Avoiding predators is always challenging, but it’s even harder in human altered landscapes where the escape routes may not be as plentiful as they used to.
Evading large predatory fish in highly disrupted waters is just one of the many challenges faced by the Topeka Shiner, a small, freshwater minnow that lives in prairie streams throughout the Mississippi River basin. This endangered species must also contend with both native and introduced predators, including the largemouth bass, a species favored by anglers.
The Topeka Shiner’s natural habitats have been significantly altered by human activities. Much of the area once covered by Kansas’s historic prairies has been converted to agricultural lands, and many landowners have dammed or dug out areas of stream to create small agricultural ponds. These ponds change and disrupt the habitats of freshwater fish, as do road crossings.
