Why are the locals unhappy about the proliferation of Danish oysters?

From some reports, we can know that Danish oysters have been flooded, which is a boon for the vast number of China gourmets, and there are various concerns on the Internet, but why can't Danish locals be happy?

In fact, this should start with this oyster. Danes also like oysters very much. However, this disaster-stricken oyster is an exotic species, from the Pacific Ocean, not native to Denmark. This will make the local people feel a sense of fear, especially when they see a piece of pressed shore. How dare they eat?

Furthermore, Denmark is a comfortable transition. They are used to their oysters. They can say that they know nothing about this invaded oyster and don't know how high the safety factor is. They dare not fish blindly. Moreover, the massive reproduction of oysters has also caused a kind of harm to them, making local people tired of seeing this oyster on the beach.
