Stuck on you

The closures we use on our clam nursery trays are peppered with oyster set.  Oyster larvae settle in July and cement themselves to the closures just as they would to a rock or another oyster.  A new study has described the chemical makeup of the amazing oyster glue.  It is a combination of calcium carbonate (like oyster shells)  and protein that has the ability to wet-set and create a very strong bond.  A better understanding of the glue may help scientists develop techniques to enhance recruitment in dwindling oyster populations, develop adhesives for medicine or design green alternatives to boat anti-fouling paint.  When we bring in our clam nursery trays we take the closures and twist them to pop off  the oysters then put them in a mesh cage to grow.
