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 08/22/2011)

Pearl Lake is a 733 acre recreational development lake located one mile east of the city of Marty in southeastern Stearns County. It has a maximum depth of 17 feet and 70% of the lake is less than 15 feet deep. Since 2008, Pearl Lake has been included as part of the statewide Sentinel Lakes (Slice) Project and will be intensively studied over a long term. The lake is primarily managed for walleye and northern pike and in 2009 special fishing regulations were enacted for these species. New regulations include: a 17 inch minimum size limit and 3 fish daily bag limit for walleye and a 24-36 inch protected slot for northern pike (daily bag of 3, only one over 36 inches allowed).

Walleye have been managed through fingerling stocking since the 1940s. Historically, the walleye catch has been high. In 2011, the walleye catch was the lowest on record; however, the catch was still above average for lakes similar to Pearl Lake. Walleye ranged in length from 7 - 26 inches and averaged 16 inches and 1.7 pounds. Growth was fast for both sexes. Both males and females reached 16 inches by age 3. Thirty-three percent of the walleye collected were longer than 17 inches and 22% were longer than 20 inches.

The northern pike catch has historically been within the range of expected values over the past six surveys. Since 1992, the northern pike catch has increased significantly. This year the catch was the highest on record. Northern pike ranged in length from 14 - 36 inches and averaged 21 inches and 2.1 pounds. Growth of both male and female northern pike was average. Both males and females reached 24 inches in 5-6 years. Twenty-one percent of the northern pike sampled were 24 inches or larger and 4% were 30 inches or larger.

As the population of northern pike increased, yellow perch abundance has decreased and none were collected in gill nets in 1998, 2008, and 2011.

The electrofishing catch of largemouth bass (87.3/hr, on time) in 2011 was above the Montrose area night time average (67/ hr, on time). Largemouth bass ranged in length from 8.3 - 18.1 inches and averaged 13 inches. Growth of largemouth bass was average. Largemouth bass reached 12 inches in 4 years. Seventy-two percent of the largemouth bass sampled were 12 inches or larger and 27% were 15 inches or larger.

Historically, the black crappie catch has been low. The black crappie catch was similar to previous surveys and within the range of expected values for similar lakes. Black crappie ranged in length from 5 - 11 inches and averaged 8 inches and 0.4 pounds. Growth of black crappie was fast. Black crappie reached 8 inches in 3 years. Forty-six percent of the crappies collected were 9 inches or larger.

The bluegill catch was similar to previous surveys and within the range of expected values for similar lakes. Bluegill ranged in length from 3 - 8 inches and averaged 6 inches. Growth of bluegill was slow. Bluegill reached 7 inches in 6-7 years. Twenty-five percent of the bluegills were 7 inches or longer.

Curled pondweed was mapped during peak abundance and found to be at or near the surface on 41.7 acres or 5.6% of the lake surface. A vegetation survey was conducted on August 22 - 24, 2011. A total of 20 species were sampled. The most common species were chara, sago pondweed, and coontail.

Other species sampled included: banded killifish, black bullhead, bluntnose minnow, bowfin (dogfish), brook stickleback, brown bullhead, fathead minnow, golden shiner, green sunfish, hybrid sunfish, Iowa darter, Johnny darter, pumpkinseed sunfish, tadpole madtom, white sucker, and yellow bullhead.
