CATDOLL : CATDOLL: Should loach and water fry be fed on rainy days?

1. Do loach and water flower seedlings need to be fed on rainy days?

Definitely necessary, reduce the food intake, too much food will affect the water quality

2. How do fish breathe?

Most fish rely on oxygen dissolved in water to complete their respiration, and the main respiratory organ here is the gill. However, some fish can use oxygen in the air to breathe, which is called pneumatic respiration. Fish that can pneumatically breathe mostly live in tropical or subtropical areas or waters where dissolved oxygen is often lacking, or have a special lifestyle. It is the result of fish adapting to the environment. Fish have many pneumatic respiration organs, which are briefly introduced below.

1. Skin: The skin of these fish is bare or has very small scales, which are covered with microvessels, and can exchange gases and complete respiration. Such as eels, rice field eels, loaches, mudskippers, etc. Based on this, eels can crawl onto the shore at night, pass through wet grass, and migrate to other water bodies.

2. Oropharyngeal cavity: The eel lives in rice fields or shallow ditches with low dissolved oxygen, and is good at digging holes in the soil to live. Its gills are degenerate, but the inner wall of the oropharyngeal cavity is rich in capillaries. It always sticks its head out of the water from time to time to swallow air and expel waste gas. Therefore, as long as anglers observe patiently in the waters where the eel lives, it is easy to find the target. Other fish that can use the oropharyngeal cavity to breathe air include electric eels and other fish of the genus Synbranch.

3. Digestive tract: Catfish and catfish native to South America can use their stomachs to breathe. However, loaches, flower loaches and other fish of the family Cobitidae, which are widely distributed in my country, can use their intestines to breathe. They often float to the surface of the water to swallow air, and the air passes through the intestines and is discharged from the anus to complete the breathing. Therefore, the so-called loach "farts" are actually loach breathing.

4. Suprabranchial organs: These fish have developed specialized air breathing organs in the gill cavity or above the gills, namely, suprabranchial organs. There are many such fish, most of which live in tropical or subtropical areas. Common ones include fighting fish, catfish, climbing perch, silk-foot fish, and snakehead.

5. Air sac: The only fish that breathes with air sacs is the Indian sacbranch. It has a pair of long tubular sacs that extend from the gill cavity backward through the muscles near the spine to the tail. The inner wall of the sacs is rich in blood vessels. When alive, the sacs are filled with air, allowing it to survive on land for quite a while.

6. Swim bladder: The swim bladders of many ancient fish can be used for air breathing, such as lungfish, bifin fish, bowfin fish, gar, etc. Their swim bladders have tubes connected to the esophagus. In an oxygen-deficient environment, these fish swallow air into their swim bladders for air breathing.

Most fish use air respiration as an auxiliary means of gill respiration, that is, in an environment lacking dissolved oxygen, when gill respiration cannot meet the oxygen needs of the fish body, air respiration is used as a supplementary source. For example, loach rarely breathes in water rich in dissolved oxygen, but when there is a lack of oxygen in the water, it frequently floats up to swallow air. However, for some fish, air respiration has become the main source of oxygen required by the body, and gill respiration is not as good as air respiration. If these fish are pressed in deep water for a long time, they will "drowned" to death, such as eels, African lungfish, American lungfish, etc. Especially African lungfish, in the season when the pond water is dry, it can use mud and mucus to create a special "cocoon" shell at the bottom of the pond. There are small holes on the top of the "cocoon" shell that communicate with the outside air. At this time, the lungfish hides in the "cocoon" shell, does not eat or move, and relies entirely on the swim bladder to breathe air to survive the dry period of several months. When the rainy season comes, it breaks out of the shell and continues to eat and grow.

3. Is it better to have a big loach or a small one?

The question you asked,

Now there is a kind of loach that is very big.

But the color is flowery,

The price is less than 20 yuan.

The other type has a white belly.

The price is above 30.

If you want to buy, buy this kind.

The meat is delicious, soft and tender.

Be sure to look carefully when buying.

4. What kind of flower is this? (with photos)

Red flower peach ~ just ready to plant ~

5. Is loach a amphibious animal?

Loach is not an amphibian, but a fish, belonging to the order Cypriniformes, family Cobitidae, subfamily Cynomorinae, genus Loach.

6. What kind of flower is this? The flowers in the roadside flowerbeds are in pots and pots. They are purple and have pointed leaves.

SageEdit

[1] Salvia japanica, also known as medicinal sage, Salvia[1], and Ishimizu, is an aromatic plant of the genus Salvia in the family Lamiaceae. It is an evergreen small subshrub with woody stems, gray-green leaves, and blue to blue-purple flowers. It is native to southern Europe and the Mediterranean coast.

Sage has many different uses and benefits, and some of its genus plants have the same benefits. It is often cultivated as a kitchen herb or medicinal herb, and is sometimes called garden sage, kitchen sage, or Dalmatian sage. In southern Europe, some plants similar to sage are sometimes grown as herbs and medicinal herbs, and these plants of the same genus are often confused with true sage.
