Farming the sea to feed the world
An open-air “nursery” outside the main Wrigley Institute research building is where USC professor Dennis Hedgecock grows the oysters he breeds and crosses in a lab inside. Seawater is pumped into bins, which hold oyster seeds that are about the size of a shirt button. Hedgecock compares a meaty hybrid oyster at right with an inbred oyster of the same age.
