Are Monopterus Albus and Loach viviparous or oviparous? Do they belong to fish?

In rural rice fields, more and more farmers are trying to raise two kinds of bare animals, ricefield eel and Loach. So do they belong to fish? Is it viviparity or egg birth? According to Peng Zi, a farmer of Monopterus Albus in Ningxiang, Hunan Province, the fish swims with fins and breathes through its gills all its life. It is a vertebrate that lives in the water all its life. Monopterus Albus meets this condition and belongs to fish. Eel is a common name of people, and Loach is also called Loach, known as "ginseng in the water", living in the lake pond, is a kind of fish with high nutritional value, it is different from other fish, regardless of appearance, body shape, living habits are different, is a special fish. In addition, both belong to fish, so they are both egg-laying animals.

Yellow eel is a benthic fish living in fresh water, which requires a relatively stable living environment and likes to live in places with dark light, small water temperature difference and less human disturbance. Like to live in soft and humus shallow water and still water silt, about 30 cm from the ground camp life. Eels like to live in holes and directly drill holes without draining the soil out. There are two or more holes in the cave, and another one for breeding is called breeding hole, which is wider and more hidden. The burrowing property of eel varies with the change of temperature and water level, and the burrowing property of eel is also different in different regions and different specifications.

No matter which culture method is adopted, such as cage, courtyard, factory culture and soilless or soilless culture, the culture water level should be shallow, and fish nests or aquatic plants should be set up. It is found that although eels eat more without nests, they have more exercise and energy consumption, and vice versa, so it is best to adopt semi-shaded healthy culture, so that eels eat more and consume less so as to gain weight quickly and improve the efficiency of culture.

Eels like to eat fresh bait, not unpalatable or rotten food, most like to eat small fish, shrimp, aquatic insects and other larvae, followed by terrestrial insects and earthworms, if the mussel, snail shell also like to eat.

The feeding mode of eel is the sobbing type, which is rare in fish, and it can quickly attack and devour its prey within an effective range. If a certain kind of bait has been fed for a long time, it is also difficult to change its eating habits, so wild eels should be domesticated in a short time. According to this characteristic, a kind of artificial formula feed with long-term feeding, low cost and high meat gain rate should be selected. Where there are conditions, lights can be set up in the pond to lure insects into the pond for eels to eat.

The Loach is a small demersal fish. Living in the static or slow running water at the bottom of the silt, it has strong adaptability and can live in an environment rich in humus. When the water is anoxic, intestinal breathing can be carried out, and after the water body dries up, it can be drilled into the mud to lurk. Send all kinds of small animals for food. For batch spawning, the main breeding period is from May to June. Fertilized eggs are attached to aquatic plants and hatched. The largest individual can be up to 300 mm long, with good meat quality, which is one of the exported aquatic products.

Misgurnus anguillicaudatus likes to inhabit the bottom of still water and is often found in lakes, ponds, ditches and silt surfaces rich in plant debris at the bottom of paddy fields. The living water temperature is 10-30 ℃, and the optimum water temperature is 25-27 ℃, so it should be a warm-water fish. When the water temperature rises to 30 ℃, Loach will dive into the mud to spend the summer. When the water temperature drops below 5 ℃ in winter, it will drill into the 20~30cm deep in the mud to survive the winter.
