IT is a tale some would say smells a bit fishy, but Kristy Brittain swears it is true.

Last Friday she was kneeboarding behind a boat off Slopen Main on the Tasman Peninsula, east of Hobart, when she was tossed from her board in rough conditions.

In the fall she lost a nose stud from a piercing she had done only a week before Christmas.

Brittain, 25, of Magra, never expected to see the tiny stud again.

Enter a hungry flathead.

You guessed it, the stud turned up in a fish caught by her fiance, Darren Triffett, when fishing with his friend Tim Hall three days later.

Triffett and Hall were in roughly the same area where the stud was lost on Monday. When filleting one flathead they found a tiny nail-like object inside.

"They thought it was a little tack or nail," Brittain said. "I was standing near them talking to them and realized it was the nose stud I had lost in the ocean."

"How could it have ended in the fish? I suppose it would have sparkled and they (flathead) eat pretty much anything.

"But you think how many fish are in the sea . . . and to catch this one."

It's no surprise Brittain regards the stud as lucky. And it won't be lost again.

"I have put it in a sachet so I don't lose it again," she said."I will go and buy a Tattslotto ticket and put this on it."
