How to distinguish silver carp and carp in the vegetable market from farmed or wild?

Silver carp mainly refers to freshwater silver carp and bighead carp (also known as silver carp). Almost all silver carp are mainly filter-feeding mayfly organisms, among which silver carp mainly filter-feed mayfly plants such as algae, and its gill rakers are relatively dense; The tarpon mainly filter-feeds mayflies, and its gill raker structure is loose.

Therefore, from the perspective of eating habits, there is not much difference between artificially bred silver carp and wild silver carp that do not eat feed. Comparatively speaking, farmed water bodies tend to be fatter, and bighead carp grow faster, but taste similar to wild.

Carp is an omnivorous fish, mainly feeding on aquatic plants, organic matter, organic detritus, etc. under natural conditions, and its growth rate is relatively slow, usually 2-3 years to grow to about 1 catty of market specifications. Artificial breeding is usually fed with feed, the growth rate is fast, and the fry can be marketed in about 1 year after being put into the pond. Of course, farmed carp taste much worse than wild carp.

It is mainly manifested in the loose meat quality, earthy smell, and the fish is very fatty and has a high fat content.

We can't distinguish the difference in taste when buying from the vegetable market, so how can we judge it from the appearance?

1.The bait of carp in natural waters is far less abundant than in artificial ponds, so carp in the wild are often not very fat, and the fish are slender and thin. Wild fish often eat small fish and shrimp for food, often have to parade in many places to eat, and sometimes even starve, the belly is very flat and thin.

And the farmed ones are not short of food, and the belly is bulging, a bit like a "beer belly." Easy to identify.

2.Carp in the wild have a long growth cycle and long-term natural water conditions that make their body color more vibrant. Therefore, most of the people with blue and yellow body color are wild, and most of the white and glossy ones are farmed.

3.The tail of wild carp is mostly red, and so are its fins, and most of the fish farmed by users are white, which is very different.

4.The farmed fish basically grow up eating feed, and the excrement is mostly black and has a strong fishy smell. And wild excrement is very little to talk about.

The last one is to eat, the wild carp is delicious and chewy, especially the soup is fragrant. The farmed fish soup tastes like carrion, and it melts in your mouth.

5.Wild fish snouts are sturdy and worn, and farmed fish are generally white and clean.

Crucian carp has a little experience, but it is not very accurate, it can only be used as a reference: 1. There is a difference between wild crucian carp and crucian carp in the fish pond is the body type, the height of the wild crucian carp head is not much lower than the height of the back to the stomach, it is basically a shuttle type, and the crucian carp raised in the fish pond has a small head and a high back. 2. In the same case, wild crucian carp are more active than crucian carp raised in fish ponds, and are more likely to react violently after being frightened.

Roughly these two methods. I've tried everything else to be fat and thin, and I've tried all the body color, but I'm not allowed.

At present, in the market, artificially cultivated seafood still occupies the main fresh market, the reason is that the overfishing of human beings has led to the reduction of wild seafood resources, and the second is the progress of breeding technology. However, with the rapid development of quick-freezing technology and the development and popularization of cold chain logistics in recent years, the space and time problems from the sea to the table, which were difficult to overcome in the past, have now been reduced to 24 hours in most parts of the country, and the freshness can be guaranteed enough. Once it becomes popular, it is believed that wild seafood will appear more and more on people's tables.

The selection of this fish in the vegetable market is mainly judged by its size, whether it is wild or farmed, and the wild is slender and long, with firm flesh and uniform body shape. The cultivated body is stout, with more fish oil in the body, and the meat is relatively loose and swaying.

When buying fish, you can distinguish whether it is wild fish or imported farmed fish from the color, shape, body shape and size of the fish. First of all, the body color of the fish, the body color of wild fish is white, and the body color of farmed fish is black and dark; Wild fish are fry, narrow, and have inconspicuous lateral lines between the back and belly; The farmed fish are fat, broad, and have a clear lateral line; Wild fish are of different sizes, mixed with varieties such as plate yellow and Sichuan clove, and the size of the farmed fish is uniform and the internal organs are large. By mastering these methods, the public can distinguish the difference between the two types of fish with the naked eye, making it easier to buy.

I think the main thing to distinguish them from is to look at the gills and fins and other obvious signs.

I feel that if it is a wild fish, the probability is more lively.

Wild fish meat is tender and chewy, whether it is wild or not, you can distinguish it once you buy it, and you can avoid it next time.

In fact, it can be distinguished by the quality of the meat and the activity of the fish.

You can look at the vitality of these fish, wild fish are relatively energetic.

Look at the meat quality of the fish, the flesh of wild fish should be more elastic and will taste better.

I think you can see by looking at the belly that the farmed fish have a larger belly, and the wild fish are thinner.

Silver carp and carp in the market can be accurately identified by the color of the scales.

The scale arrangement of silver carp is different, and there must be a little difference in length, otherwise how to know.

I don't think you can see it by looking at it, you need to taste it to be able to distinguish it.
