What kind of fish is Northeast Songhua fish

Northeastern "Songhua Fish" is Mirror Carp

This fish has few bones and thick meat. It grows in the Yalu River and eats pine pollen since childhood, so it is named "Songhua fish". German mirror carp is a carp without scales, also known as scattered-scale mirror carp (three-scale). This variety was introduced from the former West Germany. After more than 20 years of systematic breeding by the Heilongjiang Fisheries Research Institute, a German mirror carp breeding system suitable for breeding in most parts of my country has been bred. The body is relatively sturdy, flat on the sides, with a bulge behind the head and back, a small head, large eyes, and large scales on the body surface, arranged along the edge. There is a complete row of scales from the front end of the dorsal fin to the head, and a row of symmetrical continuous complete scales on each side of the dorsal fin. There are scales at the base of each fin, and some individuals have a few scales on the lateral line. The lateral line is mostly straight and unbranched, and the end of the lateral line of some individuals may have a short branch.

Songhua fish is a fish introduced from Germany. It grows in the Yalu River and eats pine pollen since childhood. The pine pollen contains 268 active nutrients, so it is named "Songhua fish". The fish body is black and shiny, with a strong physique, few thorns and few scales. The meat is fresh, tender and smooth. The fish skin is elastic and has an excellent taste. The fish roe is smooth and fragrant. The fish body is rich in more than 20 kinds of amino acids necessary for the human body. It is the only precious fish among cold-water fish that has fish oil. It is a rare health food for modern people. Songhua fish has high requirements for the environment, so it is not easy to breed.

As the title says, the Northeastern "Songhua Fish" is the mirror carp. This fish has few bones and thick meat. It grows in the Yalu River and eats pine pollen since childhood, so it is named "Songhua Fish".

The German mirror carp is a carp without scales, also known as scattered-scale mirror carp (three-scale). This variety was introduced from the former West Germany. After more than 20 years of systematic breeding by the Heilongjiang Fisheries Research Institute, a German mirror carp breeding line suitable for breeding in most of my country's high-altitude areas has been developed.

The body is relatively stout, flattened laterally, with a bulge behind the head and back, a relatively small head, a relatively large eye chain, and relatively large scales on the body surface, which are arranged along the edge. There is a complete row of scales from the front end of the dorsal fin to the head, and a row of symmetrical continuous complete scales on each side of the dorsal fin. There are scales at the base of each fin, and a few scales can be seen on the lateral line of some individuals. The lateral line is mostly straight and unbranched, and the end of the lateral line of some individuals has a relatively short branch.

How long do carp live?

How long do the common fish we eat live?

1. Guppy

The average life span of guppies is about 1 to 2 years. Guppies are small ornamental fish, and their terrifying reproductive ability is amazing. Adult fish can basically produce a nest of small fish in one month, and the small fish can reach sexual maturity in 3 to 4 months and join the production army, so they are called million fish.

2. Traffic lights

The life span of traffic lights is about 2 to 3 years. After many generations of artificial breeding, traffic lights have come down from the altar, and there are many preferential prices of 10 yuan for 30. However, most traffic lights do not die of old age but because of gluttony or diseases such as ascites.

3. Lotus Lantern

When the Lotus Lantern appeared, the Red Light completely became a supporting role. Compared with the Red Light, the Lotus Lantern is like the legendary other people's children. The average life span of the Lotus Lantern is 5 years, and it may live longer if it is well cared for. The Lotus Lantern is also considered to be a relatively hardy lantern fish.

Most tetras are similar to the cardinal tetra or the red tetra, with an average lifespan of less than 5 years, depending on their body length.

4. Red Arrowfish

A classic fish species that many people remember, its average lifespan is about 5 years, but if it is well cared for, it should be able to live longer, after all, an adult fish can reach 10 centimeters.

5. Three Lake Fish

If you know about Sanhu fish or have read the previous article, you will know that Sanhu fish is a general term. The average lifespan of small shellfish is about 5 years, and the six-pointed fish is said to live 25 years! But... the following article will tell you why many people's fish do not live to the age they are said to live.

