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.|
Long is a 264-acre lake located 5 miles south of St. James in Watonwan County. Long is managed for walleye primarily while black crappie, bluegill, largemouth bass, and yellow perch are managed as a secondary species.
The walleye gill net catch rate of 1.0 fish/net in 2010 was nearly equivalent to 2006. The gill net catch rate was slightly higher in 2002 when 3.6 fish/net were caught. The average length of fish caught in gill nets was only 10 inches; however, the average length caught near shore in our trap nets was 21.4 inches. This may indicate that at the time of the survey, the larger fish were near shore foraging. Starting in 2011 we will be trying a new stocking strategy to try and improve net catches in the future. We typically stock walleye fingerlings (8-10 inches long) in the fall of the year. Starting in 2011 we will be stocking higher numbers, but smaller sized walleye in the late spring to early summer.
Yellow perch numbers were also low in Long Lake based on our survey results in 2010. Lengths of yellow perch caught in our gill nets ranged from 5.4 to 8.6 inches and averaged 7.5 inches.
Black crappie numbers were high in Long Lake in 2010. Lengths of black crappie caught in our trap nets ranged from 6.1 to 9.7 inches and averaged 7.2 inches. Bluegill were also caught in our trap nets in 2010. Lengths of bluegill ranged from 5.9 to 7.8 inches and averaged 6.9 inches.
We do not manage for northern pike in Long Lake but a fair population is present. The average length of northern pike caught in our nets was 25.8 inches with one fish over 35 inches in length.
We did not electrofish with a boat for largemouth bass in 2010 to assess the population but local anglers on the lake some very nice largemouth bass are present in Long Lake. Largemouth bass were sampled with shoreline seines and a back pack electrofishing unit.
Black bullhead numbers were also down but appear to be higher than they were in 2006. Lengths of black bullhead caught in trap nets ranged from 6.0 to 11.1 inches and averaged 9.9 inches.
The freshwater drum gill net CPUE of 39.3 fish/net in 2010 was the highest ever recorded on Long Lake. The gillnet CPUE in 2010 was over twice as high as the gill net CPUE of 15.0 fish/net in 2006 and almost 10 times higher than the catch rate of 3.4 fish/net in 2002. Lengths of freshwater drum caught in gill nets ranged from 8 to 16 inches and averaged 10 inches. The freshwater drum population was dominated by fish in the 8 to 9.5 inch range. This strong year class impacted the 2010 gill net catch rate.
Other fish caught in our nets during the fish survey included common carp, channel catfish, green sunfish, and fathead minnows.
To maintain a healthy fishery in Long 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.
