The eel is not an eel
No. The eel is an eel that belongs to the family of eels. Eel is a general term for species belonging to the classification of the eel order, a fish, like a snake, but without scales, generally produced in the fresh and salt water interface waters. Eel belongs to the eel order, eel family, eel genus. Also known as eels, eel, fish, eel, snake fish, blood eel, often fish, long fish. Eels like to live in clean, unpolluted waters and are the purest water creatures in the world. Eels often live in paddy fields, creeks, streams, ponds, rivers, canals, lakes and other silty water bottoms.
How does the eel reproduce
The freshwater eel is a descending river migratory fish, native to the sea, anadromous to the freshwater within the grown up, and then returned to the sea to spawn. Every spring, a large number of young eels (also known as white children, eel line) from the sea into the mouth of the river in groups.
Eels spawn and reproduce in the deep sea, and grow up in freshwater environments. Fierce temperament, gluttony, good movement, day and night, tend to rotating light strong, like running water, good warmth.
Eel fry cannot be bred by artificial propagation, mainly because eels have a very special life history, which is difficult to simulate in an artificial environment. The Japanese eel grows into an adult eel in a freshwater river, and in the summer, it starts to migrate down to the sea, that is to say, it swims from the river to the ocean to spawn, which is the opposite of the anadromous migration of trout and salmon, which swims from the ocean back to the river to spawn.
The eel's young is about 6 centimeters long and weighs 0.1 grams, but its head is narrow and its body is high, thin, and transparent like a leaf, so it is called a "willow leaf fish". Its body fluid is almost the same as seawater, so it can be drifted along with the ocean current for a long distance with little effort.
It takes about half a year to drift from the spawning grounds back to the Kuroshio Current and then back to the coast of Taiwan, and only a month before it reaches the shore does it begin to metamorphose into the long, thin, transparent eel threads that are also known as the "glass fish". That's why fishermen are busy catching eel threads that are on their way back to the coast near the mouth of the estuary with hand nets from December to January every year to sell them to farmers.
Whether eels are farmed or wild
To recognize whether they are wild or farmed, it is important to know the type of eel. Eel is divided into sea eel and eel and many other families, varieties are very much, only the sea eel has more than 50 species, eel also has 10 species. Sea eel is living in the sea, can not survive in fresh water, eel is in the sea spawning, young mature back to the freshwater river life, those live eels on the market is mainly eel, because the sea eel is unable to use fresh water to raise, on the stalls to sell are dead. Eel, also known as white eel, body elongated, the front part of the near-cylindrical, the rear part of the lateral compression, dorsal fins, anal fins and caudal fins are connected to the conjunction, there are scales, but buried in the skin, very small, to use a microscope in order to see the body of the mucus, the body of the upper grayish-black, the side of the upper edge of the green, the body of the white, the origin of the seawater, a little bit like a snake.
The sea lamprey looks much more fierce than the eel, and the color is also blacker than the eel, with powerful teeth in both jaws, and a scale-free body, with the dorsal side of the body in dark gray, the lower side in gray, and the dorsal and anal fin edges in black. At present, the eels on the market are mainly wild ones, even if they are farmed, most of them are captured and raised temporarily. Because of the high cost of raising moray eels, raising a long time, the farmers are not cost-effective.
The sea eel is bigger than the eel, the eel is usually between 500g-1000g, the sea eel is usually more than 3kg.
What kind of fish is eel
Eels are fish in the genus Anguilla of the family Anguillidae of the order Eeliformes. They have a unique appearance, more like a snake, and have no scales. They are mainly found in tropical and temperate waters. They are carnivorous fish and can eat fish, shrimp, crabs and other animals. They are not very large, generally not more than 1 meter in length. They can be farmed artificially, but artificially farmed individuals will be small in size, mostly around 40-50 centimeters in length.
