If you are satisfied, please accept it. Thank you.
Question 3: There are pictures of fish. What kind of fish do you want to know? What kind of sturgeon is that? Figure 1,
Cyprinidae? Ding fish of the first kind
The picture below shows Ding? I'm Tinca tinca, aka Odin? I, Ding Guiyu, Yu Xusui.
The body length can reach 70 cm, and most of them are smaller, with small eyes and orange-red. Androgyny is not obvious, but the abdomen of female fish is more prominent than that of male fish. The outer radial ribs of male ventral fins also seem to be thicker and flatter. Slightly higher, disabled? Side flat. Generally olive green, black on the back, deep on the back, close to golden yellow on the abdomen, round, without skin edges. The tail fin of the body is not bifurcated, and the other fins are round, mostly gray-black and iridescent gold. It is not only delicious in fish, but also a good product for breeding, viewing and fishing.

German mirror carp is a kind of scalless carp, also known as loose scale mirror carp (three scales). This variety was introduced from the former West Germany. After more than 20 years of systematic breeding, Heilongjiang Fisheries Research Institute has bred a breeding line of German mirror carp suitable for breeding in most areas of China.
The dorsal fin is thick, flat on the side, with protrusions on the back of the head, small head, big eyes and large scales on the body surface, which are arranged along the edge. There are 1 rows of complete scales from the front end of dorsal fin to the head, and 1 rows of symmetrical and continuous complete scales on both sides of dorsal fin. There are scales at the base of each fin, and a few scales can be seen on individual lateral lines. Most lateral lines are straight without branches, and some lateral lines have short branches at the end.
Figure 4,
Fish of the sturgeon family (both edible and cultured are hybrid sturgeons) can also be braised in brown sauce.
If the hybrid sturgeon has the same advantages as both parents, almost all sturgeon species can be hybridized to obtain hybrid sturgeon. The most commonly used species are ACIPENSER europaeus, ACIPENSER schrenckii, ACIPENSER Dalbergiae and ACIPENSER sinensis, but the fertilized eggs obtained by crossing with other species cannot hatch successfully, which may be due to the reproductive isolation between ACIPENSER schrenckii and other species. If two varieties cross, if fertilized eggs can be obtained and hatched successfully, only these two varieties cross within the species or a small number cross within the genus.
English name: bester
Its body is slender, its back is black, its abdomen is white, and its body is covered with five ribs. It has the characteristics of fast growth, high feed conversion rate, strong disease resistance, high nutritional value and no muscle thorn.
Question 4: Is there a difference between Chinese sturgeon and sturgeon? "Sturgeon" is the commercial name of sturgeon. There are many kinds of sturgeon, which are briefly introduced as follows: sturgeon is the oldest fish in the world, with a history of more than 200 million years, and is called "living fossil in water". Sturgeon belongs to sturgeon order, and there are 26 species of sturgeon in the world, belonging to 2 families and 6 genera. They are: Russian sturgeon, flash sturgeon, naked-bellied sturgeon, Siberian sturgeon, small sturgeon, sturgeon schrenckii, long-snout sturgeon, Adriatic sturgeon, Chinese sturgeon, shad, Japanese sturgeon, middle-snout sturgeon, lake sturgeon, short-snout sturgeon and pointed-snout sturgeon. The existing sturgeons are all distributed in the northern hemisphere, mainly concentrated in three dense distribution areas: 1, eastern Europe, Caspian Sea, Black Sea and Aral Sea; 2. Eastern Asia and western North America around the two sides of the North Pacific; 3. There are 8 species of sturgeon along the east coast of North America in China, mainly distributed in the Yangtze River, Heilongjiang and northwest Xinjiang: 1, and the Yangtze River: Chinese sturgeon, sturgeon and paddlefish; 2. Heilongjiang; Acipenser schrenckii and bighead carp; 3. Irtysh River in Xinjiang: Siberian sturgeon and small sturgeon; 4. Ili River in Xinjiang: Bare-bellied Sturgeon 1 Since 1 April, 9981,the United Nations Washington Convention (CITIS) has recognized the world wild sturgeon as an endangered protected animal. The Chinese sturgeon in the Yangtze River system is listed as a national first-class aquatic protected animal, while Acipenser schrenckii, ACIPENSER schrenckii, ACIPENSER Siberia and ACIPENSER schrenckii are all important economic fish and are listed as second-class protected animals. No matter the number or species of sturgeon, it is mainly concentrated in Eastern Europe, where the sturgeon production accounts for 80-90% of the world's production. Sturgeon mostly belongs to the type between warm-water fish and cold-water fish, belongs to sub-cold-water fish, and likes to live in cold regions and temperate waters with