Coldwater Hatchery Management

The DNR is making changes to the way it raises, stocks and manages its statewide trout program. Effective this year, the agency will close a portion of its French River Hatchery near Duluth, shift trout production among various hatcheries, and reduce or eliminate stocking in 60 lakes and streams where results have not met expectations or self-sustaining trout populations have been established.

The new approach follows an in-depth assessment by DNR staff and implements various aspects of the DNR's Lake Superior and southeast Minnesota trout plans. Last year, the DNR stocked 2.2 million trout at a cost of $2.4 million. The planned changes will result in an immediate savings of about $70,000 in electrical and feed expenses and up to $200,000 annually when changes are fully implemented.

Water bodies, the DNR's planned action and the reason for the action are listed below.

     

Lakes

BKT=Brook Trout | BNT=Brown Trout | LAT=Lake Trout | SPT=Splake | RBT=Rainbow Trout
Name Action Reason For Change
Ahsub (BKT) Delete Poor survival of stocked trout; competing warmwater species
Bee Cee (RBT) Delete Competition with warmwater fish, no trout survival
Bingshick (BKT) Reduce Per 2009 LMP, evaluate if changing annual to alternate year stocking rate will maintain or improve survival and growth and maintain the long range goal. Lake is in the BWCAW
Bone (Long) (BNT) Reduce Low angler pressure on brown trout
Burntside (LAT) Delete Increase in lake trout natural reproduction, don't want to stock a genetically different strain at this time
Conchu (BKT) Delete Poor survival of stocked trout; competing warmwater species
Crosscut (BKT) Reduce Low angling pressure
Dan (BKT) Delete Poor survival of stocked trout; low angling pressure
Divide (Twohey) (SPT) Reduce Improve growth rate (quota cut moved to Hogback)
East (BKT) Delete Low angling pressure
East (BKT,BNT,RBT) Reduce Low angling pressure
Gadwell (Gadwall) (BKT) Reduce Per 2009 LMP, evaluate if changing from annual to alternate year stocking will maintain or improve long term survival and growth and maintain the long range goal. Lake is in the BWCAW.
Gogebic (Duck) (BKT) Reduce Per 2009 LMP, evaluate if changing from annual to alternate year stocking will maintain or improve long term survival and growth rated. Lake is in the BWCAW
High (RBT) Reduce Discontinue RBT stocking due to poor survival of stocked trout; continue to manage for brook trout and splake
Hogback (Twin) (LAT) Reduce Emphasis on winter splake fishery and to maintain growth rate
Huntington Mine (RBT) Delete Poor growth and survival
Iron Chief Complex (LAT) Add New public access
Kemo (LAT) Reduce Good natural reproduction. Reduced stocking frequency from 1 out of 2 years to 1 out of 4 years. Evaluate natural reproduction
Lima (BKT) Reduce Per 2009 LMP, evaluate if changing from annual to alternate year stocking will maintain or improve long term survival and growth rated
Little Elbow (RBT) Delete Poor survival of stocked trout; low angling pressure
Little Long (RBT) Delete Low angling pressure
Meadow (Lind) (BNT) Delete Poor survival of stocked trout, low angling pressure
Moosehorn (SPT) Reduce Per 2009 LMP, Alternate year stocking is recommended to improve growing conditions for stocked splake by reducing competition for forage
Muckwa (RBT) Reduce Per 2009 LMP, evaluate if changing from annual to alternate year stocking and an increase in stocking rate will maintain or improve long term survival and growth. Past assessments indicate that the long range goal can be met with alternate year stocking. Fishing pressure is light
Mulligan (BKT) Delete Per 2009 LMP, Stocking will be discontinued because it seems likely that northern pike have become established in this lake in numbers high enough to severely limit stocking success
Musquash (SPT) Reduce Per 2009 LMP, a lower level of stocking would probably still produce a relatively high catch rate and improved growth by reducing competition for forage
Ojibway (Twin) (LAT) Delete Poor survival of stocked lake trout
Pine (RBT) Reduce Per 2009 LMP, discontinue rainbow stocking and stock SPT in alternate years are a higher rate. RBT not responding to management
Portage (SPT) Reduce Per 2009 LMP, Alternate year stocking is recommended to improve growing conditions and meet the long term goal in the LMP
Regenbogen (BKT) Delete Poor survival of stocked trout
Sabin (Embarrass) (BKT) Delete Naturally reproducing LAT provide most of the biomass; poor survival of stocked rainbow and brook trout
Section Eight (BKT) Reduce Low angling pressure
Shoofly (BKT) Reduce Low angling pressure
Sock (BKT) Reduce Per 2009 LMP, evaluate if changing from annual to alternate year stocking will maintain or improve long term survival and growth rated. Past assessments indicate that the long range goal can be met with alternate year stocking. Lake is in the BWCAW
Superior (LAT) Reduce Increase in natural reproduction. Reduction due to Lake Superior Management Plan and reduced number of broodfish
Trout (RBT) Reduce Per 2009 LMP, evaluate if survival and growth improves by reducing the number of yearlings stocked and compensate by stocking large fingerling, Past assessments indicated that survival and growth improved when smaller yearlings were stocked
Unnamed (BKT) Delete Low angler pressure, remove lake form the designation list
Unnamed (Peanut) (BKT) Reduce Low angling pressure
Unnamed (Pear) (BKT) Reduce Low angling pressure
West Bearskin (LAT) Delete LAT population now self-sustained. Good natural reproduction and poor survival of stocked LAT
Willard (RBT) Delete Poor survival of trout and competing warm water fish species
