Why do loaches like to get stuck in the cracks of the stones?

1. Is a loach a fish?

Loaches are fish. Fish breathe with gills, live mainly in water, and swim mainly by fins on the body, these characteristics are reflected in it, so it is undoubtedly a fish. Taxonomically, it belongs to the class Bony Fishes.

It is an animal of the genus Loach of the Cypriniformes family, and other fish of the same order include silver carp.

Grass carp, etc., they can be regarded as relatives among themselves.

2. Why do loaches like to drill mud?

Loaches burrowing into the mud are usually due to the unsuitable environment of the water body. Its living water temperature is between 10-30, and if the water temperature exceeds 30, it will burrow into the mud for the summer. If the water temperature is below 5, it will also burrow into the mud for the winter.

In addition, when the water body dries up, it can also burrow into the mud to continue to survive without dying due to lack of water. The reason why it can survive in the mud is that in addition to breathing with gills and **, it can also breathe through the intestines, while also relying on a small amount of water in the soil to avoid **dryness.

3. The living habits of loaches.

Loaches are small demersal fish, it has strong adaptability, tolerance for low dissolved oxygen environment is also relatively high, can survive for a long time after leaving the water, juvenile fish can live for 1 hour, adult fish can live for about 6 hours, and during the period back into the water can still move normally. It usually comes out at night to hunt and its diet consists mainly of plankton.

Aquatic insects, crustaceans.

and aquatic plants.

debris, etc.

Loaches prefer to inhabit the bottom of still water, and are often found at the bottom of lakes, ponds, ditches and paddy fields, as well as in stone crevices, where they are rich in plant detritus and are adaptable to the environment.

Whenever there is a drought, the loache burrows into the mud so that it can survive when other fish are dying due to lack of water. In winter, it burrows deep into the mud to fight the cold.

3.It turns out that this is because the loach has a special way of breathing, in addition to absorbing oxygen in the water with its gills like other fish, it can also get oxygen directly from the air through the intestines and **.

Loaches have spines. Compared with common fish, loaches have smaller spines and are mostly in the body, and some loaches also have spines on their dorsal fins, which have an important supporting role. Loaches are bottom-dwelling fish that inhabit the bottom of various shallow and silty environmental waters such as rivers, lakes, ditches, paddy fields, ponds and marshes.

Diurnal and nocturnal, it is adaptable and can live in humus-rich environments. When there is a lack of oxygen in the water, it can jump to the surface of the water and swallow air for intestinal respiration. When the pool dries up, dive into the mud and survive as long as the soil is moistened with a small amount of water.

Loach: The upper part of the loach is grayish-brown, the lower part is white, and there are irregular black spots on the side of the body. There are also spots on the dorsal and caudal fins.

There is a large black spot above the base of the caudal fin. The other fins are grayish-white. Loaches eat almost everything, in addition to feeding on small crustaceans, insect larvae, earthworms, but also on higher aquatic plants, algae and organic detritus, etc., and then gradually become omnivorous fish, all animals and plants in the water and mud and organic detritus, are the natural bait of loaches.

Loaches have no spines.

The loach has no undereye spines, no dorsal fins, 3 unbranched fins, and 8 branched fins, a total of 11. The dorsal fin is opposite the pelvic fin, but begins before the pelvic fin, about the posterior margin of the anterior operculum and the midpoint of the base of the caudal fin. The pectoral fin is far from the pelvic fin, the pelvic fin is short, the origin is located in the middle and posterior of the dorsal fin base, and the pelvic fin does not reach the anal fin.

The caudal fin is rounded.

Loaches have spines, but they are relatively rare. The body of this fish is extremely slender, the sides of the body are flattened or slightly cylindrical and long, the body color is mottled golden-brown with black spots, and 1 dorsal fin, about the same size as the back; anal fin short; Located behind the dorsal fin, the posterior margin of the caudal fin is rounded, with a spot above the end of the caudal peduncle, 9 dorsal fin soft stripes, and 7 anal fins. It has 10 tentacles and can reach a length of 28 cm.

The fish inhabits rivers, lakes, ponds and paddy fields, has a mild, omnivorous temperament, feeds on worms, small crustaceans, insects, etc., tolerates temperatures between 2 and 30, and can breathe air directly on the surface of the water when oxygen is insufficient. When the air pressure is low, it becomes very active.

Loaches have spines, but the spines are small.

Loach (Misgurnus anguillicaudatus) belongs to the family Loachidae. Loaches are called"Ginseng in the water"It is found all over southern China, and it is not common in the north, but it is also distributed everywhere. It can be harvested all year round, most often in summer, and after the loaches are caught, they can be used fresh or dried.

Loaches live in lakes and ponds, and are small in size, only.

Three or four inches long. It is round, short, with small scales under its skin, blue and black, and covered in its own mucus, making it too slippery to hold. It is a kind of fish with high nutritional value, it is different from other fish, no matter the appearance, body shape, life habits are different, it is a special loach.

