Identification method of two common freshwater fish with the highest economic value

Black carp and grass carp:

The external difference between the two is mainly body color. Black herring, also known as mullet and snail green, has a distinct blue-black back and fins. The tip of the head is short, only slightly longer than his own body length. Its meat is tender and delicious, especially its tail, which is fat but not greasy, and is praised by gourmets. Grass carp is also called herring and pomfret. Body color is lighter than herring; It is bluish yellow, and the pectoral fin and ventral fin are slightly grayish yellow. Blunt head, long intestine, about twice the body length.

Silver carp and bighead carp:

The head of bighead carp is obviously much bigger, and the ratio of head length to body length is 1: 3, so it is also called chubby head fish.

Chubby fish are darker in color than silver carp and have irregular yellow and black stripes, so they are also called "silver carp head" and "yellow silver carp head".
