Description
Jessica LeRoy and co-authors published a study in 2026 on an invasive fish in the Upper Mississippi River. Silver carp eggs and young drift with the river flow after spawning. Adult carp have been found in the region, but no spawning has been confirmed there yet.
The team ran a drift model for 450 spawning cases, varying water heat, flow, and site. They tracked where eggs would be at hatching and at a later stage when young fish seek calm nursery water. Eggs spawned above a large lake in the river would likely settle in the lake before hatching. Young from sites below the lake would mostly drift out of the study area. The results can guide where crews search for young carp.
