Yves Bisson, the owner of Yves Bisson Sturgeon Company, hooked and landed a 10.6-foot sturgeon on Canada's famed Fraser River on March 6. He estimated that the massive fish weighed approximately 600 pounds. Bisson estimates the fish was about 100 years old. White sturgeon are listed as endangered under Canada's Species at Risk Act. It's mandatory for anglers to release them. As part of a conservation program managed by the Fraser River Sturgeon Conservation Society, Bisson tagged his fish before releasing it. The tagging program is done by 60 volunteers and 35 of them are professional fishing guides. Together, they've tagged more than 68,000 sturgeon in recent years.
