Is herring a freshwater fish or a marine fish? Introduction to herring

Fish are generally divided into two categories. One is the fish that grow in rivers and lakes, which we call freshwater fish, and the other is the fish that grow in Hanzhong, also called marine fish. So, is black carp a freshwater fish or a marine fish? Is black carp a grass carp?

Is herring a freshwater fish or a marine fish?

There are two types of black carp:

1. One is freshwater, which is known as one of the four major farmed fish in China along with grass carp, silver carp and bighead carp;

2. Another kind of black carp is scientifically called herring, which is a marine fish.

Characteristics of black carp

1. Black carp is also called black carp and snail carp. It belongs to the class of bony fishes, family of Cyprinidae.

2. The body is subcylindrical, up to 1 meter long. It is bluish black with grayish black fins.

3. The head is broad and flat, the mouth is terminal, and there are no whiskers. The pharyngeal teeth are molar-shaped.

4. They live in the middle and lower layers, and feed mainly on snails, clams, shrimps and aquatic insects. They reach sexual maturity at 4-5 years old, lay eggs in the upper reaches of rivers, and can be artificially bred.

5. The fish is large and grows fast, with the largest fish weighing 70kg. The meat is delicious. It is the main freshwater fish for breeding in China. It is distributed in major water systems in China, and is mainly produced in the plains south of the Yangtze River.

Origin of Chinese black carp

Black carp is a green fish that is mainly distributed in the plains south of the Yangtze River in my country and is relatively rare in the north of the Yangtze River. It is an important fishery resource in the middle and lower reaches of the Yangtze River and the lakes along the river, and the main breeding object in lakes and ponds. It is one of the "four major carps" in my country's freshwater farming.

In addition, in Anhui, it is commonly known as "Wuhun", "Heihun" or "Luoshihun", named because of its black body and love of eating snails; the "black carp" commonly seen in the Northeast is not black carp, but should be written as "mackerel", a deep-sea fish. In China, the largest black carp specimen weighed 218 kilograms and was caught in Jinniu Lake, Liuhe District, Nanjing in 2005. It was 1.86 meters long and weighed 218 kilograms. According to scale identification, it was about 40 years old.

Nutritional analysis of black carp

In addition to 19.5% protein and 5.2% fat, black carp also contains calcium, phosphorus, iron, B1, B2 and trace element zinc. Adults need 12 to 16 grams of zinc per day, and the amount required during adolescence increases accordingly. Zinc is an important component of enzyme protein, and is closely related to the gonads, pancreas and cerebrospinal fluid. The zinc content in the human body is only 0.3%, but once it is insufficient, it often causes a decrease in sense of smell, mental depression, and a decrease in "IQ (an index to measure intelligence)". In addition, there will be lesions such as insufficient growth height and difficulty in healing wounds.

Is herring a marine fish or a freshwater fish?

Question 1: Is herring a marine fish or a freshwater fish? Freshwater fish, called black herring in the south, grows fast and can weigh up to 40 kilograms

Question 2: Is herring a deep-sea fish or a shallow-sea fish? Herring is neither a deep-sea fish nor a shallow-sea fish. It is a freshwater fish. Herring is a green fish that is mainly distributed in the plains south of the Yangtze River in my country and is relatively rare in the north of the Yangtze River. It is an important fishery resource in the middle and lower reaches of the Yangtze River and the lakes along the river, and the main breeding target in various lakes and ponds. It is one of the "four major fishes" for freshwater breeding in my country. Herring is also called black carp and snail green. It belongs to the class of bony fish, the family of Cyprinidae. It has a subcylindrical body and can be up to 1m long. It is blue-black in color, and its fins are gray-black. It has a wide and flat head, a terminal mouth, and no whiskers. Its pharyngeal teeth are molar-shaped. It lives in the middle and lower layers, and its main food is snails, clams, shrimps, and aquatic insects. It reaches sexual maturity at 4-5 years old, spawns in the upper reaches of the river, and can be artificially bred. It is large and grows rapidly, with the largest individual reaching 70kg. It has delicious meat. It is the main freshwater fish breeding target in China. It is distributed in major water systems in China, and is mainly produced in the plains south of the Yangtze River.

Question 3: Is black carp a marine fish? Black carp is one of the most common and unique freshwater farmed fish in my country.

You can buy marine fish (such as hairtail, yellow croaker, etc.) in general vegetable markets.

Question 4: Is the giant grouper a marine fish or a freshwater fish? The giant grouper is a marine fish.

Long grouper (lóng dǔn), scientifically known as giant grouper, also known as pig lamb grouper, is a warm-water marine bottom fish.

It is long and oval, flattened on the sides, with a large mouth. There are many dark blue spots on the head, sides and fins of the fish. It is a large and precious edible fish. In natural waters, adult fish are generally 60 cm to 70 cm long, and the maximum body length can reach 2 meters. The weight is generally around 30 kg to 40 kg, and the larger ones can reach 100 kg to 160 kg or more.