low salinity. Most sturgeons are migratory and semi-migratory fish. For example, the juvenile Chinese sturgeon in the Yangtze River grows in the sea, and the sexually mature population migrates from the shallow sea to the upper reaches of the Yangtze River and the lower reaches of the Jinsha River to breed. However, due to factors such as dam construction, blocking the reproduction and migration of sturgeon and overfishing mature parent fish, the sturgeon resources have dropped sharply. Among the 26 species of sturgeon, the largest output is Russian sturgeon, Amur sturgeon, Siberian sturgeon and small sturgeon. Followed by: Atlantic sturgeon, high-headed sturgeon, lake sturgeon, Shi sturgeon, Darwin sturgeon, Chinese sturgeon and white sturgeon. From the early 1970s to the early 1990s, the total output of sturgeon in the world was1.5,000-40,000 tons. With the disintegration of the Soviet Union, the water resources management in the former Soviet Union has declined from 1.993 to 9,594 tons, less than 1 10,000 tons, and now it is estimated to be less than 5,000 tons. In recent years, due to environmental pollution, increasing demand, overfishing and the construction of hydropower projects, the natural output of sturgeon has been declining year by year, which has greatly reduced the sturgeon resources and many species are in an endangered state. Due to the late sexual maturity of sturgeon, it is difficult to recover the resources after being destroyed; On the other hand, the demand for sturgeon products, especially sturgeon caviar, is increasing in the international market, which brings opportunities to the development of sturgeon breeding industry and greatly promotes the development of sturgeon breeding industry in the world. At present, the "sturgeon" sold in the market are basically Russian sturgeon raised commercially, and merchants often call it "Chinese sturgeon" for the purpose of promotion to attract customers. If you really sell Chinese sturgeon, it is definitely illegal; However, it is not illegal to actually sell artificially raised Russian sturgeon under the signboard of "Chinese sturgeon", except for those suspected of fraud.

Question 5: What kind of sturgeon is this? Specifically, it is sturgeon. The common sturgeon on the market now is European sturgeon, all of which are farmed artificially. So should your family.
Question 6: What kind of fish is this? Ill fish (yín yú) means sturgeon (xú n yú), which was then called? S fish (xún
Yú), with a body length of 0.5-7m. Sturgeon is a large, long-lived and ancient freshwater fish in the world. It has a history of more than 200 million years, which originated in Cretaceous hundreds of millions of years ago. Known as "panda in water" and "living fossil in water", it is an existing ancient biological population. Sturgeon is kept as an ornamental fish because of its peculiar shape. Sturgeon has a plow-shaped head, a low mouth, a curved tail and five ribs on its back. Both juvenile and adult fish have ornamental value, among which the juvenile ACIPENSER schrenckii (distributed in Heilongjiang Province) has been artificially raised as an ornamental fish since its successful artificial reproduction. The common individuals of most species are tens to hundreds of kilograms, the largest individual of European bighead carp is 1600 kilograms, and the largest individual of Chinese sturgeon is 600 kilograms.
Question 7: What does sturgeon like to eat? Acipenser sinensis is a kind of benthic fish with very narrow feeding habits and belongs to carnivorous fish. Its main food is some small or slow-moving benthos, and the main fish in the ocean are crustaceans, followed by mollusks. The juvenile Chinese sturgeon in the estuary mainly feeds on benthic fishes, such as Ophiuchus, pupae, krill and Agkistrodon halys, and generally stops feeding during spawning period.
Question 8: Why is the sturgeon called Chinese sturgeon 20 points? The sturgeon has other relatives. The Chinese sturgeon is unique to China, and of course it is named after China.
There are also Chinese baiji, Chinese merganser and Chinese Maggie.
However, Japanese names are different. As long as some animals in Japan name each other, they will soon be named Japanese, crab, monkey, bird and beetle. Many of them are called Japanese, but they are everywhere.
Question 9: What's the difference between sturgeon and bighead carp? There are three kinds of sturgeons in Heilongjiang province: ACIPENSER sinensis, ACIPENSER schrenckii and their two hybrid sturgeons in Heilongjiang province. Mandarin fish grow faster and bigger, and the quality of fish eggs is better.
Question 10: the difference between Chinese sturgeon and sturgeon. Chinese sturgeon is a national first-class protected animal, and there are many kinds of sturgeon.
Acipenser sinensis lives only in the Yangtze River. Chinese sturgeon has a beard on its mouth and is relatively fat.
Acipenser sinensis: Acipenser sinensis is endangered and is a national first-class protected animal.
