Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2013 Walleye fry 711,813 7.0
2010 Walleye fry 710,187 6.5
2007 Walleye fry 1,014,313 9.7
2004 Walleye fry 710,126 6.5

Stocking Notes
1 - indicates fish purchased and stocked by private citizens and sporting groups.
2 - indicates fish purchased by the DNR for stocking.

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 07/12/2010)

Cedar is a 710-acre lake with a maximum depth of 7 feet and is located in Martin County one mile west of Trimont. The lake is just downstream from Little Twin Lake which has been used as a walleye rearing pond and may be a source of walleye for Cedar in years when heavy rain can cause the lake to overflow into Cedar. Fish Lake near Odin is another upstream lake that is stocked with walleye and may provide walleye for Cedar in years with high rainfall events. Because of frequent low winter dissolved oxygen levels, the lake is managed primarily for northern pike while walleye, yellow perch, and crappie are managed secondarily.

The walleye catch rate of 4.0 fish/gill net was what we would expect for lakes with similar characteristics as Cedar Lake. The average walleye catch rate for the last six population assessment is 3.8 fish per net. The gill net catch rate was 4.3 in 2004 and 5.3 fish/net in 2000. Lengths of walleye caught in our gill nets ranged from 15.0 to 19.9 inches and had an average length of 17.1 inches. The walleye population in Cedar has remained fairly stable despite poor some low winter oxygen levels during the last 6 years.

The yellow perch population is doing very well in Cedar Lake. The gill net catch rate of 49.0 was much higher than the catch rate of 3.7 in 2004 and 2.0 in 2000. Lengths of yellow perch caught in our gill nets ranged from 5.4 to 11.6 inches and averaged 7.7 inches. There were good numbers of perch in the 9 to 10 inch range which should provide some good angling opportunities for perch fishermen.

The northern pike population is also doing very well in Cedar Lake. We would consider the population to be high when compared to lakes with similar physical characteristics to Cedar. Historically Cedar has been a very good northern pike lake. The average gill net catch rate over the last 6 assessments is 7.9 fish per net which is very good for lakes like Cedar. Lengths of northern pike caught in our gill nets ranged from 16.3 to 36.9 inches and averaged 19.9 inches.

The black crappie population is also high in Cedar Lake. The trap net catch rate of 25.3 is considered high and was down just a bit from the fish survey conducted in 2004. The long term average catch rate for Cedar Lake is 14.1 fish per trap net. Lengths of black crappie caught in our trap nets ranged from 4.4 to 12.4 inches and averaged 7.6 inches.

Black bullhead numbers are down in Cedar Lake. The black bullhead trap net CPUE has dropped from a high of 354.3 in 1995 to a low of 6.2 in 2010. Lengths of black bullhead caught in our trap nets ranged from 4.9 to 11.8 inches and averaged 9.2 inches.

Sixteen fish species were sampled during the 2010 population assessment on Cedar Lake. Other species sampled included bigmouth buffalo, bluegill, common carp, channel catfish, golden shiner, green sunfish, orangespotted sunfish, white crappie, white sucker, and yellow bullhead.

To maintain a healthy fishery in Cedar Lake; we need to promote Best Management Practices (BMP's) within the watershed to help reduce nutrients entering the lake. High nutrients and sediments in a lake can cause algae blooms and reduce water clarity.
