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

No fish consumption guidelines are available for this lake. For more information, see the "Fish Consumption Advice" pages at the Minnesota Department of Health.


Status of the Fishery (as of 09/07/1994)

The Courthouse Lake fish population has changed significantly in recent years due to flooding. The 1993 flood allowed many species found in the Minnesota River to migrate into the lake, including northern pike. Since Courthouse is a designated trout lake, northern pike are not a desirable species to have present. Therefore a total lake reclaimation was deemed nessessary. This was scheduled for the fall of 1994. During the spring of 1995 rainbow trout will be restocked in the lake.
