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 08/13/2007)

A resurvey was conducted at Big Swan Lake in 2007. Many pieces of shoreline that were eroding in 2002 had been rip-rapped by 2007. A drought occurred during the summer of 2007 and the water level at Big Swan was low during the week of netting. Big Swan is primarily managed for walleye.

Big Swans watershed was dominated by agriculture. Approximately 37% of the shoreline was developed with residential homes. Only 2 types of aquatic vegetation were sampled in early August, and both curly-leaf pondweed and filamentous algae were ranked as rare. Fluctuating water levels (up to an 8 foot bounce) likely limit many forms of submergent vegetation at Big Swan. Curly-leaf pondweed had formed surface mats in some areas of the lake by mid-May, but those had broke down by early July. Sand and silt were classified as abundant shoalwater substrates, while marl, detritus and gravel were ranked as rare. The secchi disk reading was 2.3 feet in mid-August.

A total of 17 walleye were gill netted for a catch rate of 1.4/net, which indicated that numbers were low. The catch rate in 2002 was 10.7/net. Catch rates have been decreasing since the 1997 assessment. Walleye were 12.4-29.2 inches long averaging 21.1 inches. Walleye were 2-11 years old with 9 year-classes present. Growth was fast. Approximately 41% of the gill net catch corresponded with stocked years. The current stocking regime (1lb of fingerlings/littoral acre every-other-year) was initiated in 1991. Gill net catch rates during this regime (2007,2002,1997) ranged from 1.4-13.7/net averaging 11.7/net.

A total of 30 northern pike were gill netted for a catch rate of 2.5/net, which indicated that only fair numbers were present. The catch rate in 2002 was 4.4/net. Catch rates have been decreasing since the 1997 assessment. Northern pike were 18.4-37.1 inches long averaging 25.8 inches. Northern pike were 2-5 years old with 4 year-classes present and growth was fast.

A total of 3 yellow perch were gill netted for a catch rate of 0.3/net, which inidcated that numbers were low. The catch rate in 2002 was 6.2/net. Catch rates have been decreasing since the 1997 assessment. Yellow perch were 8.0-8.7 inches long. Yellow perch were 3-4 years old with 2 year-classes present.

A total of 106 channel catfish were gill netted for a catch rate of 8.8/net, which was the highest ever recorded at Big Swan Lake. The catch rate in 2002 was 5.8/net. Catch rates have been increasing since the 1997 assessment. Gill netted channel catfish were10.0-26.3 inches long averaging 19.0 inches. Trap nets sampled channel catfish up to 27.3 inches in length. Channel catfish were last stocked in 1994 and are now a self-sustaining population. Channel catfish were 2-12 years old with 9 year-classes present.

A total of 251 black crappie were gill netted for a catch rate of 20.9/net, which indicated that high numbers were present. The catch rate in 2002 was similar at 20.0/net. In 2007, gill netted black crappie were 5.3-11.9 inches long averaging 8.0 inches. A total of 57 black crappie were trap netted for a catch rate of 4.8/net, which inidcated that fair numbers were present. The trap net catch rate in 2002 was 33.5/net, but water levels were higher during that assessment. In 2007, trap netted black crappie were 6.4-9.1 inches long averaging 8.4 inches. Black crappie were 1-5 years old with 4 year-classes present. Age 2 fish accounted for 88% of the gill net catch, suggesting a stronger year-class.

A total of 22 bluegill were trap netted for a catch rate of 1.8/net, which inidcated that numbers were low, but this was typical at Big Swan. The catch rate in 2002 was 3.7/net. Bluegill were 3.9-7.5 inches long averaging 6.0 inches. Bluegill were 1-3 years old with 3 year-classes present. The lack of submergent plant habitat, throughout much of the summer, likely limits bluegill at Big Swan Lake.

A total of 113 carp were gill netted for a catch rate of 9.4/net, which indicated that high numbers were present. The catch rate in 2002 was 0.3/net. In 2007, gill netted carp were 13.4-26.9 inches long.

A total of 23 black bullhead were gill netted for a catch rate of 1.9/net, which indicated that numbers were low. The gill net catch rate in 2002 was 59.7/net. In 2007, black bullhead were 5.8-12.4 inches long. Trap nets did not sample any black bullhead in 2007.

A total of 9 largemouth bass were sampled during spring night-time electrofishing for a catch rate of 7.2/hour. Electrofished largemouth bass were 7.1-9.9 inches long averaging 8.5 inches. Trap nets sampled largemouth bass (4) up to 12.7 inches in length. Largemouth bass were all age 2, indicating inconsistent recruitment. The lack of submergent plant habitat likely limits largemouth bass at Big Swan Lake.

A total of 5 smallmouth bass were sampled during spring night-time electrofishing for a catch rate of 4.0/hour of electrofisher on-time. Electrofished smallmouth bass were 7.3-9.1 inches long. Gill nets sampled 3 smallmouth bass ranging in length from 8.5-15.8 inches in length. Smallmouth bass were 2-3 years old with 2 year-classes present.

A total of 9 varieties of fish were sampled during shoreline seining. Young-of-the-year were collected for largemouth bass (4), smallmouth bass (1), yellow perch (2). Also of interest were johnny darter (6), brook silverside (5), common shiner (3), log perch (1), and spottail shiner (2).
