I often wonder what effect all the "shark tourism" has had on the behaviour of sharks in our waters. Surely somewhere along the line there's going to be some kind of pavlovian response associating the presence of humans in the water (albiet in cages or on boats) with food.
Or sharks leaving the area.
A recent documentary on Natgeo Wild:
The Whale That Ate The Great White' Nature Shock. The orcas have learnt to ram the sharks, then turn them over to take advantage of their weakness; tonic immobility. All the other great whites leave the area en masse, despite the prime feeding season.
As to why the sharks fled after the attack, New Jersey scientist Craig O’Connell believes it was because of the “smell of death” in the water. Tests with lemon sharks show that chemicals released when a shark is killed trigger a violent flight reaction in others of the same species. While this might explain the initial dispersal, however, it does not explain why the great whites would stay away from the Farallones for the rest of the feeding season – especially when later research proved that some of them travel up to 4,000km to be there every autumn.
