Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2006 Tiger Muskellunge* fingerlings 165 61.8

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.

Status of the Fishery (as of 06/04/2007)

Bush Lake is a 188-acre, class 30 lake located in Bloomington. A public boat launch is located on the southwest shore. The lake has a 6 horsepower limit and an 8 mph speed limit is in effect during the day with a 5 mph limit at night. The lake primarily managed for hybrid muskellunge and largemouth bass and is stocked with hybrid muskellunge every three years. One 15.2 inch, 0.6 pound, one-year old hybrid muskellunge from the most recent stocking (2006) was sampled during this population assessment.

Gill net catch of northern pike was 7.5 per net, which higher than average for this type of lake. This population has a low to moderate size structure with few individuals longer than 26 inches. Mean length was 22.5 inches and mean weight was 2.5 pounds, which is right at the median quartile. Individuals up to seven years old were sampled with the 2001 and 2003-year classes accounting for 60 percent of the total catch.

Bluegill, pumpkinseed, and hybrid sunfish are very abundant in Bush Lake but tend to be small. The mean lengths for these species are all less than 5 inches, and few sunfish are larger than 7 inches

Black crappies were sampled between the first and second gill net quartile for both abundance (4.2 per net) and mean weight (0.1 pounds). Trap nets sampled fewer (1 per net) but larger (0.5 pounds) black crappie than gill nets. Mean length was 6.6 inches in gill nets and 7.7 inches in trap nets. Every year class from age 2 through 11 was present, indicating that recruitment has been consistent.

Largemouth gill net catch (1.3 per net) and mean weight (1.5 pounds) were both above average for this lake class. Mean length was 13.9 inches and max length was 17.2 inches. Growth is slower than average for this lake class, taking 6 years for bass to reach 12 inches.

Other fish that were sampled during this survey include yellow perch, black bullhead, brown bullhead, green sunfish, white sucker, and yellow bullhead.
