Shark Incident Information
How common are shark attacks on humans?
Shark attacks are extremely rare in California. While they don't typically prey on humans, sharks may pose a threat if you meet them on their "turf" (or maybe in this case "surf"). Since 1950, there have been 185 shark incidents* in California involving all species of sharks, at least 164 of which involved White Sharks. Of those, 13 were fatal and all of the fatalities involved White Sharks.
It is important to note that while human beach use and ocean activities have greatly increased due to the growing population and greater popularity of surfing, swimming, and scuba diving, shark incidents have not increased proportionally. This is even more evident when looking at incidents where a person was injured.

How can people avoid shark attacks?
There is only one guaranteed method for avoiding a shark attack: stay out of the ocean. While most White Shark attacks have occurred at the surface, there have also been attacks on divers underwater. Scientists agree that most White Shark attacks on humans are unintentional – where the shark mistakes the person for a seal or sea lion. Swimming in areas where sharks have been observed or where White Sharks have been seen feeding on marine mammals is not recommended.
White Shark California Endangered Species Act (CESA) Review 2014 - Listing Not Warranted
On June 4, 2014, consistent with the recommendation of the California Department of Fish and Wildlife, the California Fish and Game Commission determined that based on the best available science, listing the Northeastern Pacific population of White Shark as a threatened or endangered species under CESA is not warranted. The California Fish and Game Commission's decision took effect on August 22, 2014, when the findings were published in the California Regulatory Notice Register.
With the California Fish and Game Commission's action and the related published notice, White Shark is no longer a candidate species under CESA, and take of White Shark is no longer prohibited by CESA. However, take of White Shark is still prohibited in the recreational and commercial fisheries, except for an incidental allowance for gillnet and seine (a.k.a. round haul) vessels (Fish and Game Code §8599; California Code of Regulations Title 14, §28.06). Additionally, a Scientific Collecting Permit is required for the take or possession of White Shark for scientific, educational or propagation purposes (Fish and Game Code §5517 and §8599.3; California Code of Regulations Title 14, §650 et seq.).
Brief History of the Petition Process
The Commission received a petition to list the Northeastern Pacific population of White Shark as threatened or endangered under CESA on August 20, 2012. Pursuant to CESA requirements the California Department of Fish and Wildlife prepared an evaluation of the petition, which concluded that the petition contained sufficient scientific information to indicate listing may be warranted.
The California Fish and Game Commission unanimously concluded that listing the Northeastern Pacific population of White Shark as threatened or endangered may be warranted on February 6, 2013, and designated the species as a candidate under CESA. The Commission's decision went into effect on March 1, 2013, when a notice of decision was published in the California Regulatory Notice Register. After the notice publication, the California Department of Fish and Wildlife provided a written report to the California Fish and Game Commission indicating that listing the White Shark as threatened or endangered under CESA was not warranted.
