The Monterey Bay Aquarium calls abalone farming a highly regulated, well-managed industry due in part to the long, intense process of obtaining abalone farming permits from several state and regional agencies. In California, that includes the State Water Resources Board, Regional Water Quality Board, Coastal Development Commission. Once the farm is in operation, several agencies monitor it and any changes to the original facility design must be approved. Despite the existence of abalone farming operations, poaching remains prevalent. A third of abalone traded worldwide is estimated to have been caught illegally.
