State Marine biologists believe large concentrations of sharks have been drawn close to Alabama beaches to feed on bait fish.
Since Sunday the numbers of sharks have risen from 79 to 91 at sightings about 100 yards offshore.
More than 40 sharks circled yesterday near the Gulf State Park public fishing pier.
Since increased numbers of sharks were first reported last Thursday, conservation officials have not warned people to stay out of the water. But an advisory issued about increased shark sightings is a notice to the public that more sharks than usual are being seen and that swimmers should take precautions.
Precautions include not swimming at dusk and dawn, prime feeding times for sharks.
With the Labor Day weekend near, Conservation officials said the shark notice will remain in effect and observational flights will continue until the number of sharks sighted drops back to a level close to the average of about six.
