CATDOLL : CATDOLL: What kind of fish is the white loach?

1. What kind of species is the white loach?

Freshwater fish.

White loach is a common freshwater fish belonging to the family Loachidae. They usually live in freshwater rivers, lakes, ponds and other environments. They are carnivorous bottom-dwelling fish. Although their body color is usually brown or gray, sometimes white loach will appear, which may be due to genetic mutation or other factors.

Loach can not only breathe with its gills and skin, it also has a special intestinal breathing function. When the weather is hot and humus at the bottom of the pond is rotting and causing severe hypoxia, loach can also jump out of the water or rise vertically to the water surface and swallow air directly with its mouth.

2. There is a white fish that looks like a loach, but it is not a loach. What is its name? It looks very disgusting!

Loach

Spiny eel. Common name: steel loach, knife loach, stone cone. English name: Spiny eel. The body is slender, slightly flattened at the front end, and flat and thin behind the anus. The head is long and pointed. The snout is slightly long, but not as long as the head behind the eyes. The tip of the snout extends forward to form a snout protrusion, and its length is approximately equal to the diameter of the eye. The anterior nostrils are tubular and located on both sides of the snout; the posterior nostrils are round and close to the front edge of the eye. The eyes are located on the upper side of the head, covered with thin skin on the surface, and there is a small inverted spine in front of the eyes, buried in the skin. The mouth is inferior, the mouth cleft is almost triangular, and the corner of the mouth reaches the front edge of the eye or slightly exceeds it. The upper and lower jaws have velvety teeth arranged in a band. The pectoral fins are small and round, there are no pelvic fins, and the dorsal fin and anal fin are connected to the caudal fin respectively. There is a row of independent hard spines in front of the dorsal fin, about 31-33; the anal fin has 3 spines; the caudal fin is slightly pointed. The body scales are small and the lateral line is not obvious. The back of the body is yellowish brown and the abdomen is light yellow. There are two light-colored lines on the head from the eye to the back, extending along the back of the body to the base of the tail fin. There are many reticular patterns on the back and ventral sides of the body, and the reticular patterns at the base of the dorsal fin, anal fin and tail fin are more obvious. There are more than 30 brown vertical stripes on the side of the body. The upper end of the stripes of some individuals is darker black, and some individuals have short spots between the stripes near the ventral side. The base of the dorsal spines is dark brown, the pectoral fins are light yellow or grayish yellow, and the other fins are gray. The lower edge of the anal fin is often decorated with white edges. It is a benthic fish. It lives in shallow waters with many aquatic plants. It feeds on aquatic insects and other small fish. The reproductive period is about July. It is distributed in various water systems in the eastern part of the country. Individuals are not large, generally less than 25 cm in length, but they are widely distributed. This fish is produced in the Yangtze River, the Yellow River and its affiliated lakes and swamps, and has certain economic value. Large spiny eel (Mastacembelus armatus) belongs to the order Perciformes, the suborder Acanthocephali, the family Acanthocephali, and the genus Acanthocephali. Commonly known as: Naconi, Shiconi, Coarse hemp cut, pepper fish, and knife fish. English name: Large spiny eel. The body is slender, slightly flattened in the front, and the tail is flat and thin. The head is long and pointed, with a long and pointed snout at the front. The mouth is inferior, the mouth cleft is shallow, almost triangular, and the corner of the mouth ends below the posterior nostril. Both the upper and lower jaws have velvety tooth bands; the eyes are located in the front of the head and are covered by a membrane. There is a small spine with a backward tip in front of the eye, buried in the skin. The rear edge of the preoperculum generally has three short spines. The body scales are very fine, and the lateral line is complete. The dorsal fin has a long base, and the front part is composed of about 35 free short spines; the anal fin has two spines, and the third fin spine is often buried under the skin; the fin rays of the dorsal and anal fins are opposite, the bases are extremely long, and they are connected to the caudal fin. The pectoral fins are short and round, there are no pelvic fins, and the caudal fin is oblong. The dorsal side of the body is gray-brown or dark brown, and the abdomen is gray-yellow; there is often a black longitudinal band in the middle of the dorsal head; there is also a black longitudinal band on the side of the head from the tip of the snout through the eyes to the top of the gill cover, which often breaks into a longitudinal black spot backwards, extending along the base of the dorsal fin to the base of the caudal fin; there are light spots on the side of the body, thus showing black reticulated or wavy longitudinal stripes; the markings of large individuals are unclear. The pectoral fins are yellow-white, and the other fins are gray-black with light spots, and the fin margins have a gray-white edge. It lives in rivers and streams with gravel bottoms, often hiding in cracks or caves, and feeds on small invertebrates and some plants. It is distributed in various water systems south of the Yangtze River. It is widely distributed in the south. The weight can reach 0.5 kg, the meat is tender and delicious, and it is loved by the public.

3. How long can loaches survive in tap water? What color are wild loaches?

Generally speaking, loaches can survive for about 15 days if they are raised in tap water. However, due to different breeding conditions and other factors, the survival time needs to be determined according to the actual situation. In order to extend the life of loaches, they need to be raised in chlorine-free tap water. Generally, you only need to dry the tap water for a period of time and add some silt to the water, which is related to the fact that loaches like to move in the bottom mud. You can feed them fish viscera at ordinary times, and adjust the feeding amount reasonably according to the loach's eating habits.

1. How long can loaches survive in tap water?

1. Survival time

Loaches raised in tap water can generally survive for about 15 days, but because of different breeding conditions and other factors, the survival time of loaches depends on the specific situation.

2. Breeding methods

(1) It is generally better to use clean river water to breed loaches. If you need to use tap water, you need to air the tap water for a period of time first, and then use it for loaches after the chlorine in the water disappears. This can usually appropriately prolong the survival time of loaches.

(2) Because loaches like to move in the bottom mud, some silt or soil can be added to the water to ensure that the loaches can grow better.

(3) Snails, silkworm pupae, fish viscera and other foods can be fed to the loach. Generally, the loach should be fed twice a day. The daily feeding amount should be 7-8% of the loach's body weight, and the feeding amount should be adjusted reasonably according to the loach's eating habits.

(4) Although loaches are highly adaptable to the environment, they also need to be regularly replaced with fresh water to prevent the water from being too dirty and affecting their growth.

2. What color are wild loaches?

1. Wild loaches are generally yellow in color, which is close to the color of soil, while farmed loaches are darker in color. They are usually not as active as wild loaches and are larger in size. This is mainly because they do not need to look for food everywhere and lack exercise. In contrast, wild loaches that need to look for food everywhere have strong energy and are smaller in size.

2. Wild loaches mainly eat plankton, aquatic insects, crustaceans, algae and other organisms. Sometimes they also eat humus or mud at the bottom of the water. They usually don’t like to eat artificial feed. Because of this, its taste is better than artificial loach, it tastes delicious and is rich in nutrition.

3. Loaches like to hide during the day and come out at night. They have a strong tolerance to low dissolved oxygen environments. Usually in a water-scarce environment, as long as there is moist soil, they can survive for a long time. Because of its strong adaptability, its distribution range is also very wide.
