Arowana. Chinese scientific name: red striped loach.

Latin scientific name: Mastacembelus erythrotaenia, English name: fire eel (fire eel).

Maximum body length: 100cm

Active area: bottom waters.

Suitable environment: 24 28, PH 6 8, DH 5 19 Origin: Thailand, Cambodia, Indonesia.

Food: benthic insect larvae, worms, and some plant foods.

Some aquarists who have raised it say that it eats fish pieces, small fish, earthworms, bloodworms, shrimp, etc., and may eat it at night. There needs to be a place to hide, such as a stone cave, PVC pipe, etc. Eat a lot, like to eat small fish and river shrimp, pull a lot of poop, easy to pollute the water quality, eat nothing like to hide in the corner, if there is a bottom sand or aquatic weeds, it is a destroyer, like to shuttle in the bottom sand.

It can be polycultured with almost all fish. Is that it?

Freshwater eels often hunt at night and feed on small fish, crabs, shrimp, crustaceans and aquatic insects, as well as rotting carcasses of animals, and some individuals have higher plant detritus found in their food. Feeding intensity and growth rate increased with the increase of water temperature, and were generally the highest in spring and summer.

Pond-reared freshwater eels feed less intensely in midsummer. When the water temperature is lower than 15 or higher than 30, appetite decreases and growth slows down; Stop feeding below 10. Dive into the mud in winter and hibernate.

Freshwater eels can breathe and sometimes leave the water, and as long as they remain moist, they will not die.

If you need to breed freshwater eels, the earthen pond of eel breeding requires ventilation and sunshine, sufficient water source, and the area should not be too large, and plant 1 meter wide water floating lotus or water peanut around the earthen pond, and use a fence or mesh fence, so that the eel can be prevented from escaping, and can be shaded, which is conducive to its growth.

Before stocking, the excessive silt in the land should be dug out, the bottom of the pond should be leveled, the ridge of the pond and the inlet and drainage outlets should be repaired, and the pond should be cleaned and disinfected with 100 kg of quicklime and 125 kg per 1000 square meters every 1000 days before the eel is planted, so as to completely kill wild trash fish and predators.

Then 5 days and 7 days before the eels are planted in the pond, the water is filled with meters to a depth of rice, and the water inlet is filtered with a 60-mesh sieve. Finally, apply base fertilizer, generally every 1000 square meters of 300 kg of decomposed pig manure 400 kg, until the water is light green or yellow-brown and then put eel seeds, so that they can eat sufficient natural bait after going down the pool. The water in the pond is deepened to meters in about 15 days.

Freshwater eels are carnivores and eat very little algae. It is mainly meat, but its predatory ability in nature is not very **, so in addition to preying on small fish, shrimp and some mollusks, it likes to eat the rotten or semi-decomposed corpses of various animals. This kind of somewhat decomposed carcass decomposes some free amino acids and fatty acids due to the action of microorganisms, and has a strong attractant effect on eels with a keen sense of smell.

Breeding, should be regarded as a relatively easy to raise special aquatic products, now the seed ** more restricting the development of eel breeding. After buying robust seedlings, they can be used in earthen ponds, cement ponds or water recycling, each with its own advantages and disadvantages. The main food eel compound feed can be, nutrition is comprehensive and convenient, other biological bait or live bait has to be processed every time is very troublesome, eel feed is generally powdered feed, mixed with water and into a puree to feed it, follow the principle of fixed-point timing and quantification, do a good job in water quality monitoring and disease prevention, diligent care.

In this way, the eels should be raised.

Electric eel, an eel-shaped South American fish of the family Bare Back Electric Eel, whose Latin scientific name is electrophorus electricus. It can produce enough electricity to stun people, and it is the freshwater fish with the strongest discharge ability, and the output voltage can reach 300 800 volts, so electric eels have water"High-voltage lines"called. [1] It is not a true eel, but is closely related to species of catiformes.

The electric eel was selected as one of the "most feared freshwater animals on the planet" by National Geographic**. [2] There are dozens of known species of fish in the world that generate electricity, and other fish that can discharge electricity include electric catfish and electric rays.

Habits. Electric eels often hunt at night, and their diet includes small fish, crabs, shrimp, crustaceans, and aquatic insects, as well as rotting carcasses of animals, and some individuals have higher plant detritus found in their food. When the electric eel hunts, it first quietly swims close to the fish, and then it can continuously release electric current, and the fish that have been shocked immediately faint and stiffen, so the electric eel takes the opportunity to devour them. The feeding intensity and growth rate of electric eels increased with the increase of water temperature, and were generally the highest in spring and summer.

The eel is a broad-salt, carnivorous fish. In nature, eel seedlings mainly feed on planktonic crustaceans, and when they grow up, they mainly feed on small shrimp, small crabs, aquatic insects, snails, clams, earthworms, etc., and also prey on small fish and detritus of higher plants.

