Great Whites Are Disappearing in Cape Town, the Former Shark Capital of the World

The Cape Peninsula dangles off the base of Africa like a rough fishhook, curling round from the frigid waters of the Atlantic Coast into the wide expanse of Bogus Bay.

This island-like geography has established a myriad of waves, from spitting beach front breaks and huge-wave reefs to the beginners’ paradise of Muizenberg. Despite the abundance of setups, the peninsula is much a lot more famous for its other maritime sights.

Because the early 2000s, Bogus Bay has grow to be a entire world-renowned spot for cage diving with great white sharks or to witness the stunning breaching phenomenon—where these sharks start themselves into the air even though hunting seals. Fewer stunning is encountering one particular of these leviathans even though surfing, which also grew to become a much a lot more frequent occurrence at the change of the millennium.

Between 2010 and 2016, there were 205 great white shark sightings on common for every calendar year recorded by the Shark Spotters, an firm established up exclusively to watch shark exercise about the peninsula. Many scientific reports approximated there were, a lot more accurately, in between 300-to-500 great white sharks inside the bay, producing it property to one particular of the densest concentrations of white sharks in the entire world.

As a surfer who’d developed up in these waters, I could not enable but really feel marginally unsettled by studies like this even though investigating a story about Cape Town’s shark phenomenon in 2015. But I also took solace in the simple fact that it was surely an indication of a healthful ecosystem. Fantastic whites have been secured in South African waters since 1991, and Bogus Bay was teeming with life—not just great whites, but an abundance of other shark, fish and maritime species.

Then in 2017, the amount of great white sightings recorded by the Shark Spotters plummeted to fifty seven. In 2018, this determine dropped even further to just fifty. By 2019, there were zero recorded sightings, mirrored by a comprehensive absence of white sharks in cage diving encounters. In the space of 3 several years, Cape Town’s apex predators had basically disappeared.

“What we have observed in just the earlier couple of several years has been practically nothing limited of a calamitous crash of our great white shark population alongside the south and southwest Cape shoreline,” states Chris Fallows, a entire world-renowned cage diving operator and wildlife photographer primarily based in Bogus Bay.

Although the imagined of fewer white sharks may possibly make area surfers’ toes curl fewer in the lineup, the ecological implications could be dire. It is effectively regarded that sharks engage in a crucial purpose in sustaining a equilibrium in the ocean ecosystem and their disappearance, states Fallows, may have catastrophic success.

It was in the beginning speculated that the culprits could be a pair of orcas nicknamed Port and Starboard, who were to start with noticed in Bogus Bay in early 2015. Orcas are the only species regarded to predate on great whites and other massive sharks. They normally hunt in pairs, attacking the pectoral fins and ripping the shark open to take in its liver, which is abundant in excess fat.

Between 2015 and 2017, a amount of sevengill and great white sharks washed up on shore with these telltale wounds in Bogus Bay and Gansbaai, one more great white shark hotspot even further east.

Dr. Alison Kock, a leading shark scientist and maritime biologist, theorized that a new sub-team of killer whale that exclusively targets sharks could have moved closer to shore as their offshore food sources declined, transforming the structure of the Bogus Bay food chain. As these new apex predators appeared a lot more regularly in the bay, the great whites had fled.

Fallows, on the other hand, is skeptical that killer whales are only to blame.

“During all encounters with orcas in Bogus Bay and about Seal Island, we never recognized a drop off in sightings of great whites,” he states, citing considerable sets of facts that tracks the presence of orcas in Bogus Bay since 2009. “I am not saying that orca predation does not or has not had an result on white shark residency… (but) these consequences are limited to medium expression, as mirrored in other spots about the entire world wherever orca predation on great whites has in fact been witnessed.”

Alternatively, Fallows believes it is the disappearance of smaller sharks that has had a ripple result all the way up the food chain.

“In the late nineteen nineties, South African fisheries experts gave out demersal shark longline permits,” describes Fallows. “This (sort of fishing) lets quite a few thousand hooks to be established on the ocean ground to concentrate on smaller sharks.”

Precisely, smooth-hound sharks and soupfin sharks, which congregate in dense shoals and were historically abundant in Bogus Bay.

