The problem is lack of demand for this particular oyster in Europe. Otherwise this would be considered a boon for local fisherman. The oysters the article is referring to are of the "giant" variety with many of them being about the size of a human hand (fingers and all).

Not having eaten them myself, I would guess the taste isn't quite the same as their smaller cousins served over ice on the half shell. Also, even if they did taste similar, the sheer size would likely make them unappetizing to even the most adventurous westerners.

The Chinese on the other hand are very familiar with the giant pacific variety and have many traditional recipes for them.
