Helping an entertainment company film great white sharks has landed a hefty fine for a Santa Cruz-based research group.

The National Oceanic and Atmospheric Administration announced Friday that it has levied a $21,000 fine against the Pelagic Shark Research Foundation for violating its research permit while helping a film company obtain footage of a shark near Año Nuevo north of Santa Cruz.

The spot is within the Monterey Bay National Marine Sanctuary, which is administered by the National Oceanic and Atmospheric Administration.

Ray Torres of NOAA said the violation was discovered last August after the Discovery Channel aired the shark video, which was filmed in 2001.

"We would never do anything to hurt a shark," Sean Van Sommeran, executive director of the Pelagic Shark Research Foundation, said Friday. "In our permit it says a film crew can visit us. We followed standard operating procedure."

NOAA said Van Sommeran's group violated two terms of its research permit when it allowed Shark Entertainment to accompany foundation researchers into the sanctuary to film sharks for entertainment purposes. The company was producing "Air Jaws II," a film about great white shark behavior in South Africa, Australia and California.

The foundation was also fined for using a "Hollywood mock-up" of a seal to lure sharks. The permit forbids use of lures in connection with a media venture.

"It was a violation of sanctuary rules," said Torres, a special agent for NOAA.

Although the film was shot in October 2001, it wasn't publicly aired until 2002. Torres said phone calls from researchers and shark enthusiasts helped alert the National Oceanic and Atmospheric Administration.

Torres is unsure whether the Pelagic Shark Research Foundation's permit will be revoked but there could be more restrictions placed on the foundation.

The Pelagic Shark Foundation received a permit in 1999, primarily to be used for tagging, behavioral observation and photo identification of white sharks in the area.
