Detroit River, 240 pound fish

100-year-old fish weighing 240-pound caught in Detroit River

A 240-pound (108.8 kilograms) sturgeon that could be more than 100 years old was caught last week in the Detroit River by the U.S. Fish and Wildlife Service.

The “real life river monster” was nearly 7 feet (2.1 meters) long, the agency said Friday on Facebook, where the photo was shared more than 24,000 times by late afternoon.

“Based on its girth and size, it is assumed to be a female and that she has been roaming our waters over 100 years. She was quickly released back into the river” after being weighed and measured, the Fish and Wildlife Service said.

The typical lifespan is 55 years for a male sturgeon and 70 to 100 years for females, according to the Michigan Department of Natural Resources.

This fish was caught on April 22 near Grosse Ile, south of Detroit, while a three-person crew was conducting an annual sturgeon study. Frozen round goby, a tasty snack for a sturgeon, was used as bait on a long line that was deep in the river.

It took about six minutes to get the fish into the boat with a net.
