What Are Artificial Reefs?

The Gulf of Mexico has a lot going for it, except for hard substrate, which is necessary to attract marine life. The little bit of hard substrate that we do have out there, we want to maintain and enhance. Dale Shively program leader for the artificial reef program at Texas Parks and Wildlife says they use various materials to create substrate.
