Taiwanese silktail conger eel.

The total length of the Taiwanese silktail conger eel is centimeters. It belongs to the genus Fibretail. It is found in the Indian and Pacific Oceans.

It is a warm-water demersal fish, generally preferring to inhabit sediment-bottomed sea areas at depths of 50 to 80 meters, and has seasonal migration. It feeds mainly on fish and invertebrates. Sexual ferocity, gluttony.

On sunny days, when the wind is calm and the sea water is transparent, they tend to live in muddy caves and reduce feeding activities. Whenever the wind and waves are strong and the water is turbid, they tend to forage for food, especially from sunset to early morning, they are more active and swim quickly. The food is mainly shrimp, crab, small fish, and octopus.

The spawning period is generally in spring or summer, and the number of eggs is about 181.2 million, and the spawning grounds are mostly in mud or sediment. The meat is tender and has a high fat content; The swim bladder can be used as fish maw and is a valuable food. Moray eels lay a wide range of eggs.

The spawning period is at the beginning of summer, and the absolute fertility is 181.2 million seeds.

Not long ago, in the sea of Zhoushan, I caught a large eel that was 75 kilograms long and long.

Eel species:

European eel, Anguilla anguilla, Japanese eel, Anguilla japonica, white eel, Australian eel, Anguilla australis, black eel, African eel, Anguilla Mossambica, perch eel, Anguilla mormorata, Filipino eel, Anguilla mormorata, New Zealand eel, Anguilla dieffenbachi, Indonesian eel, Anguilla There are 18 species of Bicolor Pacifica eels in the world.

There are 18 species of eels in the world, of which Taiwan has four families: Japanese eel, perch eel, Celebes eel and shortfin eel, but only the Japanese eel is the most, and the other three are rare.

Eel fry cannot be bred by artificial propagation, mainly because eels have a very special life history and are difficult to simulate in an artificial environment.

Japanese eels grow into adult eels in freshwater rivers and begin to migrate from rivers to the ocean to spawn in the summer, as opposed to anadromous migrations in which trout and salmon swim back to rivers to spawn.

Its spawning grounds are thousands of kilometers away, in the deep sea between the Philippines and Malaysia's Na Islands.

Scientists discovered this spawning ground mainly because of the large number of its newly hatched larvae harvested here.

The types of eels are Celebes eel, American eel, Japanese eel, and Australian eel

Celebes eel, a descending migratory fish, resembles a snake in appearance and has relatively small scales. It usually inhabits estuarine, freshwater, and offshore coasts, and is mainly found in the Philippines, Indonesia, and western New Guinea.

American eel, mainly produced in the United States, Canada and other places, introduced in China in 1996, stocked in Jiangsu, Zhejiang, Fujian, Guangdong and other coastal provinces.

1. European eel: The adult of the European eel spends time in fresh water and usually hunts after dark, the prey is mainly small animals, and its life cycle has been a mystery for many years, in 1920, an ocean-going study showed that the adult European eel would cross the Atlantic Ocean to the Sargassum Sea to spawn, and then the adult European eel would die and leave the juveniles to return to Europe by themselves, the trip would take 3 years, another similar eel lived in North America, and the journey from the Sargassum Sea took only 1 year.

2, American eel: American eel is mainly produced in the United States and Canada and other places, in 1996 China officially introduced American eel mainly stocked in Jiangsu, Zhejiang, Fujian, Guangdong and other coastal provinces, the number of introduction of as much as 6 tons, such as Dong County Nangang fishing net factory on April 12, 1996 to introduce American eel seedlings kilograms for trial breeding.
