|For the record, the largest Northern Pike taken in Minnesota weighed 45 lbs., 12 oz. and was caught: |
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.|
Bloody Lake covers 248 acres and has a maximum depth of nine feet. Because of low dissolved oxygen levels during the winter months, Bloody Lake has been opened to liberalized fishing a number of times in the past. An aeration system was installed in the winter of 1993-94. Oxygen levels did drop to 0.19 parts per million (ppm) in February of 2010 indicating a partial winterkill may have occurred. Eight different species were sampled in the spring when trap nets were set to determine the extent of the winterkill. Apparently the winterkill was minimal in Bloody Lake or the lake had been repopulated with fish from Shetek. In most years, Bloody Lake is connected via a narrow boat channel to Lake Shetek (51004600). Thus, the management objectives of Bloody Lake are correlated to the management of Lake Shetek. Currently, the lake is primarily managed for walleye while black crappie, yellow perch, and northern pike are managed secondarily. Immigration and emigration of walleye and other species will always play a role as long as passage between Bloody Lake and Shetek exists.
Walleye catch rates were lower in 2010 compared to the catch rate in 2002, but still what we would expect for lakes similar to Bloody. Lengths of walleye caught in our gill nets in 2010 ranged from 12.8 to 14.8 inches and averaged 13.6 inches. Larger fish are usually more susceptible to low oxygen levels and may be part of the reason why the largest fish sampled in gill nets in 2010 was only 14.8 inches. Two walleye over 20 inches were sampled in the spring with trap nets when a winterkill check was conducted. These fish may have immigrated into Bloody from Shetek to spawn after the ice went out. Once the larger fish had spawned, they may have moved back into Shetek therefore not be available for sampling during the 2010 population assessment on Bloody. Because of the apparent winterkill of 2009-2010, walleye fry were stocked in both Bloody Lake and Lake Shetek. Bloody has not been stocked in the past due to the connecting to Shetek, but we felt the winterkill was significant enough to try walleye fry.
Yellow perch catch rates were also lower in 2010 than in 2002, but still within the range of what we would expect for lakes similar to Bloody Lake. Lengths of yellow perch ranged from 6.0 to 9.1 inches with an average length of 7.1 inches. The average length of 7.2 inches during the 2010 winterkill check was similar to the average length observed during the summer population assessment.
As with the walleye and yellow perch catch rates, the black crappie catch rates were lower in 2010 than catch rates observed in trap nets in 2002. Even thought black crappie numbers are down some, the population is still doing very well. Lengths of black crappie sampled in trap nets ranged from 3.8 to 12.9 inches and averaged 7.1 inches.
Northern pike catch rates were up slightly when compared to the 2002 and the 1996 population assessments. Ponds upstream of Bloody are being used as northern pike rearing ponds and the offspring are being released into Bloody Lake. Because of this annual influx of northern pike fingerlings, it is likely that the northern pike population will increase in Bloody Lake.
Other species sampled included bigmouth buffalo, brown bullhead, channel catfish, orangespotted sunfish, quillback, white crappie, and white sucker.
To maintain a healthy fishery in Bloody Lake; we need to promote Best Management Practices (BMP's) within the watershed to help reduce nutrients entering the lake. High nutrients and sediments in a lake can cause algae blooms and reduce water clarity.
