Question 3: There are pictures of the fish, I would like to know what are the fish? What species is that sturgeon? Figure 1,
Carp Cyprinidae Tinca fish
The picture below shows Tinca tinca, also known as the European Tinca tinca, Tinca tinca, whisker fish years
The body length can be up to 70 centimeters, most of them are small in body size, with small, orange-red eyes. Heterogamy is not obvious, except that females have a more protruding abdomen than males. The outer spokes of the ventral fins also appear to be more robust and flattened in males. The body is slightly taller, ? Quercus residualis? laterally compressed. The body is olive-green in color, with the dorsal side of the body greenish-black, the dorsum darker, and the belly close to golden-yellow, more rounded and without leathery ribs. Body caudal fins do not diverge, the other fins are rounded, the fins are mostly gray and black, iridescent golden. It is not only a delicacy among the fish, but also an excellent product for breeding, ornamental and angling.
Figure 2 , not suitable for differentiation. It may be
Mylopharyngodon piceus
Figure 3,
German mirror carp is a kind of carp without scales, also known as scattered mirror carp (three scales), the species was introduced from the original West Germany varieties, after more than 20 years of systematic breeding of the Institute of Aquatic Research of Heilongjiang has been selected and bred for most areas of China's breeding of German mirror carp selection line. The German mirror carps have been selected for breeding in most areas of China.
The body shape is stout, laterally flattened, the back of the head is bulging, the head is smaller, the eyes are bigger, the scales on the body surface are bigger, arranged along the edge, there is a complete line of scales from the front end of the dorsal fin to the head, and there is a line of continuous and complete scales on each side of the dorsal fin which is opposite to each other, and there are scales on the bases of the fins, and there are a few scales on the lateral lines of the individual individuals. The lateral line is mostly straight and unbranched, with a shorter branch at the end of the lateral line in individual individuals.
Figure 4,
Acipenseridae fish (available for food and farming are hybrid sturgeon), can also be braised
Hybrid sturgeon if the parents of both sides of the *** with the same advantages, almost all sturgeon species can be obtained through crossbreeding hybrid sturgeon, the most used species, the European sturgeon, sturgeon, sturgeon, sturgeon, and so on, but spoon-nose sturgeon with other species of sturgeon. However, the keystone sturgeon and other species hybridization, the resulting fertilized eggs can not hatch successfully, may be the keystone sturgeon and other species of sturgeon between the existence of reproductive isolation. Two species hybridization, if you can get fertilized eggs, and successful hatching, only the two species in the species hybridization or a small part of the genus hybridization.
English name: bester
It has an extended carapace, a black back, a white belly, and is covered with 5 rows of bony plates, and is characterized by fast growth, high feed conversion, disease resistance, high nutritional value, and muscle free of miscellaneous spines.
Question 4: What is the difference between Chinese sturgeon and sturgeon? "Sturgeon" is the trade name of the sturgeon, sturgeon has a variety of briefly introduced as follows: Sturgeon (Sturgeon) is the world's existing fish in the large size, long life, the oldest kind of fish, so far there have been more than 200 million years of history, known as the "living fossil of the water! ". Sturgeon belongs to the sturgeon order, the world's existing sturgeon 2 families, 6 genera and 26 species, they are: Russian sturgeon, flash sturgeon, naked belly sturgeon, Siberian sturgeon, small body sturgeon, Shi's sturgeon, long-snouted sturgeon, Adriatic sturgeon, Chinese sturgeon, Dachshund's sturgeon, Japanese sturgeon, in kissing the sturgeon, the lake sturgeon, the short-snouted sturgeon, sharp-snouted sturgeon, high first sturgeon, multi-method sturgeon, Missouri shoveling sturgeon, Mississippi shoveling sturgeon, the big Amulet sturgeon, Amulet sturgeon, the small Amulet sturgeon, the Sill anime shoveler sturgeon, Yangtze white sturgeon, and spoon-nose sturgeon. Existing sturgeon are distributed in the Northern Hemisphere, there are mainly three distribution of dense areas: 1, the eastern part of Europe, the Caspian Sea, the Black Sea, the Aral Sea region; 2, around the two sides of the North Pacific Ocean in eastern Asia and western North America; 3, the east coast of North America There are eight species of sturgeon distributed in our country, mainly distributed in the Yangtze River, the Heilongjiang River, and the northwestern part of the three regions of Xinjiang: 1, the Yangtze River: the Chinese sturgeon, the Daciptera sturgeon, beluga sturgeon; 2, the Heilongjiang River; Sturgeon, Dachshund sturgeon; 3, Xinjiang Erqis River: Siberian sturgeon, small-bodied sturgeon; 4, Xinjiang Yili River: naked belly sturgeon Since April 1, 1998, the United Nations Washington Convention (CITIS) will be the world's wild sturgeon recognized as endangered species of protected animals. The Chinese sturgeon in the Yangtze River system is listed as a national-level aquatic protected animal, and the Shih's sturgeon, Dachshund's sturgeon, Siberian sturgeon, and