Xiaobian has recently also been pursuing the catfish (páng pí), commonly known as cow dung crucian carp, red crucian carp, commonly known as colored pieces in the northwest region, sichuan here some places called dustpan fish, bench fish, cutting board fish. The body length is 5-8 cm, and the lifespan is 3-4 years. The eyes have a colored luster, the back is pale green, with a slight blue shimmer, and the ventral surface is silvery white. The males during the breeding season are brilliant in color. Living in freshwater, omnivorous, eating aquatic plants as well as aquatic organisms, eggs are laid in live river mussels.
Friends living in the countryside know that when they were young, they could often catch such fish in the small river, but at that time, the living conditions were limited, and some of them took home to feed chickens, ducks, geese, or grabbed a few bottles, but because of lack of oxygen, they died after a while, and at that time they were still curious, how could they die? Later, I learned that the original was a lack of oxygen, so the original ornamental fish such as the salmon have high oxygen requirements, and they will die without a little oxygen.
Distribution area
It grows throughout Eurasia and is mainly distributed in Asia in China, Korea, Korea, Japan, Vietnam, Myanmar, Laos and other places. According to the "Chinese Fauna Cyprinidae Middle Volume", there are about 20 species in 5 genera in China, most of which are widely spread species.
The suitable water temperature is 14 - 28 ° C, and the water quality is not picky. This fish has a mild temperament, often swims in groups to feed, and prefers clean tanks with aquatic plants.
The breeding of the catfish is more interesting, the catfish and the river mussel can be called the beloved relatives and friends, and the two sides are the adoptive mothers of their offspring. During the spawning season, they are often accompanied by male and female, looking for habitats in the water for river mussels. Once the river mussel is found, the female sticks out the spawning tube and inserts it into the river mussel's water hole, laying the eggs in the coat cavity of the river mussel. Subsequently, the male also ejaculates near the water hole of the mussel, causing the sperm to flow into the mantle cavity with the water to fertilize the egg. The fertilized eggs attach to the mussel gills for development. Due to the constant absorption of water by the river mussels, the supply of sufficient oxygen, and the protection of the shells, the fertilized eggs of the eels grow and develop carefree inside the mussel shells until they hatch into juveniles.
While adopting the offspring of the catfish, the river mussel also entrusted its own children to the catfish to raise. When the eel swims past the side of the river mussel, because the vibration of the water stimulates the mussel, it discharges a large number of hook larvae from the water hole and attaches the hook to the gills or fins of the fish body. Stimulated by hook larvae, the fish body quickly forms a quilt and wraps the larvae. The larvae parasitize the mantle epithelium in the fish to suck nutrients from the fish. After 2 to 5 weeks, juvenile mussels are formed, broken out of the fish body, and sink into the bottom of the water to live.
Some of the colorful small bream fished in the lake are the same, that is, the sturgeon, but the sturgeon is eaten by the koi, then there is no way, some colors on the trout are more beautiful and beautiful than the koi, and the black dots on the dorsal fin are generally the mother of the trout. Male trout have some red on their dorsal fins, male trout are more vivid in color, attracting female mating, and some have whiskers. There are many colors, there are sold on the Internet, you can also go to fish ponds, lakes and rivers, all kinds of water fishing, some artificial lakes have.
Well, today's Xiaobian will talk about this
