Is there any difference between Baotou fish and Hualien fish?

In fact, there is no difference between them! They are all fish! There are differences! Baotou fish, also known as fathead fish by locals, should be a genuine local specialty, with strong bones and muscles, and authentic wild Baotou fish!

Hualien fish name: Hualien fish Silver carp belongs to the Cypriniformes order,

Silver carp has a flat body and an extremely enlarged head. The mouth is large and terminal, with the lower jaw tilted slightly upward. The gill rakers are dense and leaf-shaped, but not fused with segments. There are spiral-shaped supragranial organs in the upper part of the oral and pharyngeal cavity, small eyes, low position, no whiskers, and spoon-shaped pharyngeal teeth with smooth tooth surfaces. The scales are small, and only the pelvic fins and even the anus have cortical ventral ridges on the ventral surface. The pectoral fins are long, and the ends are far beyond the base of the pelvic fins. The upper half of the body is gray-black, the abdomen is gray-white, and there are many irregular small spots of light yellow and black on both sides.

Silver carp likes to live in the middle and upper layers of still water. It moves slowly and doesn't like to jump. It feeds mainly on zooplankton and also eats some algae. Sexual maturity is at the age of 4-5 years. Parent fish breed in the river section with rapid currents and whirlpools from May to July when the water temperature is 20-27℃. Juvenile fish generally grow fat in lakes and affiliated water bodies along the river. When they reach sexual maturity, they breed in the river and then return to the lake where food is abundant to grow fat. In winter, they mostly live in riverbeds and deep rock pits to hibernate.

Distributed in eastern Asia, this fish can be found in all major water systems in my country, but the middle and lower reaches of the Yangtze River are the main production areas.

Silver carp grows rapidly, with a 3-year-old fish weighing 4-5 kg ​​and a maximum individual weighing 40 kg. It has a high natural yield, is disease-free and easy to raise. It is one of the "four major carps" in my country's freshwater aquaculture industry and an important economic fish in my country.

The nutritional components of silver carp muscle are as follows: 73.2-83.3 grams of water, 14.8-18.5 grams of protein, 0.9-7.8 grams of fat, 1.0-1.3 grams of ash, 0.1-1.3 grams of nitrogen-free extract, 69 kcal of calories, 36 mg of calcium, 187 mg of phosphorus, 0.6-1.1 mg of iron, 0.02 mg of thiamine, 0.15 mg of riboflavin, and 2.7 mg of niacin per 100 grams of edible part. Moreover, as the fish grows and develops, the water content gradually decreases, while the protein and fat content gradually increases. The difference in fat content between bighead carp and silver carp is mainly due to different food. Silver carp and bighead carp are both filter-feeding plankton, but silver carp mainly feeds on phytoplankton, while bighead carp mainly feeds on zooplankton. Phytoplankton contains a large amount of carbohydrates, which is the main carbon source for fish to synthesize fat, so the fat and protein content of their muscles are different. Silver carp has a higher fat content than bighead carp, while bighead carp generally has a higher protein content than silver carp. There are 15 types of fatty acids in bighead carp muscle fat, including 8 saturated acids, 3 monoenoic acids, 1 dienoic acid, 2 trienoic acids, and 1 tetraenoic acid, with a carbon chain length between 13 and 20. The percentage of saturated fatty acids in fish is lower than that of unsaturated fatty acids, and the content of saturated fatty acids increases with the growth of the fish body, while the content of unsaturated acids decreases with the growth of the fish body.

The essence of silver carp lies in its head. Nie Weiping, who is praised as a "top-notch chess player" by the Japanese chess community, loves to eat fish heads and can eat 5 or 6 in one meal. This is not only because they are delicious, but also because he believes that fish heads can nourish the brain. Bighead carp meat is sweet and warm in nature, and has the effect of warming the stomach and strengthening the tendons and bones. Fish heads can be used as medicine to treat rheumatic headaches and dizziness in women. Its gallbladder is bitter, cold and poisonous. It has a short-term antihypertensive effect when injected intravenously; increasing the dose will have a long-lasting effect. Because bighead carp gall is poisonous, the effective antihypertensive dose is very close to the toxic dose, so it needs to be used clinically with caution. Poisoning can also occur if fish gall is swallowed, and the symptoms are the same as those of grass carp gall and carp gall. There is currently no special treatment, so attention should be paid; if it is not necessary, it is not advisable to take fish gall indiscriminately to avoid poisoning

What kind of fish is this?

Judging from the photo, you have a silver carp, also known as a bighead carp.

Silver carp pictures:

Silver carp belongs to the bighead carp, and bighead carp belongs to the bighead carp. They are both freshwater fish in the carp family.

Silver carp and bighead carp can be distinguished by their appearance:

Head: Silver carp, also known as fathead fish, has a large head, which is equivalent to 1/3 of its body length. Its head is relatively round, and its mouth is also very large, with its upper jaw slightly protruding forward. The bighead carp has a small and somewhat flat head, which is equivalent to 1/4 of its body length. Its mouth is very small, and its lower jaw slightly protrudes forward.

Body color: The back of the bighead carp is dark brown, with fine black spots on the back, and some grayish white mixed in between. The abdomen is grayish white, and all the fins are light gray; the back of the silver carp is silvery white, the abdomen is bright white, and all the fins are grayish white. Pectoral fins: The pectoral fins of the bighead carp are larger, much larger than the base of the pelvic fins; the pectoral fins of the silver carp are smaller, and the tip of the pectoral fins only reaches the base of the pelvic fins. Abdominal ridge: The abdominal ridge of the bighead carp is from the pelvic fin to the anus, the abdominal ridge is shorter, and the area between the head and the pectoral fin is smooth and without edges; the abdominal ridge of the silver carp is from the chest to the anus, the abdominal ridge is longer, and the edges are clear.

Silver carp has firmer meat and fewer burrs, while bighead carp has looser meat and more burrs. Silver carp has a better taste and higher nutritional value than bighead carp. So it is slightly more expensive.

This should be Hualien Huaixian, we usually call it fathead fish or bighead carp. This fish is much more delicious than the white lotus. The white lotus is not so thick, the head and body are not so thick, it is thinner, and generally not so big, and it is still white.

This fish has a big mouth, black patterns on its back, long ridges and long fins. It is a silver carp.