In accordance to Fallows, it is a frequent misconception that South African great whites feed primarily on seals. Alternatively, smaller shark species and bony fish are their most important food supply, producing up sixty p.c of their food plan. These sharks were fished intermittently about Bogus Bay at to start with, typically to health supplement other catches, right up until 2015.

“Suddenly, 3 demersal shark longline permit holders genuinely started out fishing the source hard,” states Fallows. “They uncovered how, wherever and when to concentrate on the smooth-hound and soupfin sharks. Their catches soared as can be observed by the export facts to Australia, wherever the sharks are bought for fish and chips. For the great white, this has been practically nothing limited of a death blow.”

Typically referred to as “flake” in Australia, smooth-hound shark is normally utilised in Australian fish and chips. Numerous individuals really do not even know they are consuming shark—according to Australian seafood labeling regulations, only fresh and frozen fish demands to be determined. After it is cooked, there is no lawful obligation to identify the species and shark is known as almost everything from “flake” to “pearled fillet”, “boneless fillet” and even “monkfish”.

Australia has its individual smooth-hound shark fishing market but it is sustainably managed with rigorous quotas and enforcement. In buy to fulfill the big surplus need for fish and chips, importers merely started out bringing in shark from South Africa,

wherever the fishery is inadequately managed with little regulation.

“For Australia, it is a double acquire,” states Fallows. “They are defending their source from overfishing by getting effectively investigated and effectively-enforced quotas. To make up the need deficit, they import our sharks at a favorable exchange fee. The problems becoming accomplished on the other facet of the ocean is not known to most individuals in Australia, who are unwittingly consuming our sharks in their fish and chips.”

Unlike in Australia, there is no restrict on the total allowable capture in South Africa. Because 2011, the Section of Atmosphere, Forestry and Fisheries’ (DEFF) individual experts have mentioned that these sharks are becoming harvested at an unsustainable rate—almost 3 times the yearly encouraged quota—and have designed urgent suggestions to restrict the total allowable capture, but this has been regularly ignored by administration and coverage makers. To make issues even worse, shark longliners have been documented fishing inside South Africa’s flagship maritime reserves—the equal of longline fishing on the Fantastic Barrier Reef. In 2019, DEFF experts warned that smooth-hound and soupfin shark populations were in a condition of collapse.

Recurring makes an attempt to get a remark from the Section went unanswered, but the science also echoes anecdotal proof I had listened to even though speaking to area surfer Pierre de Villiers back in 2015.

De Villiers is not a scientist. His credentials have been attained by way of a long time of surfing and diving the Cape reefs. Along with Peter Button, he pioneered Dungeons very long prior to there were boats with photographers that dropped you in the lineup. Again then your only possibility was to lug your rhino chaser about the towering Sentinel mountain and make the two hundred-meter paddle out by way of Shark Alley, a deep channel flanked on possibly facet by a rocky seal colony wherever it was jokingly said that white sharks would dangle out like customers at a push-by way of.

A winner spearfisherman, De Villiers told me how, up right up until the early 2000s, the peninsula was teeming with smooth-hound sharks.

“They utilised to occur about Cape Position and into the bay in quantities that were mindboggling. You’d swim above and you’d see a mass of grey factors underneath you. They look… terrifying right up until you understand they can’t bite you. But there were thousands and thousands of them. Men utilised to get a lot more money for them than yellowtail… So they fished those sharks right up until they disappeared.”

Historic and present facts bears out De Villiers’ very long-held observations. Between 2014 and 2018, the total quantity of shark goods exported from South Africa to Australia rocketed from about 8,000 kilograms for every calendar year to virtually sixty,000 kilograms in accordance to Website traffic, the wildlife trade monitoring community. The amount of smooth-hound sharks killed by demersal longline fishing in 2018 on your own was a staggering 30,112—all exported to Australia.

Fallows, and other specialists in South Africa and Australia, are now focusing their initiatives on raising awareness about the issue and making an attempt to educate finish individuals about the devastating affect the fishery is getting by way of a marketing campaign known as Shark Absolutely free Chips—before it is much too late.

“It’s not surprising that the great whites have absent and will continue to disappear even further up the coast as their most important food supply is fished to practically nothing,” states Fallows. “In just 4 limited several years we have observed huge ecological modifications that may never be ready to be rectified, regrettably all for fish and chips.”
