Armed with traditional knowledge and modern science, a small team hunts for the sweet spot that could save oysters from a parasite that has decimated populations in Cape Breton and beyond.
The dead oyster falls from the plastic mesh bag with the hollow clop  of a horse hoof on pavement. Its shell gapes, innards rotted. About 100  or more oysters—some living, some dead—quickly follow, clattering like  maracas onto the flattened bow of Joe Googoo’s dark-green jon boat. Clad  in a jacket with blaze-orange sleeves and a ball cap with a moose on  it, Googoo pulls a knife from his belt holster in one smooth motion and  taps oyster shells with its curved tip as he sorts through the mottled  pile. Counting them one by one, he tosses lifeless shells aside and puts  the living oysters back in the bag.
Beside Googoo, Robin Stuart, a large, curly-haired man in a tattered  black-and-blue drysuit, perches on the boat’s edge. Stuart, one of Nova  Scotia’s most experienced aquaculture experts, cracks jokes as he, too,  picks around for “morts”—mortalities. “If you could grow an oyster big  enough, Joe would be buried in it,” he says with a chuckle. As the  longtime friends tally the dead, Stuart soon grows somber. “There’s  almost as many morts as there are live,” he says in his gravelly  Scottish-Welsh brogue. “MSX is definitely doing its thing here.”
