Wildlife crew makes ‘once in a lifetime catch’ of giant sturgeon, likely alive for 100 years


Tipping the scales at about 108 kilograms (240 pounds), this adult lake sturgeon is a touch longer than the wildlife crew members who caught it.

The organization said its Detroit River native species crew caught the sturgeon, which it considers one of the largest ever recorded in the U.S., last week.

“Based on its girth and size, it is assumed to be a female and that she has been roaming our waters over 100 years,” said the Alpena Fish and Wildlife Conservation Office in a Facebook post, calling it a “once in a lifetime” catch.

“She likely hatched in the Detroit River around 1920 when Detroit became the 4th largest city in America.”

The lake sturgeon is billed at six-feet-ten inches — “much longer” than the typical length for this type of fish which is between four and six feet, according to Trevor Pitcher of the LaSalle Freshwater Restoration Ecology Centre.

Pitcher added that lake sturgeon usually live about 80 years but it’s possible for some to live a full century.

In terms of weight, Pitcher has observed lake sturgeon weigh between 100 and 160 pounds and said the Alpena crew’s find was “much larger” than anything he’s seen before.

The fish was quickly released back into the river after it was processed.
