2. What are the four major southern fish species?

The four major carps are silver carp, grass carp, bighead carp and black carp.

3. How many species of fish are there?

There are more than 2,000 species of fish.

4. How many kinds of freshwater fish are there?

Among the freshwater fish in my country, some species are widely distributed and can be found almost everywhere. For example, grass carp, bream, triangular bream, red-eyed trout (etc.) feed mainly on aquatic plants; silver carp, bighead carp, etc. feed on plankton; omnivorous carp, crucian carp, etc.; others include flower carp, wheatear fish, Da's snakehead, silver carp, mullet, club flower fish, yellow eel, white eel, flower loach, loach, catfish, as well as common ferocious fish such as black snakehead, mandarin fish, bighead carp, etc.; in addition, there are mild carnivorous fish such as red carp, Mongolian red carp and black carp.

In addition to the above-mentioned widespread species, there are also many common species in local waters. There are about 90 species of fish in the Heilongjiang River and its tributaries in Northeast my country, including about 50 species of carp. Because the Heilongjiang River is located in the temperate and subarctic zones, it produces a lot of cold-water fish. Common species with greater economic significance include Taimen, Smelt, Ussuri Whitefish, Arctic Grayling, Sturgeon, Dabry's Whitefish, Pike and migratory salmon. In addition, there are also endemic species in the north, such as Asian Smelt, Northern Loach, Heilongjiang Duven, and Variegated Duven.

As the geographical location moves southward, there are more and more temperate fish in rivers, while cold-water fish are gradually decreasing. There are about 70 species of fish in the Liaohe River system, and there are also northern species in its upper reaches; there are about 140 species in the Yellow River system and about 300 species in the Yangtze River system. There are very few cold-water fish in the two. In addition to the common important economic fish such as silver carp, grass carp, bighead carp, bream, bream, bream, red-eyed trout, and mullet, there are also endemic species such as shad.

The upper reaches of the Yellow River and the Yangtze River and some rivers in the Northwest Plateau have very special fish species due to the terrain. For example, there are 13 species of schizothorax and 8 species of schizothorax in the Cyprinidae family. Local endemic species include spotted naked carp, Xinjiang double-lip angler, Chinese saw-barbed barb and white armored fish.

The Pearl River system is rich in fish resources, with a total of more than 260 species. In addition to species that are widely distributed throughout the country, there are also some special types of fish, such as the giant mullet and the silver carp, as well as species unique to South China, such as the dace, the silver carp, the four-barbed dace, the straight-mouthed dace, the tang fish, and the South China carp.

The plateau rivers in southwest my country, such as the Yarlung Zangbo River, Nujiang River, Lancang River, and Jinsha River, have fast currents in many sections and average fish resources. For example, the genera of Cyprinidae, such as the genera of Dongpo Cyprinidae and the genera of Dagu, the genera of Cobitidae, such as the genera of Flatfin Loach and Sand Loach, and the genera of Exostomidae are the same as those in India, Myanmar, Vietnam, and Thailand. In addition, the genera of Schizothorax, the genera of Naked Schizothorax, and the genera of Basilisk are the same as those in the northwest plateau.