Question 5: How do you distinguish between marine fish and freshwater fish? To distinguish between marine fish and freshwater fish (river fish), you need to compare them from several aspects:

1: The overall nutritional value of marine fish and river fish is roughly the same:

The biggest difference between river fish and sea fish is their growth environment.

In fact, strictly speaking, river fish should be called freshwater fish. Common ones include carp, crucian carp, grass carp, silver carp, Wuchang fish, tilapia, eel, etc.; sea fish include hairtail, tuna, large yellow croaker, small yellow croaker, mackerel, salmon and turbot, etc.

Whether it is freshwater fish or marine fish, the nutritional components are roughly the same, and the overall nutritional value is very high. First, fish meat is rich in protein, and the amount and ratio of essential amino acids contained in it are most suitable for human needs. Therefore, it is a good source of protein for humans. Secondly, fish meat has a low fat content and is mostly composed of unsaturated fatty acids. The human body absorption rate can reach 95%, which has the effect of lowering cholesterol and preventing cardiovascular and cerebrovascular diseases. Third, fish meat is rich in minerals, such as iron, phosphorus, calcium, etc.; fish liver contains a lot of vitamin A and vitamin D.

In addition, fish meat has short muscle fibers and a high water content, so the meat is tender and easier to absorb than livestock and poultry meat. Compared with foods that are highly nutritious but difficult to absorb, fish meat is more beneficial to people's health.

2. Marine fish is slightly better in nutrition and taste:

The fact that the nutritional ingredients are similar does not mean that the nutritional value of the two is exactly the same. Marine fish has more nutrients than river fish and has a slightly better nutritional value.

The sea is extremely rich in nutrients, especially a large amount of nutrient salts, which makes the mineral and vitamin content in marine fish higher. In addition, the liver oil and body oil of marine fish contain a highly unsaturated fatty acid that is not found in animals and plants on land. It contains a component called DHA (commonly known as brain gold), which is a nutrient necessary for the brain and is very important for improving memory and thinking ability. In addition, the content of omega-3 fatty acids and taurine in marine fish is much higher than that in freshwater fish, which has a protective effect on the heart and brain.

In terms of taste, sea fish tastes fresher than river fish. This is because sea fish have a larger swimming range and greater strength than river fish, which makes their muscles more elastic and delicious. River fish tastes earthy because they grow in water with more humus. Such an environment is suitable for the reproduction and growth of actinomycetes. The bacteria invade the fish's blood through the gills and secrete a brown substance with an earthy smell, which is difficult to remove during cooking.

3. River fish has an inherent earthy smell:

When it comes to eating fish, steaming, braising and other methods are more suitable.

Among river fish, crucian carp has a long growth period, soft meat and high nutritional value, making it suitable for the elderly, children and pregnant women. However, it is difficult to cover up the earthy smell of some freshwater fish such as carp and silver carp when steamed, and the taste is far worse than that of marine fish.

It is best to eat marine fish cooked. Eating it raw will cause severe abdominal pain and allergies due to Anisakis infection. When eating freshwater fish, you must check whether it is caught from polluted water. Contaminated fish contain toxins that can be harmful to your health.

4. Types of marine fish:

Marine fish can be divided into naturally grown and artificially cultivated ones.

Some marine fish cannot be artificially cultivated. For example, among the common marine fish on the market, those that cannot be artificially cultivated include hairtail, horse mackerel, pomfret, yellow croaker, sardines, boss fish, small yellow croaker, etc. Squid and cuttlefish also cannot be artificially cultivated.

Sea bass, black skirt, large yellow croaker, six-line fish, crab, jellyfish and other seafood are both caught and farmed;

Basically all of the fish that are artificially cultivated include the Japanese flounder, the big yellow flounder, the turbot, and the semi-smooth tongue flounder.

5. Types of freshwater fish (river fish)

In our daily life, the most famous freshwater fish we often eat are the four major carps: carp, silver carp, grass carp and black carp.

In addition, there are eels, turtles, etc.

Of course, there are many other species of river fish.

Question 6: Are there black carps among marine fish? There are two types of black carps. One is freshwater and is known as one of the four major farmed fishes in China along with grass carp, silver carp and bighead carp. The other black carp is scientifically called herring and is a marine fish.

Question 7: How to distinguish the nutritional value of marine fish and freshwater fish? The nutritional value of fish meat

Fish meat has high overall nutritional value. As the name implies, the biggest difference between river fish and sea fish is their growth environment. In fact, strictly speaking, river fish should be called freshwater fish, and common ones include carp, crucian carp, grass carp, silver carp, Wuchang fish, tilapia, eel, etc.; sea fish include hairtail, tuna, large yellow croaker, small yellow croaker, Spanish mackerel, salmon and turbot, etc.

