|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.|
Gilbert is a 369 acre lake located at Brainerd, in Crow Wing County. The lake is 45 feet deep and about 61% of the surface area is less than 15 feet deep. It is a moderately hard water lake with moderate phosphorus fertility and water clarity that is typical for this area. In 1997 there were 12.6 homes/cabins and one resort located along the 7.8 miles of shoreline. Shallow water soils are primarily sand and gravel, with appreciable areas of muck also present. The aquatic plant community is fairly diverse. Emergent species help cycle nutrients and provide some shoreline protection from wave activity. Bulrush enhances quality of bass/panfish spawning habitat and wild rice does the same for northern pike. Submerged species provide cover and food sources for a wide variety of aquatic life.
The 2004 fish catch was rather variable. When compared to similar type lakes, catches of walleye, pumpkinseeds and rock bass were in the "low" category while the northern pike catch was "high." Walleye fry were stocked in 2001 and 2003 as part of a research project. No fish from these stockings were sampled in 2004, although two larger walleyes were caught.
The northern pike catch was in the "high" cateegor again in 2004. Pike ranged from 13.98-28.35 inches long and averaged 19.5 inches and 1.6 pounds, similar to the 1997 catch. Pike aged 2-6 were sampled and growth was "average." Nearl one-half of the pike were from the 2001 year class.
Largemouth bass were best sampled by spring electrofishing In mid-May 165 bass were sampled. Size ranged from 4.7-17.2 inches, averaged 10.4 inches, and 26% were at least 12 inches long. Ages 1-8 were sampled, growth was "average," and the most abundant year classes were form 2001 and 2002.
The bluegill catch of 9.11/trap net was the lowest to date but remains in the "average" category. Bluegills ranged from 2.6-8.3 inches, averaged 5.3 inches, and about 10% were 7.0 inches or more in length. Ages ranged from 2-9 years and showed fairly uniform year class strength through age 7.
The black crappie catch was "high" in gill nets and "average" in trap nets. In a combined sample, ages ranged from 2-6 years and 78 % were from the 2001 year class. Size ranged from 5.1-12.4 inches and about 12% were at least 8 inches long. Crappie growth was "average."
Special regulations will limit crappie and bluegill anglers to daily bag limits of five of each species, effective in spring of 2005.
