LINO LAKES (AP) - Efforts to remove invasive carp from waterways across Minnesota have been ongoing for more than 100 years, but researchers say they've made strides in learning about the fish over the past decade.

These days, controlling the unwanted fish is a more realistic goal, and some research being done in lakes north of the Twin Cities is helping advance that. Research and management efforts in a system of lakes connected to Rice Creek in Lino Lakes involve year-round tracking of adult common carp equipped with electronic tags.

University of Minnesota graduate student Nate Banet says researchers have learned some fish travel more than 8,000 meters through four different lakes.

The Rice Creek Watershed District hopes to use the research on carp migration to cut off their movement and reduce their population.
