Morphological characteristics of the inverse fish The body is medium-long and flattened laterally. Slightly bulging of the dorsal abdomen. The head is small. The eyes are large and lateral. The length of the kiss is equal to the diameter of the eye. The mouth is nearly lower, and the mouth is curved. The dorsal fin end root is a hard spine that is equal to or slightly greater than the length of the head. The dorsal fin starts near or equal to the base of the tail. The pectoral fin does not reach the ventral fin. The ventral fin starts opposite or later from the dorsal fin start. The abdomen is rounded in front of the ventral fin and has a pronounced ventral ridge from the base of the pectoral fin to the anus. The anus is close to the fin. The caudal fin is bifurcated. The side lines are complete. The body color is dorsal greyish brown and the abdomen is silvery white. The dorsal fin and caudal fin are light grey, and the ventral fin base is not light yellow.
Chinese scientific name reverse fish
Hanyu Pinyin nìyú
The distribution area is distributed in the Yangtze River system
Omnivorous, plant-based feeding predominantly breeding period May-June Active water rapids in streams and rivers
Suitable fishing temperature 22 °C ~ 28 °C Also known as bream, flat neck, floating silver carp
1. Appearance characteristics
The reverse fish is also called "swing belly", the mouth is small and lower, and it is split; The mandibular margins are underdeveloped. The eye diameter is equal to the length of the kiss. One line of hypopharyngeal teeth. Lateral scales 41 to 50. The ventral ridge is incomplete, with a pronounced ventral ridge from the base of the ventral fin to the anus.
2. Life habits
Common small fish, like to swim against the water in clusters. Algae (diatoms, filamentous cyanobacteria) are the main food, and some individuals also eat some branches, copepods and crustaceans. At 1 year old, it is sexually mature, and eggs are laid from May to June, and the eggs are drifting and spawned in rapids streams. The number of eggs conceived is about 19,000 to 33,000. Individuals are small, reproduce quickly, and have large numbers. It is distributed in the Yangtze River system.
3. Distribution range
This fish is originally distributed in rivers, lakes, ponds and other water bodies in China except for the Qinghai-Tibet Plateau, and has been introduced to freshwater waters around the world.
4. Techniques for catching reverse fish
Semi-water fishing, the drift phase pulled down is the mouth, the drift phase of the swinging belly is chaotic, there is shaking, there is a drift like being blown by the wind, and some drift panning one or two centimeters, there are also drifting at all do not move the fish in the rod, if you look at the basic can not catch up, during the car accident a lot, there are two or three out of ten! The reasons for this may be:
First, the weather is hot, and the desire to eat fish cords is not strong;
Second, semi-water fishing, when the fish eats, it happens to be in the same water layer as the bait, and the floating eye does not float up and down, and there is a slight translation;
Third, it may be that the sub-line is a little longer, and the small action cannot be reflected in the drift (no. 1 jujube core drift).
