'Shark Brothers' join Mote to test Gulf sharks for oil

SARASOTA - Sean and Brooks Paxton, known to some as the "Shark Brothers," have dedicated themselves to marine and wildlife conservation.

And a few weeks ago they added Mote Marine Laboratory research team to their bios.

"I'd say it was like going on the greatest field trip ever," said Sean Paxton, 44, about the five-day trip the brothers spent with a Mote crew the Gulf searching and sampling for signs of oil impacting marine life, with a special focus on sharks.

"They're (sharks) feared, but they're also a threatened species, so they do need our help," Brooks Paxton said.

Mote used Brooks, 40, and Sean's expertise in catching and releasing large sharks.

"The first animal was a tiger shark in excess of 10 feet, a beautiful male specimen," Sean Paxton said.

The brothers also filmed some of the trip. The footage shows that big tiger shark slamming his jaws shut as Sean headed toward him on board the research vessel.

"The other animals we encountered in the world of sharks were silkies, a scalloped hammerhead, a mako," Sean Paxton said.

Bob Hueter, who is the director of Mote's Center for Shark Research, led the research trip.

"Yes, the fish can look healthy, but inside the liver, inside the blood, reproductive organs, for example, we can find residues of the contaminants of the oil," Hueter said. "Or their behavior changes and they don't go to the right places to feed and possibly shifting not only populations but the whole ecosystem out there."

Mote Marine Labs Spearheads Shark Effort

(Reuters) - A team of U.S. scientists and environmentalists met with Cuban officials this week to discuss a proposed alliance, including Mexico, to protect the Gulf of Mexico's declining shark population.

The meetings were a product of both improved U.S.-Cuba relations and concern that only a joint effort by the three nations that share the gulf can protect sharks, whose numbers are said to be down as much as 50 percent for some species.

"The Gulf of Mexico is one ecosystem, it's not just the U.S. gulf. The shark is a highly migratory fish that moves between the countries and it is troubled," said Pamela Baker, gulf policy advisor for the New York-based Environmental Defense Fund, which is spearheading the effort along with the Mote Marine Laboratory in Sarasota, Florida.

Shark populations have fallen worldwide, primarily due to overfishing to satisfy China's demand for shark fin soup, which is rising as China becomes more prosperous, scientists say.

An estimated 73 million sharks are being killed annually mostly for their fins, the EDF said in a recent publication.

Still unknown, said shark expert Robert Hueter at the Mote Marine Laboratory, is the effect of the massive BP oil spill this summer in the Gulf of Mexico.
