Title: Silver and Bighead Carp
These silver and bighead carp were collected on the Illinois River to learn more about the anatomy and physiology of Asian carp. This information will guide the development of potential biological or chemical controls as part of an integrated pest management approach for natural resource managers.
Asian carp are invasive species that could pose substantial environmental risks and economic impacts if they become established.
