The sea lamprey is native to the Atlantic Ocean, which means it would be spawning on both the American side and the European side. Actually, I think Mr. Allen brought up the issue that two lampreys were sent to the Queen. I guess China goes with pandas and we go with sea lamprey, no pun intended.
The interesting thing is that, for example, in Portugal--for which I have factual information, because one of my colleagues is the terrestrial invasive species chair at Algoma and he is from Portugal--the sea lamprey is literally a national delicacy. They eat arroz de lampreia, which is a dish prepared out of rice and lamprey blood.
Yes, I'm from Transylvania. Both things are true.
There is a fishery—at least it used to be a commercial fishery for sea lamprey—and it's at the point of being overfished in the Atlantic Ocean. At the present time it's such a highly sought after food item that you could get 50 to 80 euros per live lamprey in Portugal: there are not enough of them. Yet here, of course, it's invasive, and it's very difficult to control and probably impossible to eradicate.
