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 08/10/2009)

Cannon Lake in Rice County is a 1,591 acre lake west of the city of Faribault. A DNR-owned public access is located on the southeast end of the lake at Shager County Park, located next to Minnesota State Highway 60. Cannon Lake is part of the Cannon River system that begins in Shields Lake, loops through Le Sueur and Rice counties, and finally runs to the east, draining into the Mississippi River.

Cannon Lake was surveyed the week of August 10th, 2009 to monitor the fish community and aquatic habitat. Walleye are the primary management species in Cannon Lake. Strong gill net catches on Cannon show an abundant walleye population. Walleyes average 7.3 fish per gill net. Walleye were older and larger, with a mean weight of 2.3 pounds and a mean length of 17.7 inches. Fishing reports have been poor and the lake has been little used by anglers, particularly in the winter.

A strong forage base of yellow perch may help sustain the abundant walleye population. Yellow perch averaged 30 fish per gill net, a value that exceeds the upper quartile for Cannon's lake class. Perch in gill nets ranged between 6 and 10 inches. Perch were prolific enough to be one of the more abundant species in the trap nets, a gear type that is usually ineffective for an open water pelagic species like perch. With more time, yellow perch average size will move into quality and preferred (8 and 10 inch, respectively) stock index values, translating into a higher use fishery. Some good perch fishing has been reported from shore anglers fishing off Rice county road 12 and 13.

Low level bluegill abundance was observed in trap net catches. Young fish made up most of the sample, with just seven percent of the sample being fish larger than six inches. Bluegills are better situated to habitat on the west end of the lake, where there is more aquatic vegetation available, rather than the windswept and more turbid main lake, where vegetation is sparse.

Nearly missing from the survey were crappie. Three black crappies were caught in gill nets and seventeen in trap nets. Crappie ranged from 5 to 13 inches, a wide variety of size and age. With no protected bays and little vegetation, spawning habitat is poor.

Northern pike were gill netted at a rate of 1.5 fish per lift, trap netted at 0.3 fish per lift. Cannon Lake has poor spawning habitat outside of the Cannon river connection at the west end. A strong forage base is available if a strong year class of pike develops.

Common carp were the most abundant fish in trap nets and were modestly abundant in gillnets, at 10.3 and 3.1 fish per net, respectively. Carp have been the most abundant fish in trap nets for the past three surveys.

White bass made another strong showing at Cannon Lake. Gill net catches of white bass averaged 15 fish per lift, above the upper quartile for Cannon's lake class. White bass ranged between 9 and 18 inches.

The biggest change to Cannon Lake since the last survey has been the population growth of white sucker. Suckers have exploded to record high levels in the lake and presently constitute the largest percentage of biomass. 21 white suckers per gill net lift were recorded, weighing an average of 33 pounds per gill net set. Water levels in Cannon Lake and the Cannon River were very low in 2009, so its possible some of the fish may have been concentrated.

22 channel catfish were captured during the 2009 survey. Channel catfish have moved up and down the Cannon River and many lakes within the chain have received supplemental catfish fingerling stocking. The largest catfish captured in the survey was 28 inches; the smallest 12 inches.

Largemouth bass were not observed in 2009. There was not adequate staff time in the spring for largemouth bass electrofishing and bass are not well sampled by passive gears (gill nets and trap nets). One smallmouth bass was sampled in the gill nets. Smallmouth bass maintain a small population on Tetonka Lake within the Cannon Chain, and are more abundant further downstream below the King Mill Dam on the Cannon River. Other fish sampled in 2009 include bigmouth buffalo, black bullhead, bowfin (dogfish), freshwater drum, quillback sucker, and yellow bullhead.

Anglers can help maintain or improve the quality of fishing by practicing selective harvest. Selective harvest allows for the harvest of smaller fish for table fare, but encourages release of medium- to large-sized fish. Releasing these fish can help maintain balance in the fish community in Cannon Lake and provide anglers the opportunity to catch more and larger fish in the future.

Shoreline areas on the land and into the shallow water provide essential habitat for fish and wildlife that live in or near Minnesota's lakes. Overdeveloped shorelines cannot support the fish, wildlife, and clean water that are associated with natural undeveloped lakes. Shoreline habitat consists of aquatic plants, woody plants, and natural lake bottom soils. Plants in the water and at the water's edge provide habitat, prevent erosion, and absorb excess nutrients. Shrubs, trees, and woody debris such as fallen trees or limbs provide good habitat both above and below the water and should be left in place. By leaving a buffer strip of natural vegetation along the shoreline, property owners can reduce erosion, help maintain water quality, and provide habitat and travel corridors for wildlife.
