B.C. clams reveal an ancient secret (with video)
First Nations “clam gardens” dramatically increase the survival, growth rate and size of shellfish using materials as simple as boulders and crushed shells, according to a new study by researchers at Simon Fraser University and the University of Washington.
A collaborative project by marine ecologists and archeologists studied clam growth in ancient stone-walled beach terraces created over the last few thousand years. The team recorded four times as many butter clams and twice as many littlenecks in clam gardens compared with unaltered beaches.
