What are the rare species of sturgeon? What are the sturgeon species suitable for breeding in China?

There are nearly 10 species of sturgeon suitable for aquaculture in China, including Siberian sturgeon, flash sturgeon, Russian sturgeon, Sturgeon sturgeon, Chinese sturgeon, rayel, spoon sturgeon and several hybrid sturgeons. Among them, Siberian sturgeon and flash sturgeon have strong life adaptability, it is easier to domesticate artificial compound feed, the growth rate is relatively fast, the body color is gray and black, and the market is good.

The Chinese sturgeon has an average body length of about 40 cm, a maximum length of 130 cm, and a maximum weight of 600 kg. The body is spindle-shaped, the head is pointed and the snout is long, and there are 4 snout barbels in front of the mouth. The Atlantic sturgeon, also known as the Baltic sturgeon, is smaller than the European sturgeon, and although it produces more eggs, its population is controlled and its condition is stable.

The sturgeon has been the world's most important sturgeon fishery since ancient times, and has been the most important sturgeon fish breeding and release object in Russia and Azerbaijan for more than 50 years. The Yangtze River sturgeon, known as the giant panda in the water, is a freshwater sedentary fish, a rare wild animal unique to the Yangtze River in China, and a national first-class protected animal with a history of 100 million years.

Sturgeon has strict requirements for water quality, and likes to live in a water environment with high dissolved oxygen content, low water temperature and gravel substrate. The age of sexual maturity is late in Chinese sturgeon, males are 11 years old and weigh 50-100 kg, and females are 14 years old and weigh 160-250 kg; The males are 9-10 years old, and the females are more than 10 years old. On the other hand, the sturgeon has reached sexual maturity earlier, with females weighing about 10 kg and males weighing 5 kg already reaching sexual maturity. Sturgeon feed on benthic invertebrates and small fish.

The Persian sturgeon is a migratory fish mainly found in the Caspian Sea, and the main anadromous rivers are the Kura, Volga and Ural rivers. He grows twice as fast as the Russian sturgeon. The Siberian sturgeon is a sturgeon family and sturgeon.

The body is elongated, conical, and covered with 5 rows of bony plates, of which 1 row of dorsal plates, 11 19 bony plates.

The Chinese sturgeon is one of the most precious economic fish in China, with the characteristics of particularly fast growth rate, good meat quality, large fish seed and high economic value, and the prospect of breeding should be said to be the best among the sturgeon, but because it is a national first-class protection object, it must apply for a license to breed.

At present, the main sturgeon aquaculture species introduced in China are: Russian sturgeon, European sturgeon, small body sturgeon, spoon sturgeon and other more than a dozen species; At present, there are 8 wild sturgeons in China, mainly released in Heilongjiang, Ussuri River, Songhua River, Shi's sturgeon, Da's sturgeon, Sakhalin sturgeon; Chinese sturgeon, Da's sturgeon, and white sturgeon published in the Yangtze River and Jinsha River; the naked belly sturgeon published in Yining and other waters of Xinjiang; Siberian sturgeon published in the Irtysh River, the Brento Sea, and Bosten Lake in Xinjiang.

<> present, there are 27 species of sturgeon in the world. There are 8 species of sturgeon distributed in China's natural waters, namely: Sturgeon, Dax's sturgeon, and Sakhalin sturgeon distributed in the basins of Heilongjiang, Songhua River and Wumo Mountain. the nudibranched sturgeon distributed in the waters of Yining, Xinjiang and other places; Chinese sturgeon, Dahuiqiao's sturgeon and white sturgeon distributed in the Yangtze River and Jinsha River basins; Siberian sturgeon is distributed in the Irtysh River, the Brento Sea and Bosten Lake in Xinjiang.

There are 18 species of sturgeon:

1. Due to the influence of the three main factors of river damming, environmental pollution and overfishing, the sturgeon resources have been shrinking, and most of the existing eight species of sturgeon have been in a critical state: Sturgeon sturgeon, Sturgeon d'avia, Sakhalin sturgeon, Chinese sturgeon, Sturgeon d'Dar's, White sturgeon, Bichang naked belly sturgeon, and Siberian sturgeon (B. burner's sturgeon).

