The term 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.

The black carp or Chinese black roach is a species of cyprinid freshwater fish and the sole extant species of the genus Mylopharyngodon. It is native to lakes and rivers in East Asia, ranging from the Amur Basin across China to Vietnam.

The mrigal carp, also known as the white carp, is a species of ray-finned fish in the carp family. Native to streams and rivers in India, the only surviving wild population is in the Cauvery River, leading to its IUCN rating as vulnerable.

Sinotaia quadrata is a species of a freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Viviparidae. It is widely distributed and common species in China and in northern Vietnam inhabiting various shallow freshwater habitats, where it can reach high densities. It is a keystone species in its habitat and can significantly affect water quality and phytoplankton communities. It is commonly used in Chinese cuisine.
