[DNR] Sea lamprey control planned for Trail Creek in LaPorte County
Start Date: 4/21/2014Start Time: 12:00 AM
End Date: 4/21/2014
Entry Description
The U.S. Fish and Wildlife Service personnel will soon apply treatments to Trail Creek in LaPorte County to kill invasive sea lamprey larvae burrowed in the stream bottom.

The applications will happen between April 22 and May 1 in accordance with State of Indiana permits and will take about six days. Application dates are tentative and may be changed based on weather or stream conditions.

Sea lamprey larvae live in certain Great Lakes tributaries and grow to parasitic adults that migrate to the Great Lakes and kill fish. An adult lamprey can consume 40 pounds of fish in its lifetime. Failure to kill the larvae in streams would result in significant damage to the Great Lakes fishery.

This lampricide treatment will target larval-phase lampreys that were spawned before the construction of the Trail Creek Sea Lamprey barrier in 2012. The barrier prevents adult spawning-phase sea lamprey from reaching spawning habitats upstream, thus eliminating the need for future chemical treatment.