The body is elongated, and the anterior segment is slightly cylindrical. Posterior lateral flattening, abdomen rounded, head small, mouth small, lower, horseshoe-shaped. The eyes are small and there are no under-eye stingers.

5 pairs are required. The scales are extremely small, rounded, and buried under the skin. The dorsal and flanks of the body are grayish-black, with many small black spots on the whole, many black spots on the head and various fins, the spots on the dorsal fin and caudal fin membrane are arranged in rows, and there is a distinct black spot at the base of the caudal peduncle.

The other fins are grayish-white.

Loach is a common aquatic food, with delicate meat, delicious taste and rich nutrition, and is known as ginseng in water. The edible part of the loach accounts for about 80% of the whole fish body, which is higher than that of ordinary freshwater fish. Loach contains high-quality protein, fat, vitamins, niacin, iron, phosphorus, calcium, etc., which has the effect of tonifying and benefiting qi, clearing urine, detoxifying and collecting hemorrhoids, nourishing the kidneys and producing sperm, especially suitable for people with weak body, spleen and stomach deficiency and cold, malnutrition, and night sweats.

In particular, it contains an unsaturated fatty acid similar to docosapentenic acid, which is beneficial to the body's anti-aging. Loach is rich in nucleosides, which are the main components of various vaccines, which can improve the body's antiviral ability, especially suitable for people with acute and chronic hepatitis and jaundice, and can promote the decline of jaundice and aminotransferases.

Loaches are fish that have no spines.

Of course not. I've been catching loaches in the river since I was a kid.

I didn't feel it when I ate it. It's like only one backbone.

Summary. Loaches lie on their stomachs at the bottom of rivers in search of food or to hide from predators.

Excuse me, but please go into more detail?

Loach is a small freshwater fish that lives in waters such as ditches, rivers, lakes, etc. Loaches usually lie on the bottom of rivers because they are benthic fish that lie on the bottom of rivers to avoid predators and find food. Loaches are soft and adaptable to the river bottom, and their senses of smell, touch and hearing are able to find food, which makes them easy to survive at the bottom of the river.

In addition, loaches are able to absorb oxygen by breathing** and can also avoid wind and waves by burrowing into the mud at the bottom of the river, which are essential survival strategies for loaches lying on the bottom of the river.

Summary. In response to the problem, the loach fish lie on the bottom of the river to hunt, they will lurk at the bottom of the river, wait for their prey to swim by, and then pounce on it to hunt. Workaround and Procedure Steps:

1.First of all, to control the number of loach, you can take the way of fishing, and catch the loach at the bottom of the river to reduce the occupation of the river bottom by the loach. 2.

Secondly, to improve the water quality of the river bottom, you can take the river bottom cleaning method to clean up the pollutants at the river bottom, so as to improve the water quality of the river bottom, so that the loach no longer lie on the bottom of the river. 3.Finally, to improve the ecological environment at the bottom of the river, you can take the way of plant planting and plant some aquatic plants at the bottom of the river to improve the ecological environment at the bottom of the river, so that the loach no longer lies on the bottom of the river.

In short, if you want to make loach no longer lie on the bottom of the river, you must control the number of loach, improve the water quality of the river bottom, and improve the ecological environment of the river bottom, so that the loach no longer lie on the bottom of the river.

In short, if you want to make loach no longer lie on the bottom of the river, you must control the number of loach sold and excavated, improve the water quality at the bottom of the river, and improve the ecological environment at the bottom of the river, so that the loach no longer lie on the bottom of the river.

You've done a great job! Can you elaborate on that?

Loach fish are freshwater fish that like to move in the sediment at the bottom of the river, so they lie on the bottom of the river to hunt. Loach fish hunt by lying in ambush in the mud and sand at the bottom of the river, waiting for their prey to swim by, and then swooping over to catch their prey. The predation objects of loach fish are mainly small aquatic animals, such as earthworms, tadpoles, small shrimps, etc.

Predation by loach fish can also help clean up pollutants from the river bottom, as they eat the harmful substances at the river bottom, thus reducing pollution. In addition, loach can also help control the population of certain pests in the water body, thereby protecting the ecological environment of the water body. The predation of loach fish also helps to improve the water quality of the water body, as they eat the harmful substances in the water body, thus reducing the pollution of the water body.

In addition, loach can also help control the population of certain pests in the water body, thereby protecting the ecological environment of the water body. In short, loach lying on the bottom of the river is catching and eating, and their predatory behavior can not only help clean up the pollutants at the bottom of the river, but also improve the water quality and protect the ecological environment of the water body.

<> loach has spines, but compared with common fish, the spines are relatively small, loaches are one of the most common aquatic products in our bucket Wangna, its meat is delicate, delicious, rich in nutritional value, has the reputation of ginseng in the water, its edible part accounts for 80% of the whole fish body, higher than most freshwater fish.
