Shad is a type of herring that migrates from the ocean to spawn in fresh water at the start of spring. The American shad is typically 3-5 lb and prized for its ruby red sac that contains the fish’s eggs, a delicacy known as shad roe. After it’s cooked it turns a gray-brown, similar to cooked liver. The taste is subtle, and it easily takes on the flavor of whatever you cook it with. Shad roe season is short. American Shad is being caught off the coast of South Carolina using gill nets and pound nets, which cause little damage to bottom habitat.
