Fish Stocking Activity

Fish Stocked by Species for the Last Ten Years

Year Species Size Number Pounds
2012 Walleye fry 132,000 1.2
2010 Walleye fry 204,006 1.6
2008 Walleye fry 132,000 1.1
2006 Walleye fry 132,000 1.3
2004 Walleye fry 131,000 1.1

Stocking Notes
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.

Status of the Fishery (as of 06/22/2009)

Grave Lake (DOW# 11-086; Lake Class 23) is a 377-acre lake located near Remer, MN, and has a public access on the northeast shore. Grave Lake has a maximum depth of 55 feet, and 35% of the lake area is littoral (less than 15 feet deep). The Minnesota Department of Natural Resources (MNDNR) has classified Minnesotas lakes into 43 different classes based on physical, chemical and other characteristics. Grave Lake is in Lake Class 23; lakes in this class are generally very clear, very deep, have a low percentage of shallow water area, and have very irregularly shaped shoreline with many bays or points.

Walleye abundance in the 2009 sampling in Grave Lake was lower than that of similar lakes. Fish from 7 to 22 inches were sampled in MNDNR test nets. Walleye fry are stocked during even-numbered years in an effort to increase the population of this species. The abundance of northern pike in Grave Lake was similar to other lakes of this type. Though many northern pike sampled in 2009 were less than 20 inches in length, fish up to 35 inches were found. The bluegill population is comparable to other lakes in this class, and fish up to almost 9 inches were measured. The number of yellow perch collected was similar to other lakes of this type, however most were small. Largemouth bass up to 15 inches were collected during the 2009 DNR sampling. Other species in Grave Lake include black crappie, pumpkinseed sunfish, rock bass, white sucker, and yellow bullhead.

Anglers can help maintain or improve the quality of fishing by practicing selective harvest. Selective harvest allows for the harvest of smaller fish for table fare, but encourages release of medium- to large-sized fish. Releasing these fish can help maintain balance in the fish community of Grave Lake and provide anglers the opportunity to catch more and larger fish in the future.

Shoreline areas on the land and into the shallow water provide essential habitat for fish and wildlife that live in or near Minnesotas lakes. Overdeveloped shorelines cant support the fish, wildlife, and clean water that are associated with natural undeveloped lakes. Shoreline habitat consists of aquatic plants, woody plants and natural lake bottom soils. Plants in the water and at the waters edge provide habitat, prevent erosion and absorb excess nutrients. Shrubs, trees, and woody debris such as fallen trees or limbs provide good habitat both above and below the water and should be left in place. By leaving a buffer strip of natural vegetation along the shoreline, property owners can reduce erosion, help maintain water quality, and provide habitat and travel corridors for wildlife.
