Recent headlines from New England resonated back to the summer of 2001, the so-called Summer of the Shark: A spate of incidents on East Coast beaches had induced a shark psychosis in the mainstream media even though 2001 was by no means a banner year for what reporters too eagerly label shark attacks. The unwarranted fear which ultimately led to a shark feeding ban in Florida was soon eclipsed by the events of 9/11.
Sharks are now back in the news. However, the last decade has seen public perception go through a major change. Sharks have gone from maligned killers that should be wiped out to key players in the ocean in need of our help. For some, sharks have gained, or even surpassed, levels of appreciation normally reserved for more endearing and less-threatening sea creatures such as dolphins and whales. For this reason, many people are more attentive to the whereabouts and well-being of sharks. Most used to gawk and even revel at the sight of a bloody shark carcass hanging by its tail on a dock: A good shark was a dead shark. Some of these same people and their children now frown at the same sight today. Shark killings are being reported. Some people even protest at long-established shark derbies. Tour operators and divers keenly report shark sightings out of fascination instead of fear.
Much science has also been accomplished in recent years on both sides of the border. More has been learned about the Greenland shark in the Gulf of St. Lawrence than was learned in the last century. Scientists are also making giant strides in the study of the white shark off the East coast of the United States. And yet, U.S. and Canadian researchers all agree there are less and less sharks in our waters.
Despite the dramatically decreased numbers, sharks may be moving back into areas that have seen a reduction in pollution and the reappearance of prey species. At the center of the recent commotion, the white shark has been observed in New England and the Canadian Maritimes for several decades. Nonetheless, its impressive size and bad reputation ensure that every sighting generates drama, beach closures, and wild ideas as to why the shark is there.
The return of seal rookeries near populated areas may be playing a part in the reappearance of white sharks in New England. The fact that more white sharks as well as other species are being reported may also be the result of more people looking for them. Many more potential sightings may simply have gone unnoticed in previous years. Also, many a porbeagle shark
(Lamna nasus) has been erroneously identified as a white shark (Carcharodon carcharias) and the media are only too pleased to announce that Jaws is swimming off your favorite beach. This has happened only recently in my native Quebec. Eyewitnesses that had no real experience with sharks made wild claims on national television. When it comes to sharks, the media is often ripe with disinformation and this is detrimental to their survival. In fact, shark incidents are down and some shark diving hotspots on both sides of the continent are actually reporting fewer, and in some cases, no sightings.
Finning in the U.S. and Canada may be illegal, but the threat to many shark species is ever-present. Several 'local' species migrate far beyond our national boundaries into areas where there are no conservation rules. By-catch and targeted fisheries are also taking an unsustainable toll right here off our own shores. Hopefully, tagging studies will shed light on their migratory patterns and some of the environmental factors that influence the movements of coastal sharks. In turn, this will allow scientists to further understand and describe shark behavior as well as propose sustainable actions that will reduce the risk for both humans and sharks.
Good press or bad, as divers, we should take advantage of all the attention being directed towards sharks right now. This is a great opportunity to inform people on the plight of sharks worldwide and on the need to better understand and protect them rather than perpetuate their negative and undeserved stereotype. Otherwise, the singular form of the Summer of the Shark may soon relate to the sighting of a lone shark somewhere off the coast; a once-frightening ghost from the not-so-distant past. ■
