A sudden surprise: a rare wild Yangtze shad weighing about one catty. An hour passed, no fish took the bait, and the new position still had no fish mouth. Then I caught a wild silver carp and bighead carp.

The upper and lower jaws have sharp edges, which are separated from the lips. They have two pairs of whiskers, thick kisses, short and small jaws or only three rows of hypopharyngeal teeth, medium size and round scales.

Basic fishing information:

Generally, it is 15 ~ 25 cm long, with flat sides, slightly raised back in front of dorsal fin and round and slightly straight abdomen. The head is short, the kiss is round and blunt, the kiss length is slightly larger than the eye diameter, and the mouth is small and low, showing an arc shape. The edge of the upper lip is wavy, the posterior sulcus of the lip is interrupted, and the edge of the lower lip covers the mastoid process.

38 ~ 42 lateral scales. The dorsal fin has no hard spines, and the distance from the starting point to the base of the tail is greater than the distance to the snout. The pectoral fin is short, the caudal fin is wide and deeply forked, with a bluish white body and a silvery white luster. There are 8 ~ 12 scales above the pectoral fin and the lateral line with black spots at the base, which are piled up into rhombic patches, and there is a black spot at the base of the tail scale of young fish.
