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.

Status of the Fishery (as of 10/20/2010)

Splake were abundant in Moosehorn Lake in 2010, and fair numbers of fish over 12 inches in length were present. Survival of recent stockings had been good, and fish one to four years of age contributed to the 2010 catch. Splake growth had been slightly slower than average for the area. Three-year-old fish averaged 12.5 inches in length at the end of their third year, compared to an area mean of 13.0 inches. Although white sucker were probably present, none were taken in this assessment. White sucker have never been abundant in Moosehorn Lake, and are probably not a factor limiting splake growth or survival in this lake. No other undesirable fish species were found or reported in Moosehorn Lake in 2010.
