A man caught a fish believed to be at least 200-years-old.

A 39.08-pound rockfish was caught off the coast of Alaska by an insurance adjuster from Seattle.

The ancient monster measured 41 inches, smashing the old record, set by a 32 and a half inch guppie.

With the 32 inch minnow being over 200 years old, one expert said there is reason to believe this latest catch is even older.

IN FACT.... This record-breaking rockfish's birth may predate the US purchase of Alaska from Russia - in 1867.

The man plans to have the fish mounted. A sample was also sent to a lab in Juneau, the state capital, to help determine its age.
