Pacific Northwest oyster hatchery crisis (2007-2009)
Ocean acidification, driven by carbon dioxide absorbed from the atmosphere, killed oyster larvae at hatcheries in Washington and Oregon. The Whiskey Creek Shellfish Hatchery in Netarts Bay, Oregon, nearly collapsed before scientists traced the die-off to acidic upwelled water.
Hatcheries installed water-treatment systems and shifted toward more resilient oyster strains.
The crisis put ocean acidification on the shellfish industry's agenda and sparked lasting partnerships between growers and ocean scientists.
It showed how water conditions beyond any farm's control can suddenly threaten oyster supply, the same vulnerability Hog Island faces with the hotel sewage leak.
