Alan Urmeneta, Darren Auramenko, Brant Craig, and Frank Koch were on a fishing trip as part of a corporate team-building exercise.

It took them 40 minutes to bring the prehistoric fish in.

After landing and tagging it for the Fraser River Sturgeon Conservation Society’s monitoring and assessment program, they were amazed to see that the fish measured 345.44 cm in length (fork length) and 154.94 cm in girth, which is a whopping 11 feet, four inches long.

Mulrooney says he’s been guiding for six years, but never came across a sturgeon this large that’s never been previously tagged.

They scanned it repeatedly from tip to tail looking for radio tags.

“I don’t know if I’ll ever see one that big again. I mean I hope I do,” he said.

Every year he learns more about the iconic fish of the Fraser.