Kabayaki eel rice for two servings.

1 river eel was cultured with feed.

When you buy eel, you can ask the store to help you handle the eel, remember to ask for bones and liver).

The first step in the practice.

Put the rice and water in the rice cooker and soak for half an hour, then turn on the fine cooking setting.

Step 2: Bake the eel bones in the oven at 200°C for 10 to 15 minutes, opening the door from time to time to see if they are not mushy.

The third step is to use a knife to draw a 5mm square diamond grid on the eel skin, so that the fat can flow out of these gaps during the later frying and at the same time, it will also make the sauce more flavorful.

Step 4: Put the eel in the steamer and steam for 10 minutes, the purpose is to remove part of the fat and make the fish bones soft, take it out and cool after steaming, do not do other treatments in the hot or it will be easy to disperse.

The fifth step is to make the juice - soak the kelp in mineral water for about 15 minutes, put it on the stove and cook it over medium heat, take it out at about 90°C before boiling, add a little mineral water to cool it, add bonito flowers, and continue to heat for 30

Remove from heat after a second and let cool.

Step 6: Heat the sake and mirin in a small pot and bring them to a boil to evaporate the alcohol.

Step 7: Add honey, soy sauce and grilled fish bones, continue to heat, pour in 3 cups of juice, continue to medium high heat throughout the whole process, and concentrate the sauce to 1 cup. (You can taste the flavor during this period and avoid being too light or salty).

Step 8: Put the cooled eel skin side down into a non-stick pan, and slowly bake the fish skin over medium-low heat, about 10 15 minutes, during which you can look at the degree of the skin in reverse, do not fry paste, but be crispy.

Step 9Put the fried eel on a baking sheet, brush the juice, set the oven to 200°C (or barbecue setting), bake for 4 minutes, take out and brush the juice for 4 minutes, repeat 4

Times. (During this period, you should always pay attention to the condition of the eel to avoid baking).

Step 10: After the fish is grilled, turn the eel upside down, brush the juice and grill the skin 2 times according to the method of grilling the fish.

Step 11. To make plum rice, remove the core of the pickled plums, chop them and mix them in the cooked rice.

Step 12. Remove the grilled eel, cut it into cubes, arrange it on top of the rice, and sprinkle with pepper powder.

You can eat it with seaweed, sesame seeds, wasabi or yuzu pepper, chopped green onions, or tea or eel liver soup like Nagoya Sanyu.

Eel, pinyin: pinyin: mán alias:

White eel, white eel, river eel, eel, blue eel, wind man, Japanese eel. Eel is a general term for species that belong to the order Eel. Also known as the eel, it is a fish that resembles a long serpentine in appearance and has the basic characteristics of a fish.

In addition, eels, similar to salmon, have migratory properties. Eels are snake-like but scaleless fish that are generally found in brackish and freshwater waters.

Eel has the effects of nourishing deficiency and nourishing blood, dispelling dampness, anti-tuberculosis, etc., and is a good nutritional product for patients with long-term illness, weakness, anemia, tuberculosis and so on. The eel contains a very rare Xihe Rock protein, which has a good effect of strengthening the kidneys, and is a health food for young couples and middle-aged and elderly people. Eel is a calcium-rich aquatic product, and regular consumption can increase the blood calcium value and make the body strong.

The liver of the eel is rich in vitamin A, which is an excellent food for people with night blindness.

The nutritional value of eel is not inferior to that of other fish and meat. Eel meat is rich in high-quality protein and various essential amino acids.

The eel vertebrae have almost everything needed for a perfect calcium source, so they are respected by scientists at home and abroad, and are recognized as "the ideal natural biological calcium source" and "the natural supplier of human calcium". The ratio of calcium and phosphorus in the eel vertebrae is close to 2:1, which is naturally consistent with breast milk, and is internationally recognized as the best ratio of calcium absorption, and the bioavailability of calcium contained in it is extremely high.

Eel calcium is a health food made of eel bone meal, oligosaccharides, vitamin D, and milk powder as the main raw materials, which has the health care function of calcium supplementation. Eel calcium is a natural biocalcium, which is safe and easy to absorb. Specially added isomalto-oligosaccharides, it has an excellent enhancement effect on the beneficial bacteria Bifidobacterium in the human intestine and can regulate gastrointestinal function.

Eels prefer to live in clean, unpolluted waters, and are the purest water creatures in the world, often hunting at night, eating small fish, crabs, shrimp, crustaceans and aquatic insects, and some individuals have higher plant detritus found in their food.

Eels are omnivorous fish that eat everything, and domestic ones may feed them garbage, such as dead lambs, dead chickens, and so on. I can't go on anymore, disgusting.
