Threatened lake sturgeons appear on the spawning grounds in St. Lawrence. I descend into their midst each year to document their numbers and behaviour. Three decades-long conservation efforts here have been successful and this population is finally winning but others are not. Sturgeon survived the mass extinctions that killed the dinosaurs, they may not survive mankind. Demand for caviar and hydropower have erased these giants from the depths.
