Wildlife troopers in Sitka say a fisherman's foot was impaled after an aggressive sea lion snatched most of a large halibut away from him.

On Thursday, Sitka-based troopers got a report about a sea lion at the cleaning dock at Sealing Cove Harbor, according to an online dispatch.

"The complainant reported that while he was cleaning a 70-pound halibut on the dock an aggressive sea lion came onto the dock, advanced towards him and took the majority of the fish," the dispatch says.
