Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2009 Walleye fry 362,881 3.0

Privately Stocked Fish
* indicates privately stocked fish. Private stocking includes fish purchased by the DNR for stocking and fish purchased and stocked by private citizens and sporting groups.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.
Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.
Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.

Fish Consumption Guidelines

These fish consumption guidelines help people make choices about which fish to eat and how often. Following the guidelin es enables people to reduce their exposure to contaminants while still enjoying the many benefits from fish.

Status of the Fishery (as of 08/18/2008)

Pimushe Lake is a 1,268 acre lake with a maximum depth of 40 feet located in southeastern Beltrami County. A U.S. Forest Service access is located on the east side of the lake off of County Road 39. The Minnesota Department of Natural Resources has classified Minnesota's lakes into 43 different lake classes based on physical and chemical characteristics. Pimushe Lake is in lake class 25. Lake class 25 lakes are typically deep (50 - 75 feet), clear, hard water lakes with irregular shorelines. All species typical of a lake class 25 fish community are found in Pimushe Lake. The Pimushe Lake fish community is dominated by bluegill, northern pike, and yellow perch. No stocking of any species occurs on Pimushe Lake.

Anglers pursue a variety of species on Pimushe Lake including bluegill, black crappie, northern pike, walleye, and largemouth bass. Pimushe Lake is known for its quality bluegill population, and because of this it has a special harvest regulation for sunfish that reduces the daily possession limit to 10 fish. This regulation is intended to maintain or improve the quality size structure of the population. In addition to complying with angling regulations, anglers can help maintain or improve the quality of bluegill populations as well as other species, by voluntary selective harvest.

In addition to bluegill, black crappie is another species popular with anglers on Pimushe Lake. At the time of this assessment, crappie from 10-12 inches in length were common with fish present up to 13 inches. Other members of the sunfish family that anglers can expect to catch are largemouth bass, pumpkinseed and rock bass.

Northern pike abundance in Pimushe Lake has been relatively consistent over the past three assessments and is typical of other lake class 25 lakes. Anglers will catch many pike between 18 and 21 inches with an occasional fish greater than 28 inches.

Pimushe Lake has had a self sustaining walleye population with remarkably stable abundance for over 30 years. Gill net catch rates dating back to 1974 have been consistently between 3.4 and 4.7 per net. The 2008 catch rate of 2.6 per net is slightly lower than previous assessments but well within the normal range for this lake class. It is somewhat concerning that most of the walleye sampled were age-3 or younger and sexually immature. Obviously, mature spawners are critically important to lakes maintained by natural reproduction. Voluntary release of mature females - generally fish that are 17 inches and larger - is strongly encouraged.

Most of the shoreline of Pimushe Lake is under public ownership and not at risk of future development. However, a good portion of the south end of the lake is privately owned and has been increasingly developed over time. This development can degrade water quality and impact valuable shoreline habitat. Native shoreline vegetation provides habitat for fish and wildlife, filters harmful nutrients, and protects against shoreline erosion. Lakeshore owners can minimize their impact on shoreline and maintain a more natural setting while actually decreasing annual maintenance.
