Why is this Great White Shark smiling?

For this Great White Shark, it's even better now in the Bahamas.

The long-running tourist slogan has a new meaning for all 40 of the shark species around the Caribbean island chain after the Bahamian government banned all commercial shark fishing in the approximately  243,244 square miles  (630,000 square kilometers) of the country’s waters.

What's good for sharks is good for the Bahamian economy. These big fish bring in about $78 million each year, or more than $800 million over the last 20 years, according to the Bahamas Diving Association -- the Bahamas is one of the world's premier shark-watching destinations for divers.

This latest conservation move adds to a 20-year-old ban on longline fishing gear in Bahamian waters. The prohibition on longline fishing -- which often nets sharks along with tuna and other big fish that are the fishers' main aim -- is one reason that sharks are thriving around the Bahamas.

That is not the case elsewhere. Worldwide, shark populations have declined by as much as 70 to 80 percent, according to a report by the Pew Charitable Trusts released last month. Some 30 percent of all shark species are threatened or near-threatened with extinction, and there isn't enough data to make an accurate assessment of an additional 47 percent of shark species, the report said. Because these ancient fish -- they were swimming when dinosaurs roamed the earth -- grow slowly, mature late and produce few young over their long lifetimes, they are exceptionally vulnerable to exploitation. Great White sharks have been documented to live 14 years but probably live much longer. Female Great Whites produce two to four live young every year or two, compared with Bluefin Tuna females, who each produce 10 million eggs a year.
