‘The potential application is huge’

From left: Post-doctoral researcher Peter Hundt and University of Minnesota technician Kao Vang work with Emil Kukulski, director of Poland-based ProCom System’s hydro-ecological department, on April 30 in Rice Creek to reposition a chute through which carp will pass when they migrate upstream from Long Lake to spawn in the Lino Chain of Lakes. The Rice Lake Watershed District is testing a low-voltage electrical guidance system. Paired with a Whooshh System (AKA carp cannon), it is designed to remove about 75 percent of migrating carp. Carp removal is one part of RCWD’s $7.3 million plan to improve water quality in Long Lake. Photo Credits: Ann Wessel, BWSR
Matt Kocian, Rice Creek Watershed District’s lake and stream specialist, and Przemek Bajer of the Minnesota Aquatic Invasive Species Research Center discuss progress of the carp removal system being installed April 30 on Rice Creek in New Brighton. A second system would stop juvenile carp from migrating downstream from the Lino Chain of Lakes.
Emil Kukulski, director of Poland-based ProCom System’s hydro-ecological department, was on site for a week to test the electrical guidance system. It was developed to keep native fish out of hydroelectric plants’ water intake systems. In Michigan, it was adapted to control invasive sea lampreys.
Przemek Bajer of the Minnesota Aquatic Invasive Species Research Center, the lead project researcher, was on site April 30 to help make adjustments to the carp removal system in Rice Creek.
Five antennae will monitor the movements of about 1,000 carp tagged last year.
A remeandered stretch of Rice Creek, at left, will be more apparent when the water levels recede. The creek project is one part of Rice Lake Watershed District’s plan to improve water quality in Long Lake.
