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.

Status of the Fishery (as of 07/28/2008)

Splake were abundant in Musquash Lake in 2008, although not as abundant as they have been in the past. Although fish as old as five years were taken, most of the catch consisted of one or two-year-old fish from the 2007 or 2006 fingerling stockings. Fish from the 2007 stocking were seven to nine inches long by July 2008, while fish from the 2006 stocking (identified by adipose fin clips) were 11 to 16 inches long. Despite competition from a very large white sucker population, splake growth had been about average for this area. Splake may have been able to maintain reasonable growth rates because of the presence of fairly high numbers of young-of-year white sucker and fathead minnows.
