DNR blames large fish kill near Twin Cities on illegal release of ornamental goldfish

Ornamental goldfish that escaped or were released into a lake just south of the Twin Cities likely infected and killed off large numbers of carp, according to state conservation officials.

A virus from the koi goldfish also has been found in at least eight other southern Minnesota lakes in the past year, the state Department of Natural Resources (DNR) said Friday.
