Rocky seabeds off southern California, USA, and Baja California, Mexico.

Major threats

Threats below are drawn from the authoritative sources listed on this page. For the current, complete assessment, see the IUCN Red List.

  • Past overfishing
  • Very low numbers limiting reproduction
  • Disease

Why it matters

The white abalone is a landmark case for marine invertebrate conservation, showing how overharvest can collapse a slow-recovering species and how captive breeding is being used to rebuild it.

Frequently Asked Questions

Why can't white abalone simply recover on their own?
Abalone reproduce by releasing eggs and sperm into the water, so individuals must be close together to breed. Overfishing left survivors too far apart, so captive breeding is being used to help.
Why is the white abalone Critically Endangered?
Published assessments cite past overfishing, very low numbers that hamper reproduction, and disease. See the IUCN Red List for the current assessment.
