Hint: Fishes refer to the members of the superclass Pisces. The members of Pisces are exclusively aquatic. They belong to the phylum Chordata or Vertebrata. They are further classified into the group Gnathostomata that consists of the members having jaws.

Complete answer:The fishes belong to the phylum Chordata because they have a persistent notochord that develops into the vertebral column. Fishes are characterized by the presence of the scales on their skin or the tegument. They also have several kinds of fins.
Exotic fishes refer to the fishes that are not native to any area and are brought from a foreign place. They are usually imported from countries outside of India. The exotic species are usually introduced for various economic purposes. The yield of exotic fishes is better. Moreover, they taste very good and are a delicacy. Also, various fish products are used to make several items. Therefore, for better-culturing prospects and income, several fish rearers culture the exotic or the foreign species of the fishes.
The rearing and the culturing of the fishes for economic purposes are known as Pisciculture. The three important exotic fishes that are being cultured in India for economic purposes are:
1. Common carp which is also known as the European carp is exported from various parts of Europe and Asia.
2. Grass carp are found in eastern Asia.
3. Silver carp found in China and eastern Siberia.

Note:The fishes that are found in any area and are native to that area only are known as the Indigenous species or the Indigenous fishes of that area. Some of the indigenous species of the fishes of India are Labeo rohita (Rohu) found in the rivers of the Indian subcontinent; Catla catla (Catla) found in the rivers and the lakes of India; Clarias batrachus (Magur) found in Southeast Asia and the Indian rivers; Hilsa found in the brackish waters and the freshwaters of West Bengal, Tripura, Assam, Odisha, and Andhra Pradesh; Mrigal carp found in the Cauvery river, etc.
