Among the many practices of perch, steaming perch is the most classic. Simply steaming it can completely retain the nutrients and umami taste of the fish, with less nutrient loss. I believe many friends also like to eat it. But when friends buy bass, remember to distinguish between sea bass and freshwater bass. The difference between seawater and fresh water is mainly due to the different waters and environments in which they grow. Although they are both perch, there is still a big difference in taste and nutritional value between them. Today, I will share with you the difference between sea bass and fresh water bass. After learning how to distinguish them, don't buy them wrong again.
Sea bass VS freshwater bass
1, different appearance
Although the two kinds of perch are similar in appearance, they are still different in appearance. Living in the sea, the sea bass is larger than the freshwater river bass, showing that the fish body is thick and long, the scales are rough, the color is generally divided into white or black, and there are many black spots scattered on the fish body. The freshwater perch is relatively small in size, and its scales are relatively small, and its color is mostly silvery white or yellowish.
2, the taste is different
In terms of taste, the meat quality of sea bass is relatively firewood, not as tender as that of fresh water bass, and because sea bass lives in the sea, the smell of sea bass is stronger than that of fresh water bass. Relatively speaking, the meat quality of freshwater perch is more tender, and the fishy smell is not heavy. Especially when steaming perch, I suggest you buy freshwater perch. After steaming, the fish is easy to spread out, just like the "garlic clove meat" we often describe, and it has no fishy smell in seawater, and the meat tastes light, sweet and delicious.
3. Different nutritional values
These two kinds of sea bass are very rich in nutrients, but compared with freshwater bass, sea bass has better fat structure, higher contents of unsaturated fatty acids and protein, and higher contents of trace elements, which are beneficial to the health, especially for the elderly and children. Therefore, the nutrients of sea bass are higher than those of fresh water bass.
The above is the difference between sea bass and freshwater bass that I want to share with you today. When buying sea bass, we should also distinguish the freshness of sea bass from the following three points.
How to choose fresh perch
First, look at the fish eye
First of all, we should observe the eyes of perch. The eyes of fresh perch are clear, transparent, not turbid, full and protruding, without red tendons. However, if the bass' eyes are turbid and hazy, it means that the fish has been placed for some time and is no longer fresh.
Second, look at the fish belly
We also need to observe the belly of the perch. Under normal circumstances, the belly of the perch is relatively flat. If the belly of the perch looks particularly bloated, it seems that it has eaten a lot of food. This perch should be purchased with caution, which may be caused by the traders pouring feed into it in order to increase the weight of the fish.
Third, look at the fish tail
The bass tail is a fragile part of the fish, and the normal bass tail is black and slightly transparent. When the bass is injured, it will react at the tail first, making the tail red, and it is also easy to cause bacterial infection. Like the bass with red tail, it can't be bought at any price.
