Fish Stocked by Species for the Last Ten Years
|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.|
Round Lake is located about three miles northwest of McGregor with a public access located on the southeast side of the lake. This scenic lake is 186 acres in size and has only six cabins and a summer camp located on the lake. The shoreline is lightly developed and has a firm sand bottom ringed primarily by bulrush, which provides habitat for nesting bluegill, pumpkinseed sunfish and black crappies. The lake has been managed as a northern pike, bluegill and black crappie lake.
The fish community in Round Lake has remained stable and healthy over the years. The abundance of bluegill and black crappie have both shown increases since the last survey in 1999. The size structure of the panfish in Round Lake has always been favorable and remained so in 2009. The mean size for bluegill was 6.7 inches with individuals sampled up to 9.1 inches. Although not known for producing large numbers of crappies, catch rates were up in this survey. The average size of a black crappie was 7.5 inches in 2009, with a few fish in the sample between 10 and 12 inches. Anglers can find some decent pumpkinseed and hybrid sunfish as well.
Round Lake is not known as a bass lake. In fact, only 1 largemouth bass has ever been captured in conventional survey gear dating back to 1973. There have been some juvenile bass captured in seining assessments and a few were captured in the seine in 2009, which is an indication that some limited reproduction is occurring.
Walleye occur naturally in Round Lake, but sometimes are stocked when surplus fingerlings are available to boost the population. Walleye abundance has been below average in most surveys to date, including 2009.
Round Lake is unique in that it has a population of a coldwater species called tullibee or cisco. In the past, tullibee numbers have been above average in this lake, and peaked at over 18 per gill net lift in the early 1990's. However, tullibee numbers have dropped for the third survey in a row and are currently at an all time low of 2 per net, which is still near the average for this lake class. Tullibee populations are known to be particularly sensitive to environmental changes, which may have played a role in their decreasing abundance. When available, tullibees can provide an excellent source of forage for game fish, especially northern pike, allowing them to reach large sizes.
Northern pike abundance has remained stable at low levels over the past six surveys, dating back to 1973, and remained low in 2009. The presence of tullibee does not seem to be helping the pike reach large sizes in this lake as the average size was less than 20 inches. Anglers can help maintain and improve the health of the fishery in Round Lake by harvesting smaller pike, and releasing the larger pike.
Yellow perch serve a dual purpose as another important forage species for pike in Round Lake, while at the same time having positive effects on bluegill populations. Densities of yellow perch had been relatively stable on the lower end of the normal range for this lake type, until peaking in 1999 at 11.5 per net. Subsequently, their abundance decreased to 2.7 per net in 2009, which is again near the long term median for Round Lake. Yellow perch exhibited slower than normal growth for all ages except age 1. The largest perch captured was 11.2 inches long.
Other species in the fish community include white sucker, brown, yellow and black bullheads, bowfin, and rock bass.
