CATDOLL : CATDOLL: Can eels be farmed?

1. Can eels be farmed artificially?

Yes. The eels sold on the market now are all farmed. There are not so many wild ones.

2. Can electric eels be artificially cultivated in China?

To identify whether it is wild or farmed, you must first understand the type of eel. Eels are divided into multiple families such as conger eels and eels, and there are many species. There are more than 50 species of conger eels alone, and there are about 10 species of eels. Conger eels live in the sea and cannot survive in fresh water. Eels lay eggs in the sea, and when the young mature, they return to live in freshwater rivers. The live eels on the market are mainly eels, because conger eels cannot be raised in fresh water, and the ones sold on the stalls are all dead.

The eel, also known as the white eel, has a slender body that is nearly cylindrical in the front and laterally flattened in the back. The dorsal fin, anal fin and caudal fin are connected. It has scales, but they are buried under the skin and are very small. They can only be seen under a microscope. There is a lot of mucus on the body. The upper part of the body is gray-black, the upper edge of the side is green, and the lower body is white. It is native to seawater and looks a bit like a snake.

Conger eels look much more ferocious than eels, and are darker in color than eels. They have strong teeth in their jaws, no scales, dark gray on the back, grayish white on the underside, and black edges on the dorsal and anal fins. Conger eels on the market are mainly wild, and even if they are farmed, they are mostly caught and kept temporarily. Because raising conger eels is very expensive, it is not cost-effective for farmers to keep them for a long time.

Conger eels are larger than eels. Eels generally weigh between 500 grams and 1,000 grams, while conger eels generally weigh more than 3 kilograms.

3. Is the eel a marine fish or a freshwater fish? Can it survive in fresh water?

Eels have the characteristic of migration. Sometimes they live in seawater and sometimes in freshwater. Therefore, they are quite special. They can be said to be both marine fish and freshwater fish. When eels are still relatively young, they live in rivers, lakes and other freshwaters. When they reach a certain age and their bodies mature and need to reproduce, they will go to the ocean to reproduce. This is their migratory habit.

1. Is eel a marine fish or a freshwater fish? Eel is a kind of fish. If we classify fish based on their living environment, they can be divided into marine fish and freshwater fish. The difference between marine fish and freshwater fish is quite large, and their living environments are very different. But eels are quite special, and they cannot be classified into one of them, because they can be said to be both freshwater fish and marine fish.

Eels first live in fresh water, and their growth and development process is carried out in fresh water such as rivers and lakes on land. When they reach a certain age, they will go to the ocean to reproduce. This habit is what we often call migratory habits. The process of eels spawning is completed in the ocean, and they can only spawn once in their lifetime. This phenomenon is also called catadromous migration.

2. Can eels live in fresh water? As mentioned above, eels have the characteristics of migration. When eels are still relatively small, they live in fresh water, and they can be seen in rivers and streams. When they reach mature age and need to reproduce, they will go to the ocean to reproduce, and eels can only lay eggs once in their lifetime. It can be seen that eels can live in fresh water. In fact, their growth and development process is carried out in fresh water. In addition, artificially raised eels generally live in fresh water. If they are raised, fresh water can be used, and they will not be unable to adapt.

4. Will the eel die if I buy it and put it in water? Is the eel a marine fish or a freshwater fish?

After you bring an eel home, it can usually survive for about 7 days, and then it may die due to poor water quality. When handling eels, you can first insert an ice pick into the eel's head, then use the back of a knife to hit the ice pick to fix it on the chopping board, then use a knife to cut the eel's belly from bottom to top, take out the internal organs, then use the knife to insert along the edge of the eel's spine to separate the body from the spine, and finally insert the knife into the gap between the eel's spine and the back to completely cut it off. After separating the bones and meat, you can wash the eel meat with clean water and use it as needed when cooking.

1. Will the eel die if I buy it and put it in water?

1. Survival time

Eels have high requirements for water quality. After you buy them home and put them in a bucket, they can generally survive for about 7 days, after which they may die due to poor water quality.

2. Treatment method

(1) Insert the ice pick into the eel’s head from one side and tap the ice pick with the back of a knife to secure it to the cutting board.

(2) Use a knife to cut along the eel’s belly from bottom to top, then take out the internal organs.

(3) Use a knife to insert along the edge of the eel's spine, separate its body from the spine, and then insert the knife into the gap between the eel's spine and back until the gap is completely cut.

(4) After the meat and bones are separated, soak and wash the eel meat in clean water and use it as needed when cooking.

2. Is eel a marine fish or a freshwater fish?

1. Eels are both marine fish and freshwater fish. They usually grow in freshwater rivers and migrate to the ocean to lay eggs when they mature. They can only lay eggs once in their lifetime and will die after laying eggs.

2. Eels are mainly distributed in the Yangtze River, Pearl River, Minjiang River and other water systems in my country, as well as in Hainan Island and some other rivers and lakes. Eels like to live in clean, unpolluted waters, and in order to adapt to the living environment, they will change their body shape at different stages.

3. Eels have six growth stages, namely the egg stage, leaf eel, glass eel, eel line, yellow eel and silver eel. Since they lay eggs in the ocean, it is impossible to directly obtain their eggs for hatching and breeding. Instead, they are caught by eel lines on the coast near the estuary and then sold to farmers for artificial breeding.
