Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2013 Walleye fingerlings 2,072 148.0
2011 Walleye 8,250 10.0
2009 Walleye 16,503 10.4
2007 Walleye fingerlings 879 125.5
2005 Walleye fry 110,000 0.9

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 08/11/2008)

Granite Lake is a 339 acre recreational development lake six miles south of Annandale in Wright County. It has a maximum depth of 34 feet. Granite Lake on the EPA List of Impaired Waters because of mercury in fish tissue and high nutrients. Secchi depth was measured to only 3.0 feet on 11 August, and dissolved oxygen dropped from 8.2 to 0.2 between 17 and 18 feet. Aquatic plants were found down to eight feet. Bushy and sago pondweed and coontail were common. Curly-leaf pondweed, first recorded in 1980 on Granite Lake, was found on 22.2% of the lake (75.4 acres). Nongame fish collected were carp; green, hybrid and pumpkinseed sunfish; black and yellow bullhead; Johnny darter; golden and pugnose shiner; and bluntnose minnow.

In 2008, the northern pike catch rate of 4.3/gill net was similar to the 1999 rate of 3.7/ gill net. Both years were near the average for similar lakes. Northern pike ranged from 17-34 inches. Average length was 23 inches and weight was 3.3 pounds. Northern pike greater than or equal to 24 inches were 39% of all pike sampled.

Granite Lake has been stocked with walleye regularly since 1970. It has been part of a statewide study to evaluate stocking that began in 2000. The study involved stocking of fingerlings in 2001 and 2007, marked frylings in 2003 and fry in 2005. To evaluate the effects of the various stocking strategies, gill net assessments were conducted in 2004, 2006 and 2008. The catch rates were all within the expected range. Walleye sampled in 2008 ranged from 10-28 inches. Average length was 19 inches and weight was 3 pounds.

Largemouth bass were sampled by night electrofishing on May 12, 2008. Seventy-eight fish were sampled for a catch rate of 77.3 fish/hour on-time. This was similar to other Wright County lakes at 67/hour. Bass ranged in length from 9-18 inches. Average length was 10.4 inches and weight was 0.6 pounds. Growth of largemouth bass was within statewide averages. Largemouth reached 13 inches by age four.

The catch of bluegill 26.1/trap was nearly identical to that of 1999 (29.3/trap net) and within the expected range for similar lakes. Growth was above lake class averages for bluegill from both trap nets and gill nets, but average weight was low at 0.15 pounds. Bluegill ranged between three and nine inches and 27% were six inches or larger.

The black crappie catch (1.6/trap) was low and somewhat less than that of 1999 (2.8/trap). Growth of black crappie was within averages for similar lakes. Black crappie reached nine inches by age four. However, average weight (0.4 pounds) was above the expected range. There were no fish larger than 11 inches in either trap or gill nets.

A total of 25 yellow perch was sampled in gill nets in 2008. Fish ranged from six to nine inches and averaged 7.4 inches. The average weight was 0.17 pounds. The catch rate was 4.2/net, which was significantly lower than the 1999 catch rate of 19.8/net, but still within the expected range of values. The highest catch rate was 79.0/net in 1980.
