ST. PAUL, Minn. (AP) - Minnesota is closing a trout hatchery on Lake Superior, citing failing infrastructure and excessive energy consumption.

The Department of Natural Resources said Thursday it’s closing the 1970s-era French River Hatchery near Duluth because it needs $8 million in upgrades, and because it consumes 10 percent of all energy used by the DNR statewide.

The hatchery produces Kamloops trout for stocking in Lake Superior. It’s a domesticated strain of rainbow trout that can’t reproduce naturally in Lake Superior. The DNR says the hatchery is inefficient because it has to heat the lake’s cold water to a temperature at which fish can be raised. Each fish an angler keeps costs around $160 to produce there.



Fisheries chief Don Pereira (peh-RAIR’-uh) says production will switch to another hatchery until a new strategy is determined.
