Carp, Koi, Goldfish will show you around the world, local, every moment 🐠🐟 Did you know that The term carp (pl.: carp) is a generic common name for numerous species of freshwater fish from the family Cyprinidae, a very large clade of ray-finned fish mostly native to Eurasia. While carp are prized quarries and are valued (even commercially cultivated) as both food and ornamental fish in many parts of the Old World,[1] they are generally considered useless trash fish and invasive pests in many parts of Africa, Australia and most of the United States.
