The difference between silver carp and bighead carp

Difference 1: Different appearance features

Silver carp has a flat body, thick flesh, an extremely large head, a large mouth, small eyes, and no whiskers. 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 is flattened and hammer-shaped, and its flesh is not as thick as that of bighead carp. Its back is blue-gray, and its sides and belly are white. Its head is much smaller than that of silver carp, and its eyes are located lower.

Difference 2: Different prices

The price of silver carp has always been around 3-4 yuan per catty, while bighead carp is half as expensive as silver carp. The reason is that the head of bighead carp is valuable. The essence of bighead carp lies in the head, which is rich in phospholipids and posterior pituitary hormone. Eating it regularly has many benefits. Therefore, silver carp is often sold as a whole in the market, while bighead carp is sold in grades. If you only buy the head of bighead carp, the unit price is about 10-12 yuan per catty.

Difference 3: Different ways of eating

As we all know, silver carp usually live in the upper layer of the water, often eat phytoplankton such as green algae, have a tough texture, and have many small bones. In addition, silver carp is easy to die after being taken out of the water, and it is not easy to keep fresh. It spoils very quickly, and has a strong fishy smell (the freshness of fish mainly comes from trimethylamine oxide in the body. After the fish dies, trimethylamine oxide will continue to be reduced to trimethylamine with fishy smell, which makes the fish smell fishy. The longer the fish has been dead, the stronger the fishy smell). In our area, the common way to cook silver carp is to make crispy fish. The whole fish is put into the dish, and vinegar, sugar and other seasonings are added to slowly crisp it for 4-5 hours. When eating, you can eat it with the bones.

There are many dishes made from silver carp after they are graded, such as the classic dishes of Jiangsu and Zhejiang cuisine, such as "braised fish head" and "Tianmu Lake fish head stew", and the classic Hunan cuisine, "chopped pepper fish head". The fish body is relatively cheap, and it is usually cut into pieces for frying, deep-frying, and stewing to make fish soup, or making fish meatballs and dumplings.

Tips for removing fishy smell from silver carp and bighead carp

Whether you use white sweet potato to bury silver carp or bighead carp to make dishes, removing the fishy smell is definitely the first priority. Many friends will add salt and cooking wine to marinate fish meat, but I think the effect is not obvious. I recommend two techniques to remove the fishy smell.

1. Use white vinegar to remove fishy smell: When marinating fish, add a little white vinegar and marinate for a dozen minutes to remove the fishy smell. Generally, 50 grams of white vinegar is needed for about 1 kg of fish.

2. Use pepper water to remove the fishy smell: add water to the pot, put in peppercorns, green onion and ginger slices, etc., boil until fragrant and let cool. Then put the fish in and soak for about half an hour to achieve the purpose of removing the fishy smell.

Final Thoughts

There is still a big difference between silver carp and bighead carp, especially from the size of the head and the color of the body, they can be easily distinguished. If you are interested, you can also go to the market to buy two fish for comparison.

1. The difference in color. The whole body of silver carp is dark blue, while that of bighead carp is mainly silver gray. 2. The size of the fish head. The head of silver carp accounts for one-third or even one-half of the whole body. It is also called fathead fish. The head of silver carp only accounts for one-quarter of the body. 3. The difference in price. Silver carp is more expensive than silver carp.

Silver carp is white and flat, with its head accounting for one third of its body. It has white prismatic scales and a distinct crease under its belly. It has many small spines, which is related to its jumping in the water. The fish meat is loose and not as tender as silver carp.

Silver carp is commonly eaten in rural areas. It tastes delicious when cooked, but silver carp has a lot of bone spurs. Bighead carp is different. It tastes delicious, the meat is relatively delicate, and the bones are less and more neutral.

It seems that city people don't eat it.
