Released young white shark on way full speed to Mexico

BEIJING, March 24 (Xinhuanet) -- A young white shark released from the Monterey Bay Aquarium, California, one month and half ago has traveled past the southern tip of Mexico Baja peninsula heading towards waters off the Mexican coast, according to media reports Monday.

This male shark has journeyed about 1,200 miles (1,930 km) in six weeks since it was released on Feb. 5, which was the fastest shark's migration documented from Monterey to Mexico, as aquarium staff said.

"To travel that far, that fast was totally unexpected," said Randy Hamilton, vice president of husbandry at the aquarium.

The shark's journey has been tracked ever since its release with the help of a Smart Position-Only Tag (SPOT) that sent information on its location, while a pop-up tag sent information on the water temperature and depths the shark prefers.

The shark was caught accidentally in August 2007 off Ventura by a commercial fisherman, and kept under observation for 24 days in a 4-million-gallon ocean pen off Malibu. Aquarium staff determined that he was feeding and navigating well in the pen before they decided to bring him to Monterey.

The young shark was seen by more than 650,000 people during his 162 days on exhibit. That was about 8 percent more visitors than aquarium officials had anticipated, and slightly below attendance levels for the prior year.

This is the third shark released from this aquarium since 2004. The other two released before have survived and thrived.

A pop-up tag placed on a female white shark released in 2005 tracked her from Monterey Bay to waters north of Santa Barbara during her first 30 days back in the wild. The second shark reached Cabo San Lucas 90 days after his release in 2007.