6. Thai fighting fish

Betta fish are small fish, and their life span is about 5 years. Depending on the breeding environment, the life span of both sexes is slightly different. However, the most brilliant time of betta fish is when they are young. After 2 years old, betta fish begin to age and may not be as lively as before.

7. Koi

The legendary longevity fish, the life span of carp in the wild may not be counted, but the average life span of koi is 80 years! However, there is a legendary koi "Hanako" in Japan that is said to have lived for 226 years. If a generation is 25 years, this koi has lived for at least 9 generations, so koi has the meaning of longevity.

However, the actual lifespan of fish is difficult to reach the ideal lifespan mentioned above. For small fish, the actual lifespan in an aquarium is about 3 years on average. Fish disease, power outages, high temperatures, and turbulent water quality all affect the physical fitness of fish. Large fish often die from tossing and accidents, such as jumping out of the tank and turning over the tank.

Fun Facts

First of all, the world's most recognized freshwater fish with the longest lifespan is the pike. Someone once caught a pike in the wild and released it. According to the label on the release tag, it was 267 years old... However, it is difficult to test a species with a long lifespan in the wild, so it is difficult to say whether a pike can live to 267 years old. I don't know how many generations it will take to accurately calculate it.

There are always two major unsolved mysteries in the fishing circle.

1. It is said that fish have no growth limit. As long as there is sufficient food and a high-quality environment, they seem to be able to grow indefinitely.

Giant catfish and giant carp are both relatively common individuals. For example, unlike the 5-10 catties carp on the market, carp weighing more than 30 catties is not uncommon, and carp weighing 60 catties is not a legendary existence. As for how old it is, I am afraid no one knows.

Note: Hanako (1751-1977), who lived for 226 years in Japan, weighed only about 13 kilograms.

2. The mystery of the 100-jin black fish.

Many people have heard of or seen snakehead fish weighing more than 100 kilograms. Of course, this is a special case. It is said that snakehead fish weighing more than 100 kilograms can eat cattle and sheep, and can overturn small boats, with a cry like a child. Many people have sworn that they have seen it, but there is no evidence so far.

It is called thunder dragon in China, and is called black fish, mullet or black fish in the market.

The largest snakehead fish that have been photographed and accurately measured are about 20 jin and 1 meter long. (Snakehead fish are not weighed.) Maybe the legend of the 100-jin snakehead fish is artificially fabricated, but some large lakes that have been around for many years always give people some unexpected super-limit fish, which has always been an unsolved mystery.

The life span of carp is recorded as up to 300 years. In my country, carp that have lived for more than 40 years are often found. Koi can also live for 60 to 70 years, and some "longevity stars" can even live to 100 to 200 years old.

Carp have a very long life span, and can live for more than 100 years. In captivity, they can live for more than 40 years. There is a simple and convenient way to calculate the age of carp: each of its scales is like the cross section of a tree trunk, with many circles from the center to the outside, sparse and dense, with sparse circles standing upright in the summer and dense circles growing in the winter. So just count them and you will know how many years it has lived.

Carp, also known as carp crooked fish, carp, hairy fish, red fish in Chinese, is a strong brown fish of the carp family, native to Asia and later introduced to Europe, North America and other regions. It is omnivorous.

Carp have large scales and two whiskers on each side of the upper jaw. They live alone or in small groups in calm ponds, lakes, and rivers with muddy bottoms and dense aquatic plants. They have the habit of migrating in places with small bodies of water.

Carp can live for more than 40 years under breeding conditions. Like koi, their lifespan is very long, 60 to 70 years (it is said that there are koi who are 200 years old).

Carp is a temperate freshwater fish native to Asia. It likes to live in warm lakes or slow-flowing rivers on plains. It has long been used as an ornamental fish or food fish in China and Japan, and is also cultivated as a food fish in European countries such as Germany.

In winter (especially under ice), it is basically in a semi-dormant state, and its body fat is consumed in winter. In spring, it craves high-protein food to replenish its skin. In late autumn, winter is coming. In order to accumulate fat, there will also be a peak period of "grabbing food", and it is also mainly high-protein bait.
