Scientists find that using oysters as water filters helps the bivalve and other species thrive – and could treble the amount of carbon going into the seabed
Good whisky needs pure clean water, which partly explains why distilleries in Scotland always seem to have such scenic, loch-side backdrops. And one of the best ways to filter that water is oysters. Indeed, the European native oyster was so plentiful in Scotland that 30 million a year were harvested from oyster beds outside Edinburgh in the 1800s.
But today the species is almost extinct: populations have dropped by 85% over the past century, most likely because of overfishing from bottom trawling.
