UKIAH, California (17 August 2004) -- The shark attack north of Fort Bragg earlier this week, which caused the tragic death of California sport fishing advocate Randall Fry, serves as a reminder of what other divers can do to minimize the risk of being attacked by the ocean's top predator. It has been confirmed by the Mendocino County coroner that Fry, 50, of Auburn, died from injuries caused by a white shark (Carcharondon carcharias). Fry and his companion were free diving for red abalone 10 miles north of Fort Bragg at Kibesillah Rock in Mendocino County. They were approximately 150 feet from shore and in waters between 15 and 20 feet deep. "It's extremely rare that a human is attacked by a shark," said Kon Karpov, DFG's senior marine biologist and abalone researcher in Fort Bragg. "The best advice is to dive with a partner and to avoid areas with high concentrations of pinnipeds, such as harbor seals, sea lions or elephant seals." While Fry was an avid diver and, according to his friends, cautious and aware of the inherent risks of diving in the open ocean, California Department of Fish and Game experts are reminding people that there are precautions that can be taken to minimize the threat of a shark attack. "It may be a case of mistaken identity or it may be investigatory or territorial behavior," said DFG's shark expert Robert Lea. "The shark's primary prey are marine mammals, and if you happen to look like one, from a shark's perspective, and you are near the surface, you're at risk." DFG recommends that divers who are spear fishing or abalone diving should try to stay in kelp-forested areas where sharks are less likely to be searching for food. Sharks tend to swim in open water areas, both shallow and deep, according to the DFG. While using SCUBA gear is unlawful for abalone diving, it is legal for spear fishing and allows divers to stay close to the ocean's bottom. "Shark attacks occur from the bottom up," Karpov said. "When using SCUBA, divers should minimize their time spent on the surface going for air and when returning to the boat or shore. This will help to decrease the chance of being mistaken for a pinniped near the surface." Another tip is to frequently transfer caught fish to a nearby boat or the shore. This practice is highly recommended as bleeding fish can attract sharks to the site, DFG said. "We can take precautions as recreationalists, but the ocean is not entirely a risk-free environment," Karpov said. Sharks do not deliberately target humans as prey, however, according to the department. "That was likely the case with Fry and a swimmer who was fatally attacked at Avila Beach in San Luis Obispo County last year," a DFG news release stated. "Both were close to the water's surface where they could have been mistaken for a seal or sea lion. Abalone enthusiasts in open water are at greater risk because, as free divers, they frequently surface for air, and can more easily be mistaken for marine mammals." Abalone diving is a popular activity along the North Coast. Many abalone divers from the North Coast dive off Mendocino County's coast each year.

Karpov said that data derived from abalone punch cards indicates that on the average, divers spend nearly 100,000 days annually diving for abalone, and more than 30,000 people buy permits each year. Rock picking for abalone is an alternative to free diving and also reduces the risk of a shark attack. The following are shark statistics recorded by DFG including the latest incident: • Since recordkeeping began in the early 1950s, there have been 11 fatal shark attacks off the California coast (10 confirmed from white sharks). • A recorded 96 nonfatal incidents with sharks have occurred off the West Coast; 83 of these were in California. • The last fatal attack was a year ago. In August 2003, a white shark estimated to be 15 to 18 feet long attacked and killed 50-year-old college instructor Deborah Franzman of Nipomo while she was taking a morning swim off Avila Beach in San Luis Obispo County. White Shark facts: • White sharks play a crucial role in the marine ecosystem by helping to suppress pinniped (seals and sea lions) populations. The only real threat white sharks face are from humans, as well as the occasional killer whale. • Because of their elusive nature, there are no population estimates available for white sharks. However, experts agree that their numbers are extremely low. • White sharks are a protected species in California, Australia, Malta and South Africa. Increasingly, scientists are suggesting that they should be protected in all oceans of the world. • Adult white sharks grow to about 21 feet long and dominate their domain as one of the top-level predators of the ocean. In 1986, scientists were able to measure a female white shark captured off Pt. Vincente that measured 17.6 ft and weighed 4,140 lbs. General tips on how to avoid a shark encounter: • Most importantly, don't swim in or near areas frequented by sea lions, harbor seals, and elephant seals, near their rookeries, or near the mouths of rivers where the animals concentrate looking for fish. • Minimize time spent on the surface. Wearing a wetsuit and fins, or lying on a surfboard, creates the silhouette of a seal from below. Shark attacks are often believed to be cases of mistaken identity, with surfing or swimming humans mistaken for marine mammals. • Dive with a partner and stay alert to your surrounding environment. • Avoid swimming during times of reduced sunlight, such as foggy mornings or dusk, which are ideal times to be mistaken for a seal. • Some high-risk areas to avoid include waters around the Farallon Islands, San Miguel Island, the mouth of Tomales Bay and Ano Nuevo.
