Alipay Ant Manor Today's Answer

eel fry

Extended reading:

Eel fry is the fry of eel, which refers to the species under the classification of Anguilla, and is also called white eel, river eel, eel, etc. It usually spawns and breeds in deep sea, grows in fresh water environment, is rich in nutrition, delicious in taste, less prickly and fleshy, and has the functions of cooling and relieving summer heat, nourishing and strengthening the body, and has very high breeding value.

Why is eel fry called soft gold?

The artificial seedling raising technology of eels has never been broken, so the source of eel larvae can only be caught in the wild.

This is mainly because eels have a very special life history, and it is difficult to simulate them in artificial environment. In production, larvae are mainly obtained through natural fishing.

At the same time, the sex of eels is determined by the acquired environment. When the number of groups is small, the proportion of female fish will increase, while the number of groups will decrease.

In the early days, when the resources were abundant, the price was not high, but in the later period, the catch increased sharply and the resources decreased sharply, so the price was high.

Extended data:

Scientists found that this spawning ground was mainly because a lot of newly hatched larvae were collected here. The larva of eel is about 6 cm long and weighs 0. 1 g, but its head is narrow and its body is tall, thin and transparent like a leaf, so it is called "willow fish".

Its body fluid is almost the same as seawater, so it can be transported with ocean currents for a long distance with little effort.

It takes about half a year for the Kuroshio current to drift back from the spawning ground and then back to the seashore of Taiwan Province, and it began to metamorphose into a slender and transparent eel line, also known as "glass fish", one month before reaching the shore.
