Goldfish herring carp carp large yellow croaker grass carp is not the same kind of what?

Big yellow croaker is not of the same kind.

Larimichthys crocea, bony fish, perciformes, totoaba (sciaeni-dae), yellow croaker, also known as yellow croaker, kingfish, big fresh, big yellow croaker, red melon, golden dragon, ** dragon, osmanthus yellow croaker, big zhong, red mouth, totoaba, stonefish, cucumber fish, one of the traditional "four seas" (big yellow croaker, small yellow croaker, hairtail fish, squid), is the main economic fish in China's coastal waters.

Large yellow croaker, elongated, flattened laterally, about 40-50cm long. Golden. The caudal peduncle is elongated.

The scales are small, with 8-9 rows of scales between the beginning of the dorsal fin and the lateral line. 25-27 vertebrae. It usually inhabits deep sea areas, migrates to offshore waters from April to June to spawn, and after spawning, disperses along the coast to seek bait and feeds on fish and shrimp.

In autumn and winter, it migrates to the deep sea again. The swim bladder is a vocal sound, which is often used by fishermen to estimate the size of the fish. It is found in the South China Sea, the East China Sea and the southern Yellow Sea.

It is an important economic fish in China. for fresh food or making yellow croaker, etc.; The swim bladder can be made into glue. It has been artificially farmed.

Goldfish are different from the other four types of fish, the other four are edible, and goldfish are ornamental.

Large yellow croaker. The other fish are all freshwater fish, and all are carps; The large yellow croaker is a marine fish and is a perciformes.

The green croaker is the naked sturgeon. The scientific name of the blue croaker is the naked sturgeon, which is native to the Black Sea.

Caspian and Aral Sea basins, former Soviet Union.

In 1933-1934 it was introduced into Lake Balkhash, and now it has entered the Ili River system in our country.

Distribution of the origin of the nudibranched sturgeon:The naked belly sturgeon is also known as the sturgeon fish.

It is endemic to the Ili River. The Ili River is the only river in China where the naked sturgeon grows, and the naked sturgeon is naturally distributed only in the Black Sea, Caspian Sea and Aral Sea systems in Europe, and the number is very small.

The Ili River is the largest international river in Xinjiang, and its upper reaches have three major tributaries: the Turks River, the Gongnaisi River and the Kashgar River.

As a link between China and Kazakhstan, the Ili River makes Hanoi due to its special geographical location.

The composition of fish naturally communicates and spreads with each other, showing obvious characteristics of mixed species between Asia and Europe, which is completely different from the species of the Yangtze River system.

Yellow croaker is a naked-bellied sturgeon. Yellow croaker, known as the naked sturgeon, is native to the Black, Caspian and Aral Sea basins. From 1933 to 1934, it was introduced into Lake Balkhash by the former Soviet Union, and has now entered the Ili River system in China.

Origin distribution of the nudibranched sturgeon: The nudibranched sturgeon, also known as the sturgeon, is a species endemic to the Ili River. The Ili River is the only river in China where the naked sturgeon grows.

The naked belly sturgeon is naturally distributed only in the Black Sea, Caspian Sea and Aral Sea systems in Europe, and the number is small. The Ili River is the largest international river in Xinjiang, with three tributaries in its upper reaches: the Turks River, the Gongnaisi River and the Kashgar River. Most of these tributaries are pebble beds and are spawning grounds for some fish.

As a link between China and Kazakhstan, the Ili River naturally communicates and spreads fish composition with each other due to its special geographical location, showing obvious characteristics of mixed Asian and European species, which is completely different from the Yangtze River water system.

No, it's two fish that look similar. Herring eats meat, grass carp eats grass x0d x0a herring is one of the most common and unique freshwater aquaculture fish in China, distributed in the Yangtze River, Pearl River and its streams, and the population is small in the Yellow River, Heilongjiang and other northern water systems. Herring lives in the lower layers of the water and feeds mainly on snails, clams and young mussels, as well as shrimp and aquatic insects.

The spawning period in the Yangtze River, Pearl River and Xijiang River is 3 June; Slightly later in the northeast; Spawning broodstock can be tens of catties and hundreds of catties. With the Yangtze River and Xijiang River as the most important production areas, the pond breeding industry is developed, and it can grow to five kilograms in three years, which has important economic value. x0d x0a I. Morphological characteristics and measurable and countable traits of herring:

The snout is blunt, whiskered. Lateral position of the eye. The gill rakers are sparse and short, the lower pharyngeal teeth are molar-shaped, the wheezing surface is smooth and grooveless, the lateral line is intact, the body is covered with large garden scales, the dorsal fin and anal fin are not hard, the caudal fin is deeply forked, the upper and lower are of equal length, the bladder is two-chambered, the posterior chamber is longer than the anterior chamber, the peritoneum is black, the body is blue-black, and the back is deeper.

X0d X0a grass carp has an elongated body, a slightly subcylindrical trunk, a flattened tail, no ventral ridge, a medium-sized head, a broad and flattened snout, an arc-shaped mouth, and a slightly prominent upper jaw. The gill rakers are short, rod-shaped, and sparsely arranged. The hypopharyngeal teeth are comb-like tentenoids with large scales and rounded shapes.

The lateral line is slightly curved, extending posteriorly to the middle of the caudal peduncle, the dorsal fin is free of hard spines, the starting point is opposite the beginning of the pelvic fin, and it is slightly farther from the snout than from the base of the caudal fin. The anal fin has no hard spines, and the origin is closer to the base of the abdomen than from the base of the caudal fin. The body of the fish is tea-yellow, the back is grayish-gray, the abdomen is grayish-white, the pectoral and caudal fins are grayish-yellow, and the rest of the fins are lighter.

The appearance of grass carp is very similar to that of herring, but the body color of the two is different. The body color of grass carp is brown and gray, and the even fin is grayish-yellow, while the body color of the herring is blue-black, and the even fin is even more blue and black against the white belly. X0d X0a grass carp is widely distributed, except for Xinjiang and the Qinghai-Tibet Plateau, which has no natural distribution, and is distributed in all major river systems in China.

x0d x0a grass carp generally inhabits the middle and lower layers, and sometimes feeds in the upper layers. Sexually active and fast swimmer. Herbivorous, plankton-dominated during the fish period, juveniles also feed on aquatic insects.

Juveniles with a body length of more than 50 mm. gradual transition to herbivorous; With a body length of about 100 mm, it is fully adapted to feed on aquatic higher plants. Adults mainly feed on higher aquatic plants, such as bitter grass, black algae, small algae, eyeweed, duckweed, and turnip are the most popular food species. Flooded grassy areas are often fattening grounds for grass carp, and some dry grasses are also preferred by grass carp.

The reproductive population of x0d x0a grass carp is mainly 4 5 years old, mainly individuals with a body length of 650 850 mm and a weight of 4 9 kg. The smallest female is 4 years old, with a body length of about 540 mm and a weight of about kilograms; Males are 3 years old, with a body length of about 550 mm and a system of about kilograms. The reproductive season is from early May to early June, with peak season in mid to late May.

The naked belly sturgeon, also known as the "sturgeon yellow croaker", is an endemic fish species of the Ili River.