small-bodied sturgeon are all economically important fish, all of which are listed as second-level protected animals. Sturgeon, whether in number, or species, mainly concentrated in Eastern Europe, the region's sturgeon production accounted for 80-90% of the world's production. Most sturgeons belong to the type between warm-water fish and cold-water fish, which are sub-cold-water fish, preferring to inhabit water bodies with lower salinity in the cold and temperate zones. Most sturgeons are migratory and semi-migratory fish. For example, juvenile Chinese sturgeon in the Yangtze River grow in the lower river and the sea, and the sexually mature groups go upriver from the shallow sea to the upper Yangtze River and the lower Jinsha River to reproduce. However, the construction of dams has impeded the reproductive migration of sturgeon and overfishing of sexually mature parent fish and other factors, resulting in a sharp decline in sturgeon resources. Among the 26 species of sturgeon, the largest production is: Russian sturgeon, flash sturgeon, Siberian sturgeon, small-bodied sturgeon. Followed by: Atlantic sturgeon, high sturgeon, lake sturgeon, Sturgeon, sturgeon, sturgeon, Chinese sturgeon, spoon-naped sturgeon. In the early 70's to the early 90's, the world's total sturgeon production in 15,000 tons - 40,000 tons. With the dissolution of the Soviet Union, so that the former Soviet waters management in the absence of *** state, in 1993 fell to 9594 tons, less than 10,000 tons, and currently estimated at less than 5000 tons. In recent years, due to environmental pollution, increased demand, overfishing and construction of hydropower projects, the natural production of sturgeon has been declining year by year, so that the sturgeon resources have declined significantly, and many species are in an endangered state. As the age of sexual maturity of sturgeon is generally late, it is difficult to recover after the destruction of resources; on the other hand, due to the international market for sturgeon products, especially sturgeon roe sauce demand is growing, to the development of sturgeon aquaculture has brought opportunities, *** the development of the world's sturgeon aquaculture industry. Currently on the market to sell the "sturgeon" are basically commercialized breeding of Russian sturgeon, businessmen in order to promote the need, often called "Chinese sturgeon" to attract customers. If the real sale of Chinese sturgeon is certainly illegal; but if the "Chinese sturgeon" signboard and the actual sale of captive-bred Russian sturgeon, in addition to the suspicion of fraud, is not illegal.

Question 5: What kind of fish is this? Sturgeon, right? Be specific. This is sturgeon, now common on the market is the European sturgeon, are artificially farmed, your home this should also be
Question 6: What kind of fish is this? Succulent fish (yín yú) that the sturgeon (xún yú) (Sturgeon), the ancient name ?S fish (xún
yú), body length 0.5-7 meters. Sturgeon is the world's existing freshwater fish in the large size, long life, an ancient fish, so far, there are more than 200 million years of history, originated hundreds of millions of years ago in the Cretaceous period, known as the "water panda" and "living fossil in the water," known as, the Department of the existing old biological Species. Sturgeons are kept as ornamental fish because of their peculiar body shape. The head of sturgeon is plow-shaped, the mouth is inferior, the tail is crooked, and the back of the body has 5 rows of bone plates. Both juvenile and adult sturgeon are of ornamental value, and the juveniles of the Shi's sturgeon (distributed in Heilongjiang) have been formally bred as ornamental fish since the success of artificial propagation. Most species of common individuals are in the tens of kilograms to hundreds of kilograms, the largest individual European sturgeon 1600 kilograms, China's largest individual Chinese sturgeon 600 kilograms
Problem 7: sturgeon love to eat what the Chinese sturgeon is a benthic fish, the diet is very narrow, is a carnivorous fish, the main work of a number of small or slow action of the benthic animals for food in the ocean, the main fish to feed on, the crustaceans, mollusks, the second less. Fewer mollusks. In the estuary, the juvenile Chinese sturgeon feeds on benthic fishes such as snakes and nymphs and scaly shrimps and clams, and generally stops eating during the spawning period.
Question 8: Why is the sturgeon called Chinese sturgeon 20 points The sturgeon has other relatives, and the Chinese sturgeon is endemic to our country, of course, named after China.
There are also Chinese white-cum-dolphins, Chinese autumn sand ducks, Chinese pounds and so on
But then, the Japanese naming is not the same, as long as Japan has the animal, people mutual naming it, they rushed to name for the Japanese what what what, crabs, monkeys, birds, beetles, a lot of people are called the Japanese what what what, in fact, where there are.
Question 9: sturgeon and sturgeon difference? Heilongjiang sturgeon: sturgeon, sturgeon, and their two life Heilongjiang large hybrid sturgeon, sturgeon grow fast and a little larger, the quality of the fish roe to be better,
Question 10: the difference between the Chinese sturgeon and sturgeon Chinese sturgeon is the national level of protection, and sturgeon is divided into many kinds.
Chinese sturgeon only in the Yangtze River, the Chinese sturgeon mouth with whiskers, body fat.
