Summary

About 15 different species of abalone are grown for aquaculture worldwide. Abalone from Australia, China, Mexico, and Chile are imported into the US among other countries. Abalone are produced either in closed systems or in sea ranches. The abalone produced in closed systems and sea ranching are Ocean Wise recommended. There are still some concerns associated with sea ranching which include habitat damage from the clearing of ranching sites. Closed system production of abalone does not cause significant habitat damage. There is a moderate risk of escape as abalone are broadscale spawners and release large numbers of eggs to the ecosystem. Disease transmission from farmed to wild abalone can occur, although the industry is well-regulated and consistent monitoring of potential outbreaks occurs.
