Fish Stocked by Species for the Last Ten Years
|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.|
These fish consumption guidelines help people make choices about which fish to eat and how often. Following the guidelin es enables people to reduce their exposure to contaminants while still enjoying the many benefits from fish.

Lake Julia is a 450-acre lake with a maximum depth of 43 feet. The lake is located about 10 miles north of Bemidji in central Beltrami County. There is a DNR public access on the north end of the lake off of county road 26. The Minnesota Department of Natural Resources has classified Minnesota's lakes into 43 different lake classes based on physical and chemical characteristics. Lake Julia is in lake class 31. Other lakes in the same lake class include Black, Deer, Sand, Whitefish, Little Wolf and Upper LaSalle Lakes. Typically lakes in this class are hardwater lakes with regular shaped shorelines. The DNR manages the lake for walleye, northern pike and yellow perch.
Since 1975 walleye fry have been stocked roughly two out of every three years. In the 2003 assessment, however, there was evidence that natural reproduction was also contributing walleye to the fishery. The 1996 and 2003 abundance ratings for walleye were the highest recorded out of 11 assessments since 1970. In 2003 the size of walleye improved from 1996. In 2003 the average length and weight was 17.0 inches and and 1.9 pounds.
In the past northern pike were stocked 12 times between 1954 and 1981 from winter rescue operations on nearby Puposky Lake. There has been no noticeable decline in pike abundance since stocking was discontinued. The 2003 pike catch rate was comparable to other lake class 31 lakes. There appears to be migration to and from Lake Puposky which is a large shallow lake containing abundant prime pike spawning habitat. Its ability to produce pike has been documented by the volume of pike removed in winter rescue operations. Additional areas of prime spawning habitat that are available by connections are Crane and Strand Lakes to the east. In 2003 there has been a reduction in the size of pike from previous assessments. Only 12% of the pike were greater than 22 inches in length.
In 2003 bluegill, black crappie and largemouth bass all were sampled for the first time. Though unauthorized transportation and stocking of fish is illegal, it continues to occur. These species, being native to many surrounding lakes, appear to be harmless introductions. But once populations become fully established, they will certainly be displacing production of other desirable fish species. The most serious outcome of transporting aquatic species of any kind is the possibility of inadvertently transporting one of many exotic species invading waters through out the country. Introductions of some exotic species can cause irreversible environmental damage. We will continue to monitor these three recent introductions to see where their populations will eventually stabilize, and their affect on the rest of the fish community. Bluegill, because of their recent introduction, are still quite small with only ages 1 - 3 sampled. No bluegill sampled were over 6.5 inches long. They are growing fast and acceptable size bluegill will be present in the future. Members of the sunfish family that are native to Lake Julia sampled in past assessments were rock bass and pumpkinseed sunfish. In 2003 pumpkinseed sunfish were still the most abundant sunfish sampled and made up 68% of all sunfish sampled. They ranged in length from 3.3 to 7.4 inches.
Yellow perch are abundant in Lake Julia and provide anglers with quality fish as well as food for predator fish such as northern pike and walleye. Perch had a diverse size structure ranging from 5 to 13 inches.
Another species sampled is black bullhead. Their abundance was well above what you would typically find in a lake class 31 lake. They ranged in length from 5 to 14 inches with an average of nine inches. Their abundance and size provides an excellent bullhead fishery for anglers that appreciate the species.
As with many lakes in the Bemidji area, there has been much development and has likely impacted fish habitat and water quality. Shoreline areas are critical areas for fish production and water quality. Overdeveloped shorelines can't support the fish, wildlife and clean water that is associated with natural undeveloped lakes. The combined effects of all lakeshore owners "fixing up" their property can greatly affect a lake's ability to produce fish and protect water quality. Lakeshore owners can minimize their impact on shoreline and maintain a more natural setting. For more information on how to accomplish this, contact your nearest Area Fisheries office.
