Giant goldfish are causing problems in Twin Cities

BURNSVILLE, Minn. – Officials in a Twin Cities suburb say they’re finding more giant goldfish, prompting a plea to stop dumping unwanted fish into ponds and lakes, which is illegal in Minnesota.

The goldfish, which grow to the size of a football, compete with native species for food and increase algae in lakes.

Burnsville officials found 10 fish in Keller Lake earlier this month while doing a water quality survey. On Monday, 18 additional fish were found. Some were 18 inches long and weighed about 4 pounds.

City officials have worked with Carp Solutions, a company that develops new technologies for controlling carp, a larger type of  goldfish.
