Summary. In April of 2021 while conducting research on sturgeon the U.S. Fish and Wildlife Service was able to reel in a 240-pound female sturgeon from the lower Detroit River. The fish measuring in at 6 feet 10 inches long and weighing 240 pounds was estimated to be approximately 100 years old. Sturgeon being a dying species, this is a very stunning specimen to be recorded especially given the location it was caught. News of the giant being caught by Grosse Ile quickly spread around the community. The lower Detroit River is a very heavily fished area by local sportsmen so news of a sturgeon of these dimensions shocked a lot of people. After a five minutes and multiple failed attempts the group of three was able to land the fish. They estimated the fish to have been born in the early 1920’s but believe it could be even older than that. Commercial fisheries severely overfished these sturgeon because of their great taste and the taste of their eggs, also known as caviar. And if it was not the overfishing that killed one of these fish the destruction of their habitat did. Damming their natural habitats creates difficulties breeding for these fish because they require a strong current to be able to reproduce. On top of those two, water pollution has made living conditions for these fish much worse. A fish with a population so great it was seen as a nuisance now relies on us to help rebuild and clean up what they call home in hopes we can bring back their population to a safe and healthy number.
Why we should care? As an avid fisherman I believe preserving and restoring these waters is extremely important giving it is connected with the largest source of fresh water in the world to help preserve it for future generations.
As an avid fisherman in southeast Michigan, hearing of news like this really shocked me. Not only are sturgeon very rare to catch in general, to see one of this size is eye opening. Its reassuring to know that the Detroit River is still healthy enough to be home to such an astonishing specimen. I believe that it is very important to preserve our great lakes and freshwater. In the past there has been a lot of damage done to them by big companies and negligent people. There is a lot to do to restore these waters, but nothing is impossible. These waterways have been very important in producing and exporting goods and conducting trade, but more importantly we are surrounded by the worlds largest source of fresh water in the world, and we need to do everything possible to preserve it for future generations.
Science in Action.

Kim Scribner is a professor at Michigan State University in their department of fisheries and wildlife. He has recently received a grant from the Michigan Department of Natural Resources. His studies focus on restoring the population of lake sturgeon in Michigan. This is relevant to the topic of my blog because my blog talked about the surprising specimen caught in an area that has been severely affected by habitat damage and overfishing and pollution. Scribner’s work is focused on restoring the population of sturgeon, like the one caught in the Detroit River, and bring them back to a healthy habitat where their population can thrive.
