Giant sturgeon caught in Detroit River may be 100 years old

The 7ft-long female lake sturgeon was released by a Fish and Wildlife Service team after being weighed and measured

The US Fish and Wildlife Service received quite a big surprise last week, when they caught a giant fish, estimated to be more than 100 years old, in the Detroit River.

The 240lb lake sturgeon was caught by a three-person crew on 22 April, just south of Detroit near Grosse Ile. The agency described the huge fish, which measured almost 7ft long, as a real life river monster".
