Protected seal habitat could be cause for shark increase
Surfersvillage Global Surf News, 7 November, 2013 - A rash of great white shark sightings in San Diego waters has surfers, swimmers, and a fisherman wondering what’s going on.
First, a handful of life guards spotted a large triangular fin in North County. Then a fisherman shot video of an 18 foot great white in La Jolla. Lobster divers wonder if the recent population growth in the sea lion and seals have started to draw sharks closer to shore.
“It’s possible the white shark population is on the rise, but I don’t think La Jolla’s pinniped (population) growth has any significant effect on shark patterns,” said Heidi Dewar a shark expert from the National Oceanic Atmospheric Administration.
“It’s hard to get into the mind of a shark. The great white shark feeding grounds at Guadalupe Island have tens of thousands of pinnipeds to dine on. La Jolla has a few hundred,” Dewar said.
