Editor's note:
Wild boar is going down the mountain! "Monkey Paper" has arrived at my balcony! News of wildlife entering the city frequently appeared on social media. In fact, we live around us with many native wild animals, who are neighbors, but we rarely know them. Only by understanding, being friendly and accompanying can all things be harmonious and cultivated to achieve success. Xinhua Daily·Jianghuidian, in conjunction with Jiangsu Wildlife Protection Station, Jiangsu Forestry Science Research Institute, Nanjing Institute of Fisheries Science, Nanjing Hongshan Forest Zoo, , etc., launched the "Eye of the Secret Realm·Friends of Humanity" calendar column, which will take you to pay attention to both familiar and mysterious "animal neighbors" through the perspectives of infrared camera , animal observers, etc. Biodiversity is the basis and vitality of human homes. Every solar term day, we will also invite solar term officials to conduct special recommendations and broadcasts on that day. Today, let’s get to know loach together. Among the
Loach family , the most widely distributed
Loach family is a loach family of the genus Loach family and the genus Loach family. They have long bodies, cylindrical shapes, flat and thin tails, small heads and pointed mouths.
Their scales are very small and deep in the skin. The upper part of their bodies is gray-brown, the lower part is white, there are irregular black spots on the sides of their bodies, and spots on the dorsal and caudal fins.
Among the more than 100 species of fish in the family Loach family, loach is the most widely distributed fish, widely distributed in China, Japan, North Korea, Russia and India along the Asian coast. Why is
so adaptable?
loaches have extremely strong adaptability. In addition to breathing with their gills, they can also breathe intestinal , so they have strong tolerance for low dissolved oxygen. In a water-deficient environment, the loach can survive for a long time as long as the soil remains moist.
Loaches have been active in the bottom silt of water for a long time, and they like to lie down during the day and come out at night. The dark environment deteriorates their vision. However, their tentacles, side lines, etc. are very sensitive and play an important role in avoiding enemies and foraging activities.
The breeding season for loaches is April to September, and June to July is the peak breeding season. Loaches are fish that lay eggs many times a year. During the egg spawning activities, they are brave and often go to the water to chase them. The eggs of loaches are sticky. After the eggs are fertilized in water, they will be stuck on aquatic plants or debris in water and hatch. The fertilized eggs that fall to the bottom of the water can also hatch loaches.
The "ginseng" in water is rich in nutrients
Loach meat is fine and tough, with high nutritional value, and is known as the "ginseng" in water. Loach meat is rich in protein , and also contains an unsaturated fatty acid, which can protect blood vessels and is beneficial to the elderly and cardiovascular patients. Loach contains some vitamins higher than other fish, such as vitamins A, C and B vitamins. Regular consumption can improve the body's immunity. In traditional Chinese medicine, loach is also a medicinal herb, which has the effects of nourishing the middle and nourishing qi, nourishing the kidneys and warming the spleen, and removing dampness and reducing yellowing.
