Fish Stocked by Species for the Last Ten Years
|1 - indicates fish purchased and stocked by private citizens and sporting groups.|
|2 - indicates fish purchased by the DNR for stocking.|
|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.|
Pearl Lake is a 733 acre 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 considered littoral (< 15 feet deep). The lake is primarily managed for Walleye and Northern Pike and in 2009 special fishing regulations were enacted for these species. 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). Pearl Lake was selected as a sentinel lake as part of Minnesota's long term monitoring program (SLICE). This means Pearl Lake will receive more frequent sampling of fish populations, aquatic vegetation and water quality to identify impacts of climate change, land use changes, invasive species, and other stressors.
Walleye have been managed through a combination of yearling and fingerling stocking since the 1940s. Since 1998, the Walleye catch has averaged 5.7/gill net. The 2014 Walleye catch (5.4/gill net) was similar to this average and within the range of expected values for lakes similar to Pearl Lake. Walleye captured ranged in length from 7.5 to 26.1 inches and averaged 16.6 inches and 1.8 pounds. Seven year classes of fish were captured with age 4 fish comprising 46% of the aged sample. Multiple year classes are a reflection of a healthy fish population. Forty percent of the Walleye collected were longer than 17 inches.
Until 1992 the Northern Pike catch was within the expected range (5.6/net). However, since 1992 the average catch has increased to 15.7 fish per net. The 2014 catch (13.4 fish/gill net) was lower than the 2013 survey (20.8/gill net), but similar to the average from 1998 to 2013. Northern Pike collected ranged in length from 11.8 to 39.0 inches and averaged 21.7 inches long and 2.4 pounds. Twenty eight percent of the northern pike caught were longer than 24 inches and 25% were longer than 30 inches.
Yellow Perch abundance has been less than one fish per net since the 1992 survey. No Yellow Perch were sampled in either the gill nets or trap nets. However, 45 were collected during fall daytime electrofishing. These fish averaged 3.2 inches and likely are too small to recruit to gill nets or trap nets.
In an effort to standardize bass electrofishing, seven random sites where chosen around Pearl Lake. Consequently, catch and effort data should not be directly compared to previous surveys. Spring nighttime electrofishing captured 26 Largemouth Bass ranging in length from 6.3 to 16.6 inches. There were 9 year classes present ranging in age from 2 to 16 years old. On average Largemouth Bass reached a length of 13.7 inches at 6 years of age.
Gill nets captured 71 Black Crappie in 2014 for a catch rate of 7.9/gill net which is above average for this lake class. Trap nets caught an additional seven Black Crappie. Black Crappie collected ranged from 4.5 to 11.5 inches long and averaged 8.3 inches.
The 2014 Bluegill catch (9.0/trap net) was low for this lake class. Bluegill ranged in length from 3.0 to 8.7 inches and averaged 5.8 inches. Nine year classes were observed, with age 3 fish making up 35% of the aged sample. Bluegill reached 7 inches in 4 5 years.
An Index of Biotic Integrity (IBI) survey was conducted using backpack electrofishing and seining in July of 2014. A total of 14 fish species were captured, including Banded Killifish, Blackchin Shiner, Blacknose Shiner, and Iowa Darter which are considered intolerant species. They are usually negatively impacted by poor water quality, so their presence in this survey is an indicator of good water quality. Other species sampled included: Black Bullhead, Bluntnose Minnow, Bowfin (Dogfish), Brown Bullhead, Fathead Minnow, Golden Shiner, Green Sunfish, Hybrid Sunfish, Johnny Darter, Pumpkinseed, Tadpole Madtom, White Sucker, and Yellow Bullhead.
