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 07/27/2009)

Walleye relative abundance was similar to previous assessments. The gillnet catch of 1.4 fish/net was above the 25th percentile for similar lakes. Few large walleyes were sampled, but the average size was good (17.0 in). This was likely an artifact of the age classes sampled. Despite historically consistent stocking efforts only four year-classes were sampled with the oldest individual age 6,. The strong 1999 year-class of walleyes sampled in surveys during 2003 and 2005 appeared to no longer be evident in the walleye population of Lake Calhoun in 2010. Walleye growth was slow when compared to similar lakes.

Northern pike abundances have historically been below the 50th percentile for similar lakes. The gillnet catch of 2.5 fish/net was the lowest abundance observed in the previous five assessments. Northern pike size structure was good, with an average length of 17.8 inches. The average length of adult northern pike in Lake Calhoun is likely larger than this value since numerous small, immature northern pike were unusually sampled during this assessment. The low abundance of northern pike in Lake Calhoun allowed for fast growth of this population. Ages 3-6 were sampled.

Largemouth bass relative abundance (28.8/hr of energized time) and size (12.1 in; 1.1 lbs) were near average for area lakes. The largest individual captured was 18.3 inches and 4.1 pounds. Largemouth bass recruitment was consistent with 8 year-classes sampled. Growth was slightly below the average for similar lakes with fish reaching an average of 14.5 inches by age 6.

Black crappie relative abundance has been decreasing since the 2000 Survey, and fell below the 25th percentile for similar lakes in 2010. Black crappie averaged 7.9 inches. Recruitment was consistent with 7 year-classes sampled. Black crappie growth was slower than average, and fish reached an average length of 7.5 inches by age 6.

Bluegill relative abundance was above median levels for similar lakes, but has been decreasing since 2000. Sampled bluegill averaged 5.2 inches with 0.5 percent of the catch exceeding 7.0 inches. The population is dominated by small individuals where fish reached an average length of 5.9 inches by age 5. Bluegill growth was slower than average, as was also reported in 2003 and 2005 surveys.

Yellow perch relative abundance has been declining since highs reported in 1996 and 2000. Yellow perch average size remained small with only one fish exceeding 7.5 inches. Yellow perch recruitment appears consistent with 5 year-classes sampled. Growth was slower than average.

Other fish sampled during this survey included hybrid sunfish, pumpkinseed, green sunfish, bowfin and tiger muskellunge.
