwater are Cyprinidae, Gobiidae, Cichlidae, Characidae, Loricariidae, and Balitoridae.
