Privately Stocked Fish
* indicates privately stocked fish. Private stocking includes fish purchased by the DNR for stocking and fish purchased and stocked by private citizens and sporting groups.

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 08/16/2010)

Lake Alexander is one of the most popular lakes in Morrison County. Besides being a scenic, clear-water lake, it supports a diverse fish community that offers a variety of angling opportunities. Alexander has abundant offshore structure and has a reputation of better walleye angling success at night or on overcast days. Several resorts as well as three public accesses can be found on the lake. The Lake Alexander Preserve which is owned by the Nature Conservancy is located on the south shore of the lake and is open to hiking. The fish management focus for the lake is primarily walleye with secondary management for northern pike, muskellunge, largemouth bass, and smallmouth bass. A northern pike regulation was implemented in 2003 which requires the release of all pike between 24 and 36 inches with one over 36 inches allowed in possession. The objective of the regulation was to improve the pike population size structure. Lake Alexander is infested with Eurasian Watermilfoil, so anglers should be diligent about cleaning their boats and trailers when leaving the lake. Lake Alexander provides the potential for anglers to catch trophy size fish of several different species. Walleye are a much sought after species on Alexander and a variety of sizes were observed in both the summer survey and spring muskellunge assessment in 2010. Although the summer survey catch was lower than the desired management goal, the catch rate was within the normal range when compared to similar type lakes. Walleye fry stocking has proven to be an inexpensive and viable method of sustaining the walleye population and meeting fishing pressure demands on the lake. Northern pike abundance appears to have gone up since the last survey in 2006. Although summer survey results for northern pike were not that impressive, over half of the northern pike caught in the spring muskellunge assessment were over 24 inches with some over 36 inches measured. Lake Alexander has also become a destination lake for muskellunge anglers, who regularly report catching fish over 50 inches. Good numbers of both largemouth and smallmouth bass can be found in Lake Alexander and quality fish of both species have been documented. Panfish species present include black crappie, bluegill, hybrid sunfish, pumpkinseed, and rock bass. Black crappie provide a popular winter and spring fishery with fish over 13 inches available. Most of the panfish tend to be small by anglers' standards, but, bluegill and pumpkinseed over seven inches can be found. Other fish species sampled in the survey included brown bullhead, tullibee or cisco, yellow bullhead, and yellow perch. Quality size bullhead up to 12 inches can be found of both species. The lake once supported a good tullibee population that provided a popular lake winter fishery, but anglers and netting efforts indicate the population has been low for some time. Tullibee were stocked in 2003 to supplement the population but that stocking appears to have had little effect on the population. Yellow perch were one species to show a decline in abundance since the last survey, but, there were a range of sizes observed in the survey up to almost ten inches. Fishermen and recreational boaters are reminded that they need to be diligent about cleaning both their boats and trailers when going between lakes to prevent the spread of exotics, several of which grow in Alexander. While a large portion of the watershed is forested, much of the lakeshore itself is developed. Good land use practices by landowners can play an important part to protect and improve the water quality of the lake.
