Eel is the meat or whole of eel in the family Anguilla. Eel is a kind of fish. It looks like a snake, but it has no scales. It is usually found in the waters bordering fresh water in Yuxian County. Mainly distributed in China Yangtze River, Minjiang River, Pearl River Basin, Hainan Island and rivers and lakes.

There are 18 species of eels in the world, among which there are four families of Japanese eel, perch eel, Celebes eel and short fin eel in Taiwan Province Province, but only Japanese eel has the largest number, and the other three are rare. They have lived on the earth for tens of millions of years, but our understanding of them is only in recent decades. For example, its real spawning ground was found in 199 1 year. Its sex was initially controlled by environmental factors and density. If the density is high and the food is insufficient, it will become a male fish, and vice versa. In the rivers of Taiwan Province Province, because the number of eels is very small, most of them are female.

Eel fry cannot be cultivated by artificial propagation, mainly because the life history of eels is very special and it is difficult to simulate in artificial environment. Japanese eels grow up in freshwater rivers and become adult eels. In summer, they begin to migrate to the sea, that is, they swim from the river to the ocean to lay eggs, which is just the opposite of trout and salmon in the middle reaches of the ocean migrating upstream to the river to lay eggs. Its spawning ground is in the deep sea thousands of kilometers between the Philippines and Malaysia. Scientists found this spawning ground mainly because a large number of newly hatched larvae gathered here.

The larva of eel is about 6 cm long and weighs 0. 1 g, but its head is narrow, its body is tall, thin and transparent as leaves, so it is called "willow fish". Its body fluid is almost the same as seawater, so it can be transported over a long distance by ocean currents with no effort. It takes about half a year for the Kuroshio current to return from the spawning ground to the seashore of Taiwan Province Province, and it begins to metamorphose into a slender and transparent eel line, also known as "glass fish", one month before reaching the shore. Therefore, every year from June 5438+02 to June 5438+00, fishermen will be busy fishing eel lines that are about to return to the river on the coast near the estuary and sell them to farmers. After the farmers bought it back for stocking, the color slowly appeared, turning into yellow young eels and silver adult eels. Under natural conditions, the largest individual that can be caught is 45cm and weighs1600 g.

Eels spawn and breed in deep sea and grow in fresh water. Fierce temperament, gluttony, active, staying up late during the day and coming out at night, strong optical rotation, like running water, so warm.

Adult eels grow fast, and their appearance is round, conical and dark, which is pleasing to the eye. In recent years, artificial breeding has been carried out, and the meat is crisp. This kind of fish is common all year round, but the fish in Xia Dong is the most delicious in two seasons. Eel is rich in nutrition, delicious, with less thorns and more meat, and has the functions of relieving summer heat, nourishing and strengthening the body.

In addition, Monopterus albus, belonging to Compositae and fish, is also like a snake, with no scales and yellow belly, hence the name Monopterus albus. Monopterus albus was born in a mud hole on the bank of a pond or freshwater river, and it is difficult to survive without water. When I was caught, I was covered in saliva and foam. Monopterus albus is not only a delicious food with tender meat, but also has been recognized as having nourishing and medical functions since ancient times.

Eel refers to the general name of species belonging to eel classification. Also called eel, it is a kind of fish that looks like a long snake and has the basic characteristics of fish. In addition, eels have similar migration characteristics to salmon.

Be distributed

Eels all over the world mainly grow in tropical and temperate waters. Except European eel and European eel, they are all distributed in Indian Ocean and Pacific Ocean.

biography

Eels grow in rivers on land, and when they mature, they migrate to spawning sites in the ocean to lay eggs. They only lay eggs once in their lives and die after laying eggs. This lifestyle, contrary to the anadromous salmon, is called anadromous salmon. Its life history is divided into six different development stages, and in order to adapt to different environments, the body shape and body color of different stages have changed greatly: egg stage: located in deep-sea spawning ground.

Leptospira: In the ocean, it drifts with ocean currents for a long distance. At this time, its body is flat and transparent, as thin as willow leaves, which is convenient to drift with the current.

Glass eel: When approaching the coastal waters, the body becomes streamlined, reducing resistance to get rid of strong ocean currents.

Elvers: When entering the estuarine waters, melanin began to appear, but it also formed the catch source of eel fry in aquaculture.

Monopterus albus: During the growth of the river, the belly of the fish is yellow.

Silver eel: When mature, the fish turns silvery white like deep-sea fish, and at the same time, the eyes become bigger and the pectoral fins become wider to adapt to swimming back to the deep sea to lay eggs.

The sex of eels is determined by the acquired environment. When the number of groups is small, the proportion of female fish will increase, and when the number of groups is large, it will decrease. The overall proportion is conducive to the increase of groups.

prepared food

Freshwater eel (ぅなぎ; Unagi) and sea eel (Ji Kang eel; Kangji Eel, Anago). Eels are also commonly used in Cantonese and Shanghai cuisine. European eels and other freshwater eels are eaten in Europe, America and other places. A traditional London dish is frozen eel.

Similar species

The stinging eel and Artemia in invertebrates are also very similar to eels.

These deep-sea fish used to belong to the suborder Leucoptera. Electric eels are not eels, but catfish. Real eels belong to the class of eels in bony fish.

other

In Europe, only Britain can legally catch eels by hand. For thousands of years, people have been throwing nets to catch eels in the Paret and Severn rivers in England.
