MIAMI (AP) _ The Miami Seaquarium has been issued a $7,000 fine for allowing trainers to work with a killer whale without sufficient protections.

The Occupational Safety and Health Administration issued the citation earlier this month.

The citation is considered ``serious'' by the federal agency. OSHA says trainers worked with a killer whale in a pool and from the side of a pool without using physical barriers.

OSHA has required physical barriers between trainers and killer whales, or that trainer maintain a safe distance from the orcas, since an administrative judge ruled in a SeaWorld case.

The SeaWorld case stemmed from the 2010 death of trainer Dawn Brancheau, who was killed when the six-ton killer whale, Tilikum, grabbed her and pulled into the water.

A Seaquarium spokeswoman didn't return a call.
