What is it about?

Grass carp are an invasive species in the United States that can have massive impacts on aquatic ecosystems through the consumption of copious amounts of vegetation. The research in this study focuses on describing their upstream movements in rivers in response to water rise events when they are attempting to spawn.

Why is it important?

This research is one of several studies investigating the life history of invasive grass carp. The more information we can gather on their life history will help us to better understand what they need in order to reproduce and will help us to create new ways to slow the spread of the species.


This research offers a new perspective on grass carp behavior in lake environments where the majority of the research in the past has focused on their behavior in large rivers. Our findings will help to bolster the knowledge of grass carp behavior with the aim of managing the species more effectively.
