It is normal for river fish to smell earthy. Generally, in China, river fish are killed and eaten now, which can reduce the earthy smell, so frozen river fish are basically not eaten. In order to prevent and control Asian carp, the United States simply does not allow live transportation. Asian carp killed in advance, all the way to the factory and then to the supermarket, must be unpalatable.
Moreover, these Asian carp have a long growth period, are large and have a heavier earthy smell. American cooking doesn't need any heavy ingredients, and simply frying it is definitely not delicious. It is unrealistic to transport the frozen Asian carp flooded in the United States to China for sale. We pay attention to the freshness of fish. Even if you fly in chilled, nobody will buy it, no matter how cheap it is.
Some people say that European hairy crabs are rampant, while China hairy crabs are ridiculously expensive. Isn't it killing two birds with one stone to sell it to us? Why not import hairy crabs? Actually, it's not that simple to want a bite of European hairy crabs.
Take Germany as an example. Without quarantine certificate, hairy crabs can't pass the customs at all. However, Germany is extremely strict in this respect and it is difficult to pass smoothly. Even if you settle in Germany, you can't enter China Customs. The reason is easy to understand. Hairy crabs must be bought alive, but as long as they are alive, they will definitely carry exotic species, which is very alarming.
Moreover, even if the transportation time is saved, the process of customs quarantine will have to wait at least three or four days, and it will take a few days to get it to consumers. Can this crab stand all these troubles? Dead crabs must not be eaten! Therefore, we cannot eat imported hairy crabs. If we want to eat them, we must go abroad
If imported blindly, it will also bring the danger of alien species invasion and cause ecological disaster.