Whether it is freshwater fish or marine fish, the nutritional components are roughly the same, and the overall nutritional value is very high. First, fish meat is rich in protein, and the amount and ratio of essential amino acids contained in it are most suitable for human needs. Therefore, it is a good source of protein for humans. Secondly, fish meat has a low fat content and is mostly composed of unsaturated fatty acids. The human body absorption rate can reach 95%, which has the effect of lowering cholesterol and preventing cardiovascular and cerebrovascular diseases. Third, fish meat is rich in minerals, such as iron, phosphorus, calcium, etc.; fish liver contains a lot of vitamin A and vitamin D.

In addition, fish meat has short muscle fibers and a high water content, so the meat is tender and easier to absorb than livestock and poultry meat. Compared with foods that are highly nutritious but difficult to absorb, fish meat is more beneficial to people's health.

Marine fish contain nutrients essential for the brain

Common marine fish include hairtail, yellow croaker, abalone, squid, sardines, pomfret, Spanish mackerel, tuna, salmon, etc. According to experts, the liver oil and body oil of marine fish contain a highly unsaturated fatty acid that is not found in terrestrial animals and plants. Among them, there is a component called DHA, which is a nutrient necessary for the brain. It can be said that DHA is very important for improving people's memory and thinking ability from the fetus, through infants and young children to teenagers, and even throughout the entire life process of human activities.

In addition, the omega D3 fatty acids and taurine in marine fish are much higher than those in freshwater fish. Studies have found that omega D3 fatty acids have a good effect on relieving cerebral vasospasm and malignant migraine, and can also improve the body's anti-inflammatory ability.

Marine fish is slightly better in nutrition and taste

The fact that the nutritional ingredients are similar does not mean that the nutritional value of the two is exactly the same. Marine fish has more nutrients than river fish and has a slightly better nutritional value.

The sea is extremely rich in nutrients, especially a large amount of nutrient salts, which makes the mineral and vitamin content in marine fish higher. In addition, the liver oil and body oil of marine fish contain a highly unsaturated fatty acid that is not found in animals and plants on land. It contains a component called DHA (commonly known as brain gold), which is a nutrient necessary for the brain and is very important for improving memory and thinking ability.

In terms of taste, sea fish tastes fresher than river fish. This is because sea fish have a larger swimming range and greater strength than river fish, which makes their muscles more elastic and delicious. River fish tastes earthy because they grow in water with more humus. Such an environment is suitable for the reproduction and growth of actinomycetes. The bacteria invade the fish's blood through the gills and secrete a brown substance with an earthy smell, which is difficult to remove during cooking.

Steamed river fish has an earthy smell

Speaking of eating fish, sea fish is suitable for people of all ages, and can be steamed or braised. Among river fish, crucian carp has a long growth period, soft meat and high nutritional value, making it suitable for the elderly, children and pregnant women. However, it is difficult to cover up the earthy smell of some freshwater fish such as carp and silver carp when steamed, and the taste is far worse than that of sea fish.

It is best to eat marine fish cooked. Eating it raw will cause severe abdominal pain and allergies due to Anisakis infection. When eating freshwater fish, you must check whether it is caught from polluted water. Contaminated fish contain toxins that can be harmful to your health.

Carp soup can cure cough

Freshwater fish mainly include carp, grass carp, crucian carp, black carp, eel, silver carp (fathead carp), etc. According to experts, freshwater fish are rich in nutrients such as protein, vitamin A, D and various minerals.

Carp has the functions of strengthening the spleen and appetizing, promoting diuresis and reducing swelling, relieving cough and relieving asthma, calming the fetus and promoting lactation, clearing away heat and detoxifying. Carp, winter melon and scallion are boiled in soup to treat edema caused by nephritis. Large carp with scales removed and intestines stewed and cooked can treat jaundice. Live carp and pig's trotters are boiled in soup to treat insufficient milk in postpartum women. Carp and a little Sichuan Fritillaria powder are boiled in soup to treat cough and asthma.

Grass carp meat is sweet and warm in nature. It is steamed with fried dough sticks, eggs and pepper powder to improve eyesight. Grass carp also has the functions of warming the stomach and calming the liver, making it suitable for the elderly to nourish and keep fit.

Crucian carp is suitable for patients with edema caused by chronic nephritis and liver cirrhosis. You can use 1 fresh crucian carp (about 250 grams) and winter...>>

Question 8: The difference between deep-sea fish and freshwater fish The biggest difference between river fish and sea fish is their growth environment. River fish should be called freshwater fish, and common ones include carp, crucian carp, grass carp, silver carp, Wuchang fish, tilapia, eel, etc.; sea fish include hairtail, tuna, large yellow croaker, small yellow croaker, Spanish mackerel, salmon and turbot, etc. Whether it is freshwater fish or sea fish, their nutritional components are roughly the same, and the overall nutritional value is very high. Sea fish is best eaten cooked, and eating raw will cause severe abdominal pain and allergies due to Anisakis infection; eating freshwater fish depends on whether it is fished from polluted water. Polluted fish contains toxins and can cause harm to health. The content of ingredients is higher than that of river fish, and the nutritional value is slightly better.
