JACKSONVILLE, Fla. -- November is traditionally the start of the holiday season, but for the North Atlantic right whales, it is the start of calving season.

Jaxport is trying to make Jacksonville's waters safer for the endangered species.

Barb Zoodsman, from National Oceanic and Atmospheric Administration, estimates there could be only 350 of the creatures left in the world.

"We have a very, very unique place off the coast here, and it's the only calving area in the world for North Atlantic right whales," Zoodsman said.

On Nov. 15, Jaxport will begin the North Atlantic Right Whale Protection & Ship Recognition Program. Its purpose is to applaud owners and operators working toward the right whales' protection.

Vessels can help by limiting their speed to 10 knots and staying in designated travel lanes.

At the end of the season, Jaxport will award flags to the ships that complied as a sign of their commitment to preserving marine life.

Rick Ferrin, of Jaxport, explained the delicate balance Jaxport and NOAA are looking to find.

"This is truly a balance," Ferrin said. "The balance is between commerce and economic development on one hand and the sustainment of our environment and the protection of endangered and scarce natural resources and maritime species."
