What are these delicious scallops doing here?
They are growing in a Scottish loch next to salmon farms.
Until recently, no scallops were harvested here.
But it turns out that scallops, as well as mussels, oysters or sea urchins love the nutrients left over by farmed fish.
This new aquaculture technique is said to be more ecological, efficient and profitable than traditional methods.
And it is being currently tested in seven pilot sites across European waters.
