Fraser river sturgeon 700lb?

Brian Westwood fishing for sturgeon on the Fraser River at Lillooet BC with Chris Gage of Fraser River Fishing Charters on 16th June 2008. The fish was 9ft 3ins long with a girth of 5ft 6ins. Estimated weight of 700lbs. The fish took a suprisingly short but arm aching 25 minutes to land.
