Short-Sleeve Unisex T-Shirt
Do you want calcium carbonate? Or do you need calcium carbonate?
These species of Northwest Coast shellfish need calcium carbonate for shell-building and larval survival. That’s a pretty tall order with warm, acidic marine water.
All T-shirt sales contribute to atmospheric carbon and ocean acidification!
Enjoy these species while you can. And don’t forget to check the Washington Shellfish Safety Map before collecting clams, oysters, mussels, and geoducks (with a shellfish license, of course).