2. The main species that have been studied in artificial reproduction in various countries around the world are: small sturgeon, flash sturgeon, tall sturgeon, short-nosed sturgeon, Russian sturgeon, Chinese sturgeon, European sturgeon, spoon sturgeon, Dardor's sturgeon, and hybrid sturgeon using the principle of hybrid dominance to carry out interspecific and intergenus hybridization of sturgeon.

3. Hybrid sturgeon: Heilongjiang hybrid sturgeon, Russian hybrid sturgeon, artificially raised Shi's sturgeon, the first two are more common on the market, because the hybrid sturgeon is a commercial fish made of hybridization, so it does not belong to the international, national and other protected list species, is a species that can be sold.

2. The main species that have been studied in artificial reproduction in various countries around the world are: small sturgeon, flash sturgeon, tall sturgeon, short-nosed sturgeon, Russian sturgeon, Chinese sturgeon, European sturgeon, spoon's sturgeon, Dardor's sturgeon, and there are also hybrid sturgeons that use the principle of hybrid dominance to hybridize between sturgeon species and genus.

3. Hybrid sturgeon: Heilongjiang hybrid sturgeon, Russian hybrid sturgeon, artificial vertical barrage to raise Shi's sturgeon, the first two are noisy or more common on the market, because the hybrid sturgeon is a commercial fish made of hybridization, so it does not belong to the international, national and other protected list species, is a species that can be sold.

There are the following 18 species of sturgeon: 1. Due to the influence of the three main factors of river damming, environmental pollution and overfishing, the sturgeon resources have been shrinking, and most of the existing 8 species have been in a critical state: Spoon's sturgeon, Dar's sturgeon, Sakhalin's sturgeon, Chinese sturgeon, Darden's sturgeon, white sturgeon, naked belly sturgeon, and Slagberian sturgeon (B. shelly's sturgeon).

2. The main species that have been studied in captivity in various countries around the world are: small sturgeon, flash sturgeon, tall sturgeon, short-nosed sturgeon, Russian sturgeon, Chinese sturgeon, European sturgeon, sturgeon sturgeon, Dab's sturgeon, and hybrid sturgeon using the principle of hybrid dominance to hybridize sturgeon between species and genera. 3. Hybrid sturgeon:

Heilongjiang hybrid sturgeon, Russian hybrid sturgeon, artificially raised Shi's sturgeon, the first two are more common on the market, because the hybrid sturgeon is a commercial fish formed by hybridization, so it does not belong to the species of the international, national and other protected lists, it is a species that can be sold.

Today, sturgeon is concentrated in Eastern Europe, which accounts for 80 90 percent of the world's sturgeon production, both in terms of quantity and species. Sturgeon fish are mostly of the type between warm-water fish and cold-water fish, and are sub-cold-water fish, which prefer to inhabit cold and temperate water bodies with low salinity.

Sturgeon are mostly migratory and semi-migratory. For example, the juvenile Chinese sturgeon in the Yangtze River descends to the sea to grow, and the sexually mature population traces back to the upper reaches of the Yangtze River and the lower reaches of the Jinsha River to reproduce. However, due to factors such as damming and hindering the reproductive migration of sturgeon and overfishing of sexually mature broodstock, sturgeon resources have declined sharply.

According to statistics, there are 26 species of sturgeon in 2 families, 6 genera and 26 species in the world

1. Sturgeon are divided into sturgeon family and white sturgeon family;

2. Among them, the sturgeon family can be divided into the genus Sturgeon, Sturgeon, Sturgeon sturgeon, and Sturgeon sturgeon; The white sturgeon family is divided into the genus White Sturgeon and the genus Spoon Sturgeon;

1) The genus is divided into two species: European fish and Da's fish;
